The cost per tag is way less than 6 cent when you buy in bulk. My company purchase tags from Alien Technology and pay a fraction of that price. In Europe the frequency is 868Mhz and you can read them from over 5-7 meters with the proper equipment. The major issue is metal or water in proximity to the tag or between the tag and reader. That is why they can't put the tags flat on the cans. The tags most likely just contain a I'd number of few bytes. The communication protocol is pretty advanced though because you need to be able to handle hundreds of tags in the same area so it implements collision handling where you can tell tags to sleep when you have read them. You can also reprogram them. Let me now if you want to know more.
Björn Nilsson sounds very promising, are there other limitations to this technology that prevents it from being adopted widely as a replacement to barcodes and/or backup to barcodes?
Joel Bright I don't have so much experience using it for that purpose, but as I remember, Walmart was planning to replace barcodes with rfid many years ago. Price used to be a big issue before, not sure if it still is, maybe for really low cost items. But barcode readers have evolved as well so I guess there isn't as big of an advantage using rfid and then the downsides are still there. You need to apply the tags, they stick out awkwardly, increase cost, read range can be challenging to control so you read tags far away or miss tags that are close. Etc.
> 5-7 meters with the proper equipment Years ago, when I was doing inventory for the store I worked at, I wished I could just RFID everything. A scan of the shelves would tally things up more accurately and would take a tenth of the time I did manually counting by hand.

I'm Chinese and I was wondering what's inside a cashier-less store like this, then I saw this video and everything explained. Keep it coming, really wanna see more!
I live in a 3-tier city in China and we have more than 2 cashier-less stores. I think there is another checker near the door to make sure its consumer has paid for his goods before the door opens.

Hand-held readers exits which puts out 1 to 3W of power and can read thousands of tags even as far as 5-7m away under 10 seconds. Basically we just entered the room, walked around for a minute and the inventory was done. "Traditional" RFID/NFC can only deal with one active tag.
Brafilus I'd assume that you can only do that in China. Outputting more than a few hundrete mW in Europe and the US in the 868 and 900 MHz Band is illegal ;-)
none of the tags shown where active tags. all of them were passive. most of rfid is passive tags anyways. and: you require a lot less power on UHF than you do for HF tags. HF Tags are working near field (magnetic component of the HF field) to transmit energy to the tag like a transformer. UHF tags are working in far field. HF systems by the way can work easily with 10-20 tags at the same time. Its all about anti-collision which works differently for UHF systems. There is really a lot of missconception around when it comes to buzzwords like RFID, NFC and all that sort of stuff...
Really interesting conversation, I understand how all of the technology that you are mentioning works. Like a key that if detected is registered in the system. The tag is only there to be identified not to perform calculations or respond. Most shops only need to know what items are stocked, how many of each are available and what items are being taken out of the store or coming in. Thus tags that are designed to be identified in bulk just make sense. Would only have to be on the lookout for people trying to destroy tags or cover them up in faraday cages. Passively monitoring everything in the store and having security on hand can be helpful in this situation. Makes so much sense I'm wondering what is stopping the technology from being adopted as a backup to the barcode system and eventually replacing it...
The tags need to be designed in such a was that they get destroyed or otherwise damages when the sticker is removed... Does not seem like it is though.
I love the way he conned his buddy to get a free beer. "Can I borrow your phone? Mine has a dead battery." "I kinda think it's beer o'clock, do you want a beer?" Alright, free beer!
Dude is properly Chinese now. Back when I was in primary school in Beijing, we'd always say things like "can I borrow a piece of paper" or "can I borrow your eraser"? The papers are never returned, obviously. And the erasers are returned after we use it for a bit, meaning it's not "returned in full"-- just like his buddy's phone wallet was returned with a little bit of money gone.
Checked Chinese news, 兔兔到家 (the name of the cashierless shop), seems to be an indie/small group/startup operation that launched the shop from around 2017 but probably spent years in developing all the tech. Dont know how well its doing because its pretty much unknown on Chinese news except for in Yiwu.
I live in China and often travel to tier 1-2-3 cities and villages for my work. There are only a few such stores in China. The government does not like promoting anything that reduces employment. QED. What it does not mind doing however is allowing such companies to trial their products in Chinese cities (beta testing) so that they can then export them to developed western nations that wish to replace humans in stores (or don't have people for it). Australia, USA, Scandinavian remote regions... For example, Shenzhen, a hi tech city where you only see pure electric scooters on the pavements and roads, and where nearly all our street lights are solar powered LED, and 20% of the buses are electric, where most people make smaller payments using wechat bar codes (on their smart phones), there are just a handful of such stores. I havent even seen a single such store in Nanshan, even thoug there are tens of thousands of convenience stores and shops.
I worked with RFID in the Late 1990s. The supplier I worked with was bought by Hughes ID (HID). They used standard HP inkjet ink to print paper tags for a project that we did with the Postal service. The standard HP ink jet ink is conductive enough to make a good antenna.
In a Spanish clothing shop, they use also rfid on every label price. but the coolest thing is, they have a device what can find the location of the tag. in other words, they can find thiefs even outside of the store and also its easier after shops closed to find all laying around clothes and hang these back to the belonging places.
Christian Schnitt what is the maximum distance you have been able to read one? I'm wanting to work on an experiment to see if I can make a very sensitive antenna to pick up lost pets RF chip. It would be awesome just to reach 200 feet
This is interesting. I’ve just found out that Uniqlo now are using rfid tags on every label. At first i dont know whats the function of these rfid tags that they put on the label. Wow. Do they really able to locate the location of the item eventho they are outside the shops? Thats crazy.
Same here in Finland, in my local grocery store they put those rfid stickers on some seemingly random, and usually low value products. I guess those are the most commonly stolen items.
@@oldskoolhead0 gets locked in* i guess you can smash the door but you also scanned your phone and in china phones are tied to your "social security" card so they can find you pretty easily probably
That concept in its entirety is mad brilliant. If you could integrate RFID or NFC into the packaging, you could almost completely automate an American convenience store. You might have to have one or two employees for a 7 Eleven or Lawson scale store in order to maintain shelves authorize alcohol, tobacco, and gasoline sales, but it would make management and operation of them way easier. I could totally get behind this business model.
Honestly, all the videos that are on this channel make me interested in things I never would have cared about before. The way they’re presented is fantastic. I love the down to earth way you go about things and the way you are obviously excited about everything you come across. Keep it up 👍
Thank you for this episode. When I saw that store in Colin's Yiwu video, I was very curious about it, and hoped you would talk about it in a future episode.
The RFID-tag does not transmit anything. You saw how it loaded down the transmitter on the frequency sweep he did on the miniVNA? RFID-tags communicate by modulating how much it's loading the transmitter. Say you have a small transmitter at 850 MHz and the chip gets near and loads down the transmitter. This can be detected in the power usage in the transmitter. The tag will modulate (morse code, on/off, just WAY more complicated) and the power usage figure is decoded and data comes out :)
You are describing an NFC (near field communication) chip read process. There the item needs to be placed very close, almost touching, the reader. This was an UHF RFID chip (completely different wavelength range), that can be read from meters away. It diffracts (reflects with alteration) back the signal it gets from the reader, and that's what the reader picks up. So it actually does send a response, not just cause a "disturbance in the Force" like in NFC.
Man, technology has come a long way. Who would have thought, say 50 years ago, that we would be able to have a cashier-less store and paper-thin, passively-powered tags that can be scanned by just being near the counter.
I'm so glad Scotty is doing these videos. If you look around UA-cam, most people are just making videos about the worst things they can find in China to complain about for the bandwagon views. When I visited China it was extremely friendly towards Westerners and my only complaint is about the cigarette concentration, but that is also going down.
BigCliveDotcom is doing this for years, actually :P. Up to the point that watching some of his cheap Chinese USB chargers he got sent to from viewers has made me incredibly cautious about seeing people using them and without any reluctance handling their metal-cased phone....
Christian von Delius if you are buying development boards (arduino, espruino, etc) or LCD panels it is perfect for that. But then you start buying big RFID readers, genuine security cameras (when it arrives first thing to do is install Dahua firmware to it and change password) and stuff like connectors or terminal blocks it goes too far. Then you discover things like RuiDeng power supply modules (only place they sell them) that are worth their money. Then you come across a Andonstar ADSM302 with free DHL shipping and you have no choice to buy it.
@@felenov So is Alibaba & Taobao better than Aliexpress? I have noticed the price of electronics keep going up and up and up on Aliexpress, my guess is simply because they can, because people will pay it. Are the prices on Alibaba & Taobao more reasonable than Aliexpress these days?
@@skins4thewin Sellers love playing with the prices. They raise the price and discount it. Or the moment the sale starts, prices go through the roof. So be careful and watch the prices, then you will be good. Also asking the seller to give more information about the product sometimes gets you a lower price
@@felenov Hm, I have only seen prices get raised from what I have seen, but perhaps that is due to the types of products I look for, which is mainly electronics and video game related items. I suppose because Americans are willing to pay more for them they feel they can raise the prices accordingly. Shame to hear that about prices going up during sales, that's a shame. Either way, do you think that either Alibaba or Taobao has better value than a place like Aliexpress? Am just curious.
Fikri Rizaldi Kamil I don't know I tried ice-cream not the fruit by itself in China, it's not as bad as they make it look but I'm not a fan and can think of many delicious fruit.....it tastes bad...
My guess is they use rfid because it's more thief proof than Barcode. Because with barcode you can scan cheap items but you actually bring out an expensive one. Or You can even go out without even paying anything.
Bar codes dont have the ability to send information back to the reader. As far as swapping RFID tags with a lower-priced product, there are ways to verify if something has been tampered with. Such as using a product's weight as verification. Many self-checkout systems (in the USA) use this method to catch would-be bar-code swappers. This is why after scanning an item, you usually have to place the item in the bagging area (which serves as a scale) so that the added weight can be checked against the known weight of each item. They may also use a camera to make sure the product visually matches the product reported by the RFID tag
Unnamed Review Guy China still has a lot of high technology but many Foreigners don't know that China is a big innovator. China's rise has been unstoppable, and that is the trade war America has waged against China. America is bound to lose this trade war.
Those are called "UHF RFID Tags". The tranceiver is capable of reading muptiple tags at once. That means that you could have placed those items on a cash register in the shop at once (like in a shopping bag) and it would read all of them at once without a problem.
I remember reading an article several years ago that Walmart was actively researching options to attach tags to all retail products but they need the price of the tag technology to less than $0.01 per tag to meet their business demands. Also recently received a pair of Five Ten sneakers owned by ADIDAS company. When I was removing the cardboard paper tag from one of the shoes and noticed the paper splitting I discovered this same type of tag was sandwiched inside. So of course I rinsed off all the cardboard paper fivers from the sticky film the antenna and chip was attached to and wound up wit someone very closely to what you have. At fist I though it was a loss prevention tag but I now think its more an asset ID tag for contactless inventory and next gen POS purposes. Great video and god I bet that durian ice cream pop was interesting! LOL
In USA if there would have been put a similar one there it would not have been broken into or hacked into, the whole store would just have been plain stolen.
It is actually nice that Chinese society apparently has this level of integrity that this system will work. Sad note on American society that I agree with your comment.
Amazon Go primarily relies on computer vision (and scales). Amusingly enough, the company that makes these RFID chips (Impinj) is located next to Amazon's headquarters. I assume Amazon Go relies somewhat on crowdsourced verification of their computer vision analysis (via something like MTurk), so there's probably still some humans in the loop. The real question is whether computer vision (with human augmentation as needed) will end up being cheaper than putting a tag on each item. But with tags on everything, you can get more benefits: a fridge that knows expiration dates and potential product recalls of everything inside, automated recycling sorting, seamless returns based on the unique ID of the tag, etc.
awesomeferret actually Alibaba group, giant company just like Amazon in Asia. They have 20 outlets without cashier just like the only Amazon Go in Seattle. JD.ID X , first AI based supermarket in Asia outside China in Jakarta, Indonesia. I’m an Indonesian and surprisingly JD.ID X sells stuffs with the same price like other normal supermarket and even cheaper for special deals. You don’t even need to scan or put the groceries on the scanner just walk and confirm your face.
So I just started working for a company called Triple Crown, im a technical recruiter and I have learned so much about what you do and enjoy this channel even more now than before. I just spent all day looking for an rfic design engineer with mmwave experience. You should do a video on that, mmwave tech.
Not really an apple fan myself, but I must say your character is so energetic that I love to watch every video of yours! Keep up the good work, it is highly informing and I already learned so much from you!
It's just conductive ink antenna. You can get conductive ink for your printer and even for 3D printers. "It's not that hard"...... 😜🤣🤣 I love your optimism. 😂😂😂 I'd like to see your antenna results. Or rather your bumbling and stumbling into a sort of working results 🤓🤣👍 Great video man. Thanks for sharing.
I think there are probably cameras as well, but don't remember offhand. Petty theft like this doesn't seem to be as prominent here as a lot of other places I've been. Not to say it doesn't happen, but it happens a lot less as far as I can tell. So things can be more relaxed without it being a huge problem. For instance, I see bicycles and ebikes all the time that are just locked with a simple chain through the rear wheel...
maybe in the walls near the door they have another RFID reader that verifies that the data it reads match exactly with that of a recent purchase made...you know like guards outside malls do! just a guess
I've taken apart exact RFID stickers like that from cell phone accessories (likely from China) YEARS ago. Like 8-9 years ago at least. I don't remember if the chip was that small. I didn't analyse it as well as you did. The antenna was identical though. They also sell those antennas to stick on your phone to "boost reception". Cool tech. Thanks for the video
Hell yes to more RFID. Maybe even get one implanted. I have two and they're great for hacking. One even works with the local hackerspace door access system.
Brandy Wasay no, the majority foreigners works in china as English teacher or reporters, don’t be salty just becuz others have better technology and living conditions than u do.
well, they could sell 100 through hole transistor for a dollar and thats including shipping cost. shouldn't surprise anyone if they could make one of those RFID tag under 2cents each.
I don’t care what you make your videos on because they are all interesting. Thanks for making both entertaining and interesting videos about life and technology in china.
I love hate how your geeky enthusiasm forces me to watch your videos! I mean, I don't get to see these things here in Canada but heck, I can't stop watching what new tech you come across and the tribulations of understanding it.
Yeah, I was thinking the same. I think there was another QR code for you if you weren't buying anything. I may be wrong, but I was thinking about what if there was a power cut, and you'd be locked inside
They need somebody to keep an inventory of stock and stack shelves and to set prices for the items in the system also label prices on items and notify customers of offers as well as to keep the premises clean
+Strange Earth, the RFID stickers are made with printed Silver Chloride. There's a company based in San Rafael, California called Byte Foods that sets up mini refrigerators in offices and lunch rooms that sell food.
For some reason it fascinates me when American's (like myself) live in Asian countries. The logistics, culture change, currency change, even languages are so interesting and I love watching videos of interest where this dynamic is at play, OH and antennas too.
Those stickers look like UHF RFID tags (UHF can have pretty huge read ranges). They come in an insane variety of antenna shapes and ICs (depending if you want read only, or user writable data, or even onboard sensors if you want active tags). The copper coil ones however (like tap cards) are probably LF or HF RFID. They aren't designed for longer range reads (because you only want to read at a close proximity).
Where I work every piece of clothing has an RFID tag and we use that to perform stock takes really easily. What used to take a whole team of 10+ people an entire day to complete now takes two people an hour. This means stock takes can now be done weekly instead of yearly. We don't use the RFID for selling but I guess we will see what the future holds.
any chance of exploring an e-reader/e-ink factory, like the screens made for kindle or kobo (lots on Alibaba, would be cool to see if company photos are real or fake as well)
Guess we are all bound to have our phone as our wallet :) In Denmark it will probably be Mobile Pay app that wins. And lol that Durian ice cream...WTF, apparently the fruit is not allowed on public transport etc cause it stinks.
Vipps in Norway; the only place I still have to use a card to pay is in the local grocery store and Burger King who both signed up with a competitor that went out of business. Ideally I'll have an app on my watch soon so I don't have to bring my phone either.
More info on these types of tags: -cost is fractions of cents (typically 0,1c), so well adapted to convenience store items -the frequency they work at is typically 866, 916 or 920 MHz, close to GSM frequencies which allow for more efficient antenna within the available volume -typically, the chip is very simple and just sends an identification number back -they can be read from a distance of a meter (or more depending on the reader), so I suppose that there is a reader at the exit to check that the customer does not take extra items out -the latter is probably the reason for the QR code scan: the customer is identified when coming in. At the exit, the system checks what is near the exit reader: a phone and a collection of tags. If the two do not match the bought items, the door would not open, I suppose. Presumably, they use near field communication on the phone to insure positioning within that volume.
Whats to stop someone paying for the cheapest item and ripping off the tags and stealing a heap of other items? Is it an honesty system or is there other types of security?
besides all the Skynet and other crazy stuff, manless shops make sense as long as the system is good enough to keep the lost on shoplifting less than hiring a cashier
It's not very hard for someone to stealthly sneak a tag off of the item you take and put it on another item on the shelves, and then keep that out of the camera's line of sight, they won't know you took a extra item, and can't prove it in theory since the tag is still in the shop, plus their system doesn't alert them of shoplifting of removed tags if said unpaid tag does not go anywhere near the door. Remember that all systems can't be fool proofed, unless you weld the tags to said items so it's not removable, OR hide it on said product so one would not know where to look to remove it..
Watching this, only one thing comes to my mind: My country Ghana and the entire African continent need to abandon our current educational system and adopt new ones that relates to practicals and creativity. How do you teach physics and the sciences at universities and import wheel-barrows? How do you teach wood technology in schools and import tooth picks? How do you teach all engineering course and yet all our roads are built by foreigners? God help me
South Africa has the same issue. The current president is gushing about the 4th Industrial Revolution benefits to the country, but doesn't take into account that a basic thing like electricity can go out at the drop of a dime. The basics aren't even properly in place, and they are already jumping over the intermediate to the advanced level of technology. For a person that is hungry and has no smartphone; of what use is free municipal wifi to that person? o.0
It was fun to see how RFID tags really look. My local library (in Shenzhen China) has been using them for a few years now. I saw a similar unmanned store in Quanzhou (Fujian) last year. Fun fact - Very few Chinese people were using it! They were all using the manned convenience store located opposite to it instead. Not seen any such shops in Shenzhen, but there are two such cabinets below my building with small conveniences like small milk cartons and drinks - both work on a similar principle, but using wechat. I think the Chinese are making them and beta testing them in Chinese cities, so that they can export them to developed countries where people enjoy the idea of employing fewer people (low overheads, low prices). A bit like Luck in coffee's unmanned coffee stands.
Why do you ask if we would like to see when you try to make your own antenna? You know we do, all your videos are amazing! Always joy and lots of fun when a new Strange Parts video pops up! :)
Is so funny Stuart saying "Oh, you should make your own antenna....." Like how you actually explain the process you are going through. Makes me think of the phrase. "Inquiring minds want to know...."
Passive RFID stickers are just an antenna and small wire that creates a resonance. They have no chip exactly. That strip in the middle is just a tuner essentially. Whereas active RFID are actually inductive coupling (wireless charging) devices for power that interrupt the coupling to send information back and forth. These have microchips and are reprogramable.
@@jackdavies5331 way way less when buying bulk more like 5-10, I work for a big retail store we pay 8c for 1 water bottle, of course we buy huge amounts so maybe that's it
Does it occur to you.. what is the purpose to open a self service shop in a country with over a billion ppl? Doesn't it create an imbalance of economy, if u have a shop u expect to sell goods to ppl for money, but on the flip side, ppl need to sell labor for money also. Jobs is in direct proportion to economic output/sustainability
There are two kinds of RFID each differ by their mode of operations. (1) Near field magnetic coupled method uses close loop induction running at hundreds of kHz, are less complicated and easier to develop and (2) far field electromagnetic radiative method uses open loop (dipole or its derivative) induction, very small yet complicated quite difficult to develop successfully. For near field type the range is 10cm max very low cost and high volume, while far field type range is 10m or so and relative expensive. The one in this video is dipole coupled type.
I've seen the future it's evil. They are putting this crap into humans and rendering it the sole means of exchange in places. Through it corporations and governments can even track your every movement. No good comes from this technology. No good ever will come from this technology. Destroy it while you still have the chance lest you be rendered branded cattle.

In Europe the frequency is 868Mhz and you can read them from over 5-7 meters with the proper equipment. The major issue is metal or water in proximity to the tag or between the tag and reader. That is why they can't put the tags flat on the cans. The tags most likely just contain a I'd number of few bytes.

Makes so much sense I'm wondering what is stopping the technology from being adopted as a backup to the barcode system and eventually replacing it...
The tags need to be designed in such a was that they get destroyed or otherwise damages when the sticker is removed... Does not seem like it is though.
Wanna see that Antenna! Definitely! Nice Challenge! First of all because I can‘t do something like this I would like to see you trying this!

I love the way he conned his buddy to get a free beer.
"Can I borrow your phone? Mine has a dead battery."
"I kinda think it's beer o'clock, do you want a beer?"
Alright, free beer!
Yeah, then he's the 'generous friend' asking the guy who's paying for everything if he want anything. ;)
Dude is properly Chinese now. Back when I was in primary school in Beijing, we'd always say things like "can I borrow a piece of paper" or "can I borrow your eraser"? The papers are never returned, obviously. And the erasers are returned after we use it for a bit, meaning it's not "returned in full"-- just like his buddy's phone wallet was returned with a little bit of money gone.
Checked Chinese news, 兔兔到家 (the name of the cashierless shop), seems to be an indie/small group/startup operation that launched the shop from around 2017 but probably spent years in developing all the tech. Dont know how well its doing because its pretty much unknown on Chinese news except for in Yiwu.
yes，but there are a lot other company setting this kind of shop，like “taocafe”
The store looked empty, especially the fridges. EIther really a hit and needed to refresh stock, or doesn't get much attention and is just empty.
It’s also probably really easy to steal from them. You just buy something cheap, open the door and have your buddy run in and grab all the drinks.
@@zmaxx21 I am pretty sure they have scans near the door to spot unpaid goods and surveillance cameras inside the store so police can find you easily.
I live in China and often travel to tier 1-2-3 cities and villages for my work. There are only a few such stores in China. The government does not like promoting anything that reduces employment. QED.
What it does not mind doing however is allowing such companies to trial their products in Chinese cities (beta testing) so that they can then export them to developed western nations that wish to replace humans in stores (or don't have people for it). Australia, USA, Scandinavian remote regions...
For example, Shenzhen, a hi tech city where you only see pure electric scooters on the pavements and roads, and where nearly all our street lights are solar powered LED, and 20% of the buses are electric, where most people make smaller payments using wechat bar codes (on their smart phones), there are just a handful of such stores. I havent even seen a single such store in Nanshan, even thoug there are tens of thousands of convenience stores and shops.
I worked with RFID in the Late 1990s. The supplier I worked with was bought by Hughes ID (HID). They used standard HP inkjet ink to print paper tags for a project that we did with the Postal service. The standard HP ink jet ink is conductive enough to make a good antenna.
For real
I've even wanted to build my own tags in the past, that would be so cool!
In a Spanish clothing shop, they use also rfid on every label price. but the coolest thing is, they have a device what can find the location of the tag. in other words, they can find thiefs even outside of the store and also its easier after shops closed to find all laying around clothes and hang these back to the belonging places.
Christian Schnitt what is the maximum distance you have been able to read one? I'm wanting to work on an experiment to see if I can make a very sensitive antenna to pick up lost pets RF chip. It would be awesome just to reach 200 feet
This is interesting. I’ve just found out that Uniqlo now are using rfid tags on every label. At first i dont know whats the function of these rfid tags that they put on the label. Wow. Do they really able to locate the location of the item eventho they are outside the shops? Thats crazy.
+
outside but not far away.like sony tags does
Same here in Finland, in my local grocery store they put those rfid stickers on some seemingly random, and usually low value products. I guess those are the most commonly stolen items.
So it's like a walk in vending machine.
Which is basically a (non-food) automat, if you're old!
just a suggestion. Maybe you should trade mark the name. 🤪
Exactly my thought too! That’s a good name actually
looks like an al you can eat buffet to me lol
@@oldskoolhead0 gets locked in* i guess you can smash the door but you also scanned your phone and in china phones are tied to your "social security" card so they can find you pretty easily probably
That concept in its entirety is mad brilliant. If you could integrate RFID or NFC into the packaging, you could almost completely automate an American convenience store. You might have to have one or two employees for a 7 Eleven or Lawson scale store in order to maintain shelves authorize alcohol, tobacco, and gasoline sales, but it would make management and operation of them way easier. I could totally get behind this business model.
Honestly, all the videos that are on this channel make me interested in things I never would have cared about before. The way they’re presented is fantastic. I love the down to earth way you go about things and the way you are obviously excited about everything you come across. Keep it up 👍
Thank you for this episode. When I saw that store in Colin's Yiwu video, I was very curious about it, and hoped you would talk about it in a future episode.
The RFID-tag does not transmit anything. You saw how it loaded down the transmitter on the frequency sweep he did on the miniVNA? RFID-tags communicate by modulating how much it's loading the transmitter. Say you have a small transmitter at 850 MHz and the chip gets near and loads down the transmitter. This can be detected in the power usage in the transmitter. The tag will modulate (morse code, on/off, just WAY more complicated) and the power usage figure is decoded and data comes out :)
That made hell a lot more sense than a tiny chip being able to both work and *somehow* gather enough power to rebroadcast. Thanks.
It's kind of like doing a side-channel attack, but it's the intended way of communicating with it :)
Get the comment up to the top. everyone like it.
You are describing an NFC (near field communication) chip read process. There the item needs to be placed very close, almost touching, the reader.
This was an UHF RFID chip (completely different wavelength range), that can be read from meters away. It diffracts (reflects with alteration) back the signal it gets from the reader, and that's what the reader picks up. So it actually does send a response, not just cause a "disturbance in the Force" like in NFC.
"Surrounded by computers and browsing a smartphone." - One of the most brilliant quotes on this entire channel, hats off to him.
Man, technology has come a long way. Who would have thought, say 50 years ago, that we would be able to have a cashier-less store and paper-thin, passively-powered tags that can be scanned by just being near the counter.
Am I the only one who wants copies of the cool vintage posters?
did you find any hints where they are from?
Oh it's you... gr8... (btw, your vids are terrible. I hope you're learning from this guy ;) ).
They are from the National Safety Council, but I have no luck so far in finding a source that ships outside of the USA
There's always Borderlinx for that.
Wow. You're here as well.
"Surrounded by computers and browsing from smartphone"
haha, good one! :)
So cool!! I cant wait to go to China one day! You always show such cool stuff in your videos.
I'm so glad Scotty is doing these videos. If you look around UA-cam, most people are just making videos about the worst things they can find in China to complain about for the bandwagon views. When I visited China it was extremely friendly towards Westerners and my only complaint is about the cigarette concentration, but that is also going down.

Wait, so now we are reverse engineering chinese made products to see how they are made? Cool!
Lol
That thing started years ago. Eg, Amazo/ delivery service. Mail boxes. Apple Pay. Let’s just say that business model is shared to all human beings.
BigCliveDotcom is doing this for years, actually :P. Up to the point that watching some of his cheap Chinese USB chargers he got sent to from viewers has made me incredibly cautious about seeing people using them and without any reluctance handling their metal-cased phone....
Something called copyright
People have already been using this. UA-camrs are just pretending for hype
Alibaba and taobao is such a thing where I went to buy stepper motors and ended up buying a giant and expensive microscope.
BwaHaHaaa the dangers of chinese shopping. Now I need a warehouse for all my goodies... :-)
Christian von Delius if you are buying development boards (arduino, espruino, etc) or LCD panels it is perfect for that. But then you start buying big RFID readers, genuine security cameras (when it arrives first thing to do is install Dahua firmware to it and change password) and stuff like connectors or terminal blocks it goes too far. Then you discover things like RuiDeng power supply modules (only place they sell them) that are worth their money. Then you come across a Andonstar ADSM302 with free DHL shipping and you have no choice to buy it.
@@felenov So is Alibaba & Taobao better than Aliexpress? I have noticed the price of electronics keep going up and up and up on Aliexpress, my guess is simply because they can, because people will pay it. Are the prices on Alibaba & Taobao more reasonable than Aliexpress these days?
@@skins4thewin Sellers love playing with the prices. They raise the price and discount it. Or the moment the sale starts, prices go through the roof. So be careful and watch the prices, then you will be good. Also asking the seller to give more information about the product sometimes gets you a lower price
@@felenov Hm, I have only seen prices get raised from what I have seen, but perhaps that is due to the types of products I look for, which is mainly electronics and video game related items. I suppose because Americans are willing to pay more for them they feel they can raise the prices accordingly. Shame to hear that about prices going up during sales, that's a shame.
Either way, do you think that either Alibaba or Taobao has better value than a place like Aliexpress? Am just curious.
Durian in Southeast Asia is popular and delicious
I agree with the first of your two statements:)
Fikri Rizaldi Kamil durianrider?
Durian is awesomeeeeeee
Fikri Rizaldi Kamil I don't know I tried ice-cream not the fruit by itself in China, it's not as bad as they make it look but I'm not a fan and can think of many delicious fruit.....it tastes bad...
Durian taste bad
This is cool, I guess. But I don't see why they don't just have a standard barcode scanning machine. Cheaper and no waste.
My guess is they use rfid because it's more thief proof than Barcode. Because with barcode you can scan cheap items but you actually bring out an expensive one. Or You can even go out without even paying anything.
Bar codes dont have the ability to send information back to the reader. As far as swapping RFID tags with a lower-priced product, there are ways to verify if something has been tampered with. Such as using a product's weight as verification. Many self-checkout systems (in the USA) use this method to catch would-be bar-code swappers. This is why after scanning an item, you usually have to place the item in the bagging area (which serves as a scale) so that the added weight can be checked against the known weight of each item.
They may also use a camera to make sure the product visually matches the product reported by the RFID tag
Wow. China is beating amazon to the punch. A bit different from amazons concept tho
Would the door not open if you had anything that wasn't paid for?
Unnamed Review Guy if you also not buy anything u can scan the qrcode behind the door
Unnamed Review Guy China still has a lot of high technology but many Foreigners don't know that China is a big innovator. China's rise has been unstoppable, and that is the trade war America has waged against China. America is bound to lose this trade war.
Amazon's method is over the top. Using expensive AI and cameras to know what you pick up lmao. Even then it only works for certain items
That’s when the lasers come out.
I actually tried just that and yea as someone else said, just scan the QR code next to the door
Those are called "UHF RFID Tags". The tranceiver is capable of reading muptiple tags at once. That means that you could have placed those items on a cash register in the shop at once (like in a shopping bag) and it would read all of them at once without a problem.
I remember reading an article several years ago that Walmart was actively researching options to attach tags to all retail products but they need the price of the tag technology to less than $0.01 per tag to meet their business demands. Also recently received a pair of Five Ten sneakers owned by ADIDAS company. When I was removing the cardboard paper tag from one of the shoes and noticed the paper splitting I discovered this same type of tag was sandwiched inside. So of course I rinsed off all the cardboard paper fivers from the sticky film the antenna and chip was attached to and wound up wit someone very closely to what you have. At fist I though it was a loss prevention tag but I now think its more an asset ID tag for contactless inventory and next gen POS purposes.
Great video and god I bet that durian ice cream pop was interesting! LOL
55 cashiers didnt like the video
In USA if there would have been put a similar one there it would not have been broken into or hacked into, the whole store would just have been plain stolen.
dtiydr there is though here in Seattle (Amazon), and it's significantly more high tech than this one.
Amazon is most likely collecting data for itself with all that tech.
It is actually nice that Chinese society apparently has this level of integrity that this system will work. Sad note on American society that I agree with your comment.
Amazon Go primarily relies on computer vision (and scales). Amusingly enough, the company that makes these RFID chips (Impinj) is located next to Amazon's headquarters.
I assume Amazon Go relies somewhat on crowdsourced verification of their computer vision analysis (via something like MTurk), so there's probably still some humans in the loop. The real question is whether computer vision (with human augmentation as needed) will end up being cheaper than putting a tag on each item. But with tags on everything, you can get more benefits: a fridge that knows expiration dates and potential product recalls of everything inside, automated recycling sorting, seamless returns based on the unique ID of the tag, etc.
awesomeferret actually Alibaba group, giant company just like Amazon in Asia. They have 20 outlets without cashier just like the only Amazon Go in Seattle. JD.ID X , first AI based supermarket in Asia outside China in Jakarta, Indonesia. I’m an Indonesian and surprisingly JD.ID X sells stuffs with the same price like other normal supermarket and even cheaper for special deals. You don’t even need to scan or put the groceries on the scanner just walk and confirm your face.
What is even more cool is that 2 beers and a bottle of water only cost £1.74!
Amazing
So I just started working for a company called Triple Crown, im a technical recruiter and I have learned so much about what you do and enjoy this channel even more now than before. I just spent all day looking for an rfic design engineer with mmwave experience. You should do a video on that, mmwave tech.
Not really an apple fan myself, but I must say your character is so energetic that I love to watch every video of yours! Keep up the good work, it is highly informing and I already learned so much from you!
It's just conductive ink antenna. You can get conductive ink for your printer and even for 3D printers.
"It's not that hard"...... 😜🤣🤣 I love your optimism. 😂😂😂 I'd like to see your antenna results. Or rather your bumbling and stumbling into a sort of working results 🤓🤣👍
Great video man. Thanks for sharing.
I am interested how they stop theft because if you just took off the sticker and left it in the store and took the item how would they stop you?
I think there are probably cameras as well, but don't remember offhand. Petty theft like this doesn't seem to be as prominent here as a lot of other places I've been. Not to say it doesn't happen, but it happens a lot less as far as I can tell. So things can be more relaxed without it being a huge problem. For instance, I see bicycles and ebikes all the time that are just locked with a simple chain through the rear wheel...
Strange Parts good to know. England is worse
There were cameras outside and inside in the corners. The ones inside look like the type of dome cameras that can be remotely moved with zoom etc
Darkskynet I suppose there will be security watching live then
maybe in the walls near the door they have another RFID reader that verifies that the data it reads match exactly with that of a recent purchase made...you know like guards outside malls do! just a guess
Your channel is so cool.
Your energy and attitude are a joy to watch. Thanks for all you do!
I've taken apart exact RFID stickers like that from cell phone accessories (likely from China) YEARS ago. Like 8-9 years ago at least. I don't remember if the chip was that small. I didn't analyse it as well as you did. The antenna was identical though. They also sell those antennas to stick on your phone to "boost reception". Cool tech. Thanks for the video
Hell yes to more RFID. Maybe even get one implanted. I have two and they're great for hacking. One even works with the local hackerspace door access system.
China is more advanced than i anticipated,that's really cool.
@Brandy Wasay yeah bro all those inovations out of china are foriegns all 1000's of them big and small
Nah, Chinese just too greedy to pay to shop keepers, so they use available technology to cut costs.
Brandy Wasay no, the majority foreigners works in china as English teacher or reporters, don’t be salty just becuz others have better technology and living conditions than u do.
@@blackricejam8984 yeah right.......
@Brandy Wasay Keep thinking like that and spread this to the world especially USA.The Chinese will very much appreciate you.
well, they could sell 100 through hole transistor for a dollar and thats including shipping cost.

pee flavored ice-cream, thats some astronaut level stuff XD
PEA I think, but food for thought! HAHA

it is just the durian flaver icecream
Durian either tastes like custard or rancid farts, depending on who you are and how your taste buds work.
What if your phone battery runs out inside the store
maybe it has a motion sensor, so it opens any time someone comes close, except if they're carrying something that was not paid for.
Yeah, I was thinking the same. I think there was another QR code for you if you weren't buying anything. I may be wrong, but I was thinking about what if there was a power cut, and you'd be locked inside
Good point. The mere hypothesis gets me out of breath... haha
Slap a tag on your head and hope whoever buys you is nice.
Just borrow your friends and make them pay for everything XD
They need somebody to keep an inventory of stock and stack shelves and to set prices for the items in the system also label prices on items and notify customers of offers as well as to keep the premises clean
+Strange Earth, the RFID stickers are made with printed Silver Chloride. There's a company based in San Rafael, California called Byte Foods that sets up mini refrigerators in offices and lunch rooms that sell food.
it's so nice to see some plants right outside your office...looks relaxing.
THIS IS SO COOL!!!
Awesome no need to talk to the cashier :)
“It’s not that hard” tell that to my electrical engineer buddies 😂😂😂

我也想来参观可以吗？
Dji won't be happy then 🚁💔
Cant wait to see that!!!!!!
Now, do a fight: Durian vs Surströmming!
Woah, calm down satan.
Those stickers look like UHF RFID tags (UHF can have pretty huge read ranges). They come in an insane variety of antenna shapes and ICs (depending if you want read only, or user writable data, or even onboard sensors if you want active tags).
The copper coil ones however (like tap cards) are probably LF or HF RFID. They aren't designed for longer range reads (because you only want to read at a close proximity).
Where I work every piece of clothing has an RFID tag and we use that to perform stock takes really easily. What used to take a whole team of 10+ people an entire day to complete now takes two people an hour. This means stock takes can now be done weekly instead of yearly.
We don't use the RFID for selling but I guess we will see what the future holds.
any chance of exploring an e-reader/e-ink factory, like the screens made for kindle or kobo (lots on Alibaba, would be cool to see if company photos are real or fake as well)

And lol that Durian ice cream...WTF, apparently the fruit is not allowed on public transport etc cause it stinks.
Vipps in Norway; the only place I still have to use a card to pay is in the local grocery store and Burger King who both signed up with a competitor that went out of business. Ideally I'll have an app on my watch soon so I don't have to bring my phone either.
More info on these types of tags:
-cost is fractions of cents (typically 0,1c), so well adapted to convenience store items
-the frequency they work at is typically 866, 916 or 920 MHz, close to GSM frequencies which allow for more efficient antenna within the available volume
-typically, the chip is very simple and just sends an identification number back
-they can be read from a distance of a meter (or more depending on the reader), so I suppose that there is a reader at the exit to check that the customer does not take extra items out
-the latter is probably the reason for the QR code scan: the customer is identified when coming in. At the exit, the system checks what is near the exit reader: a phone and a collection of tags. If the two do not match the bought items, the door would not open, I suppose. Presumably, they use near field communication on the phone to insure positioning within that volume.
I LOVE WHAT YOU DO, Please don;t stop! I can,t be there in China so, you bring me closer to that country with each of your videos, THANKS my friend.
Whats to stop someone paying for the cheapest item and ripping off the tags and stealing a heap of other items? Is it an honesty system or is there other types of security?
When you scan yourself IN to open the door, they know who you are, cameras get activated in the shop, etc. So It'd be pretty tightly monitored.
in china ur citizen id is tied to phone and apps. skynet and social credit system crazy stuff lol
besides all the Skynet and other crazy stuff, manless shops make sense as long as the system is good enough to keep the lost on shoplifting less than hiring a cashier
It's not very hard for someone to stealthly sneak a tag off of the item you take and put it on another item on the shelves, and then keep that out of the camera's line of sight, they won't know you took a extra item, and can't prove it in theory since the tag is still in the shop, plus their system doesn't alert them of shoplifting of removed tags if said unpaid tag does not go anywhere near the door.
Remember that all systems can't be fool proofed, unless you weld the tags to said items so it's not removable, OR hide it on said product so one would not know where to look to remove it..
Unless the scanning platform also weighs your products on the sly and bills you for the rest later. :-)
Watching this, only one thing comes to my mind: My country Ghana and the entire African continent need to abandon our current educational system and adopt new ones that relates to practicals and creativity. How do you teach physics and the sciences at universities and import wheel-barrows? How do you teach wood technology in schools and import tooth picks? How do you teach all engineering course and yet all our roads are built by foreigners? God help me
South Africa has the same issue. The current president is gushing about the 4th Industrial Revolution benefits to the country, but doesn't take into account that a basic thing like electricity can go out at the drop of a dime. The basics aren't even properly in place, and they are already jumping over the intermediate to the advanced level of technology. For a person that is hungry and has no smartphone; of what use is free municipal wifi to that person? o.0
Yeah right, you try that where i live and the store is empty in no time.. And not in the good way.
It was fun to see how RFID tags really look. My local library (in Shenzhen China) has been using them for a few years now.
I saw a similar unmanned store in Quanzhou (Fujian) last year. Fun fact - Very few Chinese people were using it! They were all using the manned convenience store located opposite to it instead.
Not seen any such shops in Shenzhen, but there are two such cabinets below my building with small conveniences like small milk cartons and drinks - both work on a similar principle, but using wechat.
I think the Chinese are making them and beta testing them in Chinese cities, so that they can export them to developed countries where people enjoy the idea of employing fewer people (low overheads, low prices).
A bit like Luck in coffee's unmanned coffee stands.

Perhaps so ... I do not fear the BEAST .... yet.
Is so funny Stuart saying "Oh, you should make your own antenna....." Like how you actually explain the process you are going through. Makes me think of the phrase. "Inquiring minds want to know...."
Passive RFID stickers are just an antenna and small wire that creates a resonance. They have no chip exactly. That strip in the middle is just a tuner essentially. Whereas active RFID are actually inductive coupling (wireless charging) devices for power that interrupt the coupling to send information back and forth. These have microchips and are reprogramable.
Superb

Does it occur to you.. what is the purpose to open a self service shop in a country with over a billion ppl? Doesn't it create an imbalance of economy, if u have a shop u expect to sell goods to ppl for money, but on the flip side, ppl need to sell labor for money also. Jobs is in direct proportion to economic output/sustainability
Damn thats super cheap, those things all together only cost him around 12 cents
so happy to see so many talented guy in China doing things they like.
There are two kinds of RFID each differ by their mode of operations. (1) Near field magnetic coupled method uses close loop induction running at hundreds of kHz, are less complicated and easier to develop and (2) far field electromagnetic radiative method uses open loop (dipole or its derivative) induction, very small yet complicated quite difficult to develop successfully.
For near field type the range is 10cm max very low cost and high volume, while far field type range is 10m or so and relative expensive.
The one in this video is dipole coupled type.
