The fact that this man has a magnifying glass and used it to actually zoom up rather than showing a completely blurry close up is worth a thumbs up alone
Thanks for this Julian. This is helping me write a security system for my home where a person would scan an RFID tag to turn off the security features... while it is still all in the future: alarm, facial recognition and video documentation. This is all a hobby at this point, I'm just loving coming up with solutions for problems I want to crack.
I built a Dalek once using RFID to identify it's master and guests. It had an airsoft cannon to pelt those who didn't "Identify" properly. It used a Raspberry Pi SBC for a main brain, an old Xbox Kinect for it's eyes and ears, and a bunch of micro-controllers for it's peripheral control systems.
We have started to use them on our project: Automated Library Management System, wherein we would be using the tags for identifying book, tracking, security checks, smooth technical processing of the books, easy to locate books in library and also certain membership management techniques for library users.
The Dutch people who cracked it actually cracked the public transit card system by overwriting the cards with information about credit for public transit.
Just randomly popped up in my recommended. I'm using this exact setup in my engineering class so thanks for the help. You probably just got me an A on my final.
Thanks for that informative presentation. My own interest is to clone the RFID fob I have for entry into my apartment (which I've been informed will cost £60 if lost - apparently they need to "send an engineer" - lol).
better find where a controller is in your appartment. determine the model, find the manual, reset it to factory defaults, and program your own cards into it. you will end up with a master card which can be used to teach our own cards as regular entry keys. the master card or any teached in regular cards of your landlord will no longer work :) no extra hardware is required besides a couple of extra compatible cards. do not forget to give your new master card to your landlord after you end the rent.
I bought a bunch of those blue RFID tags for my alarm system. Originally they were fine but over time they become very weak. You have to touch the alarm receiver in a very exact spot and with the flat side of the tag, otherwise it just won't work. Meanwhile the original tag (grey block) supplied with the alarm works fine. There's something definitely iffy about these blue ones.
This was one of the most concise and informative videos I've found on the use and management of these devices. It's given me a great first step and pointed me in the right direction to find out more. Thanks mate.
Well you could use it for hidden doors or something like that - you could just put the electronics inside something - you could also add those rf-relay-buttons to it so you could control anything with it - youd need a way to power it tho
Is this for low or high frequency? Does it store data on it like the r.f.i.d. used for pets? Can you erase the radio frequency? How. Can I disable it to not give a signal?
I would love a video that explains how to install one these say in a vehicle. Like the new cars that have the chip in the key. You could set the reader near the keys and only allow the car to start if the chip is in proximity. It sounds like a fun project and it could potentially keep your car a little safer from theft. If you really wanted to get clever you could install it on the power supply for the fuel pump rather then the ignition and place the reader under a cup holder or something so if you were parking your car in a bad area all you have to do is grab the chip outta the cup holder to disable the fuel pump. Just thinking out loud here but I could think of all kinds of fun things to do with rfid if it wasn't so complicated to set-up.
Julian, there are hundreds of uses for RFID tags, like for instance, chipping pets, (these are tiny glass capsules which are placed in the neck of a dog or a cat or other animals, and the chip ID can be read and pets are registered on a data base, so when lost and found they can be reunited with their owners, you could use them on cat flaps that reads the chip of your pet and only allows it the access to come into the house and other animals are denied access. You could mark your property, etc etc, I understand that such technology will be implemented on supermarket items such that a reader will read all the items in your trolley and produce a bill that you simply pay and walk out without having to take items out of your trolley on to a supermarket conveyor belt for scanning individual product.
Large retailers already use RFID for garment stock control. They can identify each garment as it comes in the back door and when sold. They can also tell if it gets nicked...
Uses of RFID ( i dont know how many of are implemented), If you got any ideas feel free to add them as replys. 1. Package tracking. 2. Access control. 3. To store product info in package replacing barcode 4. Store indoor/outdoor location information such as lobby, stairs, elevator which can be used by blind and other disabled people. Put the cards/tags in location and a reader in cane/wheelchair will read it. 5. Pet control, get some RFID tags and install RFID reader in kitchen door to keep them away from kitchen, If you dont like pets in kitchen.
Since you asked at the end of the video, you could use one of those to generate a grocery list if you hook it up inside your fridge. Then just write the information (name, type, expiry) and have it attached to the object so when it expires or is out of the fridge for a certain amount of time it would write it on a digital list for you to take to the grocery store. Even make it more advanced and have it search your fridge for ingredients when you find a recipe you want to make so you know If you have everything required!
Another idea I just had was if you felt like doing an air quality experiment but didn't feel like creating a webserver to compile the data to you could use a USB with a reader on it to read all your different stations and have them logged in that way.
Another really useful video. I too had a play with various cheap RFID, including the RC522. But in the end I settled on a PN532 based card, which is little more expensive, as it has compatibility with a greater range of tags, including NFC. Need more time to play with it though.
Saw it on Seller alice1101983 and I do have it in my cart. Thanks for the short tutorial about it. As you said what to use it for other than the intended use. Put it on the bottom of a cup and data log your drinking habits. My first project with it is to datalog my life. Cheers
I don't understand half of what I watched, but somehow I kept watching. Now at least I am more informed on RFIDs. Did not know they had a coil and chip inside them.
Haha! I just got these to play with as well. Got it all working and thought the same thing: I don’t know what I would practically use it for…. Thanks for the video!
spent ages trying to get one of these working in conjunction with a data logging RTC/SD shield on a nano, both communicating over SPI. Turns out it doesn't have tri-state IO. When CS is high (chip disabled), it won't let any other device use the MISO line. Took hours to fault find this!! You'd expect an implementation of SPI to be able to share lines. Surely that's the whole point of SPI! Can't spare anymore IO on the Nano so going to have to try multiplexing the MISO line with a dedicated chip.
Thanks for this extremely useful video! I've bought it with actually no clue on how to get it working, but now that i've seen your video i have much clearer information on how to use it! Thanks a lot. :)
Just a note. "SDA" is the nomenclature of I2C communications which uses SDA, SCL, VCC and GND. It is another type of communications used by Arduino and Raspberry Pi. en.wikipedia.org/wiki/I²C.
I have one of those inexpensive RC-522 readers. While it reads the card and the keychain thingy that came with the package just fine, I can't really get it to work with other mifare cards (both 1k and 4k cards, and yes I'm sure they're mifare). I've done a lot of experimentation with the library from miguelbalboa, like trying to change the receiver gain registers and the pmos and nmos conductance, but no success yet. Perhaps the supporting electronics to connect the RC-522 chip to the reader/writer coil is not up to specification, or perhaps even the RC-522 chip is fake? So, I guess you get what you pay for...
I had the same thought (but for the commute here in sweden), but i think they use a custom fequency and an advanced cryption system... But it would be fun to just read a card to see :)
Björn Camitz Oyster cards used in London once used the chips mentioned, they had to change them quick I think!! I guess the magic really is in the encryption as you can still buy the chips the new cards use or so I understood although it is hard for me to figure out.
Knuckles the Echidna The difference has become a sort of segregation of what operating frequency the card uses. 125kHz is used in older RFID/HID cards whereas the 13.56MHz MFC/MIFARE cards are the standard being used for NFC/Google Wallet/Apple Pay/Eurocards. Otherwise they are one and the same; contactless card reading/writing systems.
Probably some body has changed the default authentication password of those cards. RFID tags are very durable, normal usage wouldn't corrupt anything unless you have changed the authentication passwords to something you cannot remember or accidentally sent the kill command(some tags other than mifare support the kill command.)
or maybe those cards are not mifare types. common ISO14443A/B cards are more widely used in access control. mifare are mostly used when values like money need to be stored , like bus passes
can you actually Write on cards that have a RFID code on it? example: i have a RFID card with a LOGIN NUMBER on it, and you hold it to a machine and then you need to give the password. but the problem is i lost a card which i know the LOGIN NUMBER, but if i wanna get a new card, because i lost my old one, i need to pay 30$...so i wanna know CAN I TAKE A RFID CARD, delete the internal LOGIN NUMBER and PUT a other one on it with this device? thx
that's totally depends. you also need to know where to store your data, and the original data might be encrypted in some form. And for some applications, people dont really write the actual data to the cards. Instead, they only use the tag id(UID), and then link the tag id to the data which has been placed in a more secured database.
Hi,Thanks for your video , I have a question about tags! does each RFID system has own tags I mean every company writes own data to tags and it can not be understand by others?
Are there any routines for the Raspberry Pi and this module? Want to put together the RFID, camera and put it on a MESH system for local events where our ARES group is supporting them.
my RFID/NFC project is for Scalextric Digital slot car racing. The Race Management Software needed a faster way to assign a car to a 'lane' and a driver to a lane. With an RFID sticker tag in the inside of every car and hand throttle, and each driver having an RFID card, the race setup process can be made a lot faster. Scalextric... it was never really for kids!
This is interesting! Im planning to make an adoptation of this tech to our shared laundry room at my landlords houses. Or maybe some totaly unecessary stuff like a RFID startbutton to an old PC.
You can use it as a Time Clock like punching in for doing your hourly work punching out taking a break and be able to start your data out of that way you can just download it and basically they're just for the month or the week or whatever
Hey there, Just wondering if you have considered using a screen recording program instead of a handheld camera? It would be a nicer viewing experience IMO.
i need read some information from a rfid card but i have the same problem the UID is good but PCD_Authenticate() failed: Timeout in communication. lik this 5:54 what is the solution ?
sure it works, but if you can code your own routines, you'll have more control and exactly the functions you want these days, many good resources for RFID on both ends. best thing is they are still inexpensive devices with free software if you do a little searching
Great video. I've worked with the exact same modules, but because their range is extremely low, I couldn't use them for my project. And at the end, you say it's complicated! Huh? These chips has lots and lots of awesome features. For example if you take multiple cards or tags close to it simultaneously, you can get the list of all of them and then decide which one do you want to communicate with. Or you can pace two modules in front of each other and have a wireless connection using NFC. Now, those are complicated buddy!
_re: not sure what to use it for._ i have (eventual) plans on using it to automatically sense when the phone is docked into my smartphone robot. Perhaps even automatically pick up the phone and dock itself, if you simply put the phone nearby (it'd trigger a search routine). Sortof like a robot comically trying to reattach it's own severed head. One cool thing i've seen is people using RFID tags with cutting edge prosthetic arms. They put sticker-tags all around their house and the reader is in the arm, it tells the arm what context it's in. ie: There's a tag on the fridge door which automatically sets the fingers to "open the fridge" mode, one in the bathroom to set it to "hold toothbrush" mode. Handy stuff like that.
Link in description please! :) I'm not too lazy to watch the video and look it up myself, but it would be nice to know exactly which one you've used. Great video! Thanks
Hello! Do you need the keys to read/write the cards or the tags?? or you can just override any data between sector 1 and sector 15?? thank you from Argentina!!
Where can I download the library files? I tried with rfidmaster, it works but i can't find any info on it so i used example sketches and the miguelbalboa/rfid library looks better. I also noticed that the module must be powered via 3.3v but it accepts 5V SPI signals and the SS pin is labeled SDA on certain modules because the RC522 chip can be used with an I2C interface.
i want to make an electric door lock and as key, use my own costume card. this project is for the library of the school so the keys will be the student id cards. i have been asking everyone in school if they know what kind of card it is and no one knows. i have done the the technique in 2:14 and the internal circuit of my student id card looks pretty much the same. does that mean that i should use a rfid rc522 with the frequency of 13.56 MHz ?
Thinking of getting a receiver module for GM keyless entry (like my Cadillac CTS uses) then , when I sit down at my computer it will unlock automatically using my car’s keyfob without having to remove my car keys from my pocket-get tired of typing in passwords
Howsit guys. Any idea whats the read range with the credit card sized tag. I intend on implementing an RFID into my final year mechatronics project which requires a read ranged of 1 meter.
Hello good afternoon, I really need your help, how do I write numbers with decimal places in the memory card. I write whole numbers 1,2,3,4,5 type using mfrc522.MIFARE_Decrement (valueBlockA, value), but record with decimal places no type 1:50, 2:50, 3:50 can not. I am very grateful if you can help me.
Would you go into detail while using known key and blocking unknown keys. I can't seem to get any of my RFID tags to work even with the default program after removing factory default (FF).
This RC522 module seems to be pretty inconsistent. The more expensive PN532 based modules seem to read all sorts of cards/keychains/stickers just fine, including a card that was originally included in the RC522 package, but which the RC522 itself couldn't read...
Hi, I'm a begginer whith Arduino, I have a RFID-RC522 and playng playng I screwed it up, now my card gives me error law normally to range 2 and then me error 1 7 PCD_Autenticate () failed: Timeout in communication. 0 3 PCD_Autenticate () failed: Timeout in communication. there way to solve? thank you
About the compromised crypto, the guys doing it were PhDs, postdocs and researchers, with Bart Jacobs being the head professor. I worked at the same department two doors away from them. COincidently, the manufacturer NXP was from in the same city of Nijmegen. The whole (partly political) aftermath was 'interesting'. The group was at least capable of cloning access control chips, public transport chipcards and putting their public transport cards onto some spare sector of their passports etc. Fun times they were!
One idea: Windows supports smartcard/RFID authentication. I don't know much about it, but you can require the presence of such a device to log in. With encrypted directories/drives it can make for an effective two-factor security system.
can this be powered by a mini 3.7v 75mah batt? if so... where would one attach it? I figured an SD card would be needed unless there was a way to also send the reads remotely to a server/pc.
Incase you still need it... the server part can be handled by an esp8266. a stand-alone wifi module. what you do with the data from the server is upto your application but yeah it's possible and easy . depends on the current requirements... 3.7 volts should be fine but the 75 mAh capacity might only last you an hour !! again depending on current draws. there are deep sleep modes for the Arduino and the esp so meticulous programming will give you a better life. ( upto a few years depending on the number of times you want it to wake up)
Is there a follow-up video to this one? I just bought a 100 pack of cards and several readers I want to make ap roject out of. I want to try and use it to play a trading card game with another player over the internet using real cards and a placemat with readers embedded in it
i read elsewhere that level shifter are needed to use this board with arduino, because not all of the mifare are 5v tolerant, and the board itself is 3.3v... any info about this? thanks
Very informative video. Would you happen to know if this device would read chips used for pet identification? One such chip is the ALLFLEX ISO FDX-B transponder. Thank you, Eric
I'm using Arduino Pro Micro to connect to Mifare RFID reader. I have connected everything but not sure what's the Pin number of the RST to write in code. Here's the definition... * RST/Reset RST 9 5 D9 RESET/ICSP-5 RST In RFID_DumpInfo program, and when I use Arduino Uno I used #define RST_PIN 9 BUT what should I define it when using Pro Micro? What's the RST pin number in Pro Micro?
Hi freind,This is grace from Greenrfid company,we are a card manufacturer in Shenzhen China.we can provide all kind of card to you. My Email is grace@greenrfid.com or leave your contact information.let's talk details.
Funny that they published the paper of de encryption (hack) study done in Holland. When everything transportation went digital in Holland, it automatically became a target for hackers. It was published in a computer magazine how it was done as well.
You seem to know quite a bit about RFID and such. At work we have an door with a key pad. I'm pretty sure it reads RFID as well. I think my question is about the frequency of these things. They are not al on the same RF freq. Will these readers be able to get the frequency from the door and be able to write the access pin onto the card? do they make separate cards for each frequency? I don't know enough to even formulate the proper question. I would probably need to have the frequency the door keypads receives before I would go out and purchase a reader/writer, cards/chips?
The fact that this man has a magnifying glass and used it to actually zoom up rather than showing a completely blurry close up is worth a thumbs up alone

The balance information was saved on the chipkaart instead of on a central server?
@@abnormaalz yes
Its flexibility in managing many tags as well as making it an ideal choice for applications that require real-time data management.

+Julian Ilett How can I deactivate a RFID chip?
You can't. There is no such "deactivation" in RFID Devices.
Disclosurer Radio Shouldn't reprogramming the chip with the wrong data accomplish your needs?
cut it in half lmao
love how you were able to show sources as to where you found each information step by step. A very helpful video. thank you
Well you could use it for hidden doors or something like that - you could just put the electronics inside something - you could also add those rf-relay-buttons to it so you could control anything with it - youd need a way to power it tho
9v battery
Is this for low or high frequency?
Does it store data on it like the r.f.i.d. used for pets?
Can you erase the radio frequency?
How. Can I disable it to not give a signal?

You think they're going to put RFID tags on every banana ever sold?
Sure. They put stickers on all fruits now anyway. Why not a low cost RFID sticker just like the ones they put on other packages?
Skub Berson it’s not needed
Large retailers already use RFID for garment stock control. They can identify each garment as it comes in the back door and when sold. They can also tell if it gets nicked...
Uses of RFID ( i dont know how many of are implemented), If you got any ideas feel free to add them as replys.
1. Package tracking.
2. Access control.
3. To store product info in package replacing barcode
4. Store indoor/outdoor location information such as lobby, stairs, elevator which can be used by blind and other disabled people. Put the cards/tags in location and a reader in cane/wheelchair will read it.
5. Pet control, get some RFID tags and install RFID reader in kitchen door to keep them away from kitchen, If you dont like pets in kitchen.

+Ger Lagerweij he can write assembly, so I would hope he knows what he's doing.
Any chance you can lets us know how many volts are generated in the tag coil when its put close to the reader please?
i need read some information from a rfid card but i have the same problem the UID is good but PCD_Authenticate() failed: Timeout in communication. lik this 5:54 what is the solution ?
Julian, could you please attempt to get IRQ Interrupts working on this module and make a video about it? Thanks
sure it works, but if you can code your own routines, you'll have more control and exactly the functions you want
these days, many good resources for RFID on both ends. best thing is they are still inexpensive devices with free software if you do a little searching
Great video. I've worked with the exact same modules, but because their range is extremely low, I couldn't use them for my project. And at the end, you say it's complicated! Huh? These chips has lots and lots of awesome features. For example if you take multiple cards or tags close to it simultaneously, you can get the list of all of them and then decide which one do you want to communicate with. Or you can pace two modules in front of each other and have a wireless connection using NFC. Now, those are complicated buddy!
Thank you for sharing this. I plan to try this out on reading microchipped animals for identification purposes.
i tried the same thing with my rfid rc522 but on a esp32 wroover model using pin 21 and 22 but nothing happens...
hi sir, with this device would be able to read a lot kind info RFID with storage data in txt for example , to write another moment ?
so could I read and then write to a blank rfid tag for a HID proxkey? I want to read and maybe even alter the data on my building key card
most impressive instructions, made easier and simple. thank you. I will always keep watching and talking about your videos.
Love this
It helps me know more about it
I wonder if I can use this to replace coin acceptor
_re: not sure what to use it for._
i have (eventual) plans on using it to automatically sense when the phone is docked into my smartphone robot.
Perhaps even automatically pick up the phone and dock itself, if you simply put the phone nearby (it'd trigger a search routine). Sortof like a robot comically trying to reattach it's own severed head.
One cool thing i've seen is people using RFID tags with cutting edge prosthetic arms. They put sticker-tags all around their house and the reader is in the arm, it tells the arm what context it's in. ie: There's a tag on the fridge door which automatically sets the fingers to "open the fridge" mode, one in the bathroom to set it to "hold toothbrush" mode. Handy stuff like that.
Link in description please! :)
I'm not too lazy to watch the video and look it up myself, but it would be nice to know exactly which one you've used. Great video! Thanks
Hello! Do you need the keys to read/write the cards or the tags?? or you can just override any data between sector 1 and sector 15?? thank you from Argentina!!
Where can I download the library files?
I tried with rfidmaster, it works but i can't find any info on it so i used example sketches and the miguelbalboa/rfid library looks better.
I also noticed that the module must be powered via 3.3v but it accepts 5V SPI signals and the SS pin is labeled SDA on certain modules because the RC522 chip can be used with an I2C interface.
+Integrated Electronics Finally it's OK, I found the library from Baidu ("Chinese google")
i want to make an electric door lock and as key, use my own costume card. this project is for the library of the school so the keys will be the student id cards. i have been asking everyone in school if they know what kind of card it is and no one knows. i have done the the technique in 2:14 and the internal circuit of my student id card looks pretty much the same. does that mean that i should use a rfid rc522 with the frequency of 13.56 MHz ?
if anyone knows: would U please answer?
I wonder if the communication problem has something do with the clock mismatch between the Arduino and the tags...?
Can you like where to purchase the other wires and gadgets connected to the reader?
Hello, may i know that is this reader can be used to read uhf rfid strip? it is just for my final project.
Can this detector find the E-thread with RFID chips woven in the clothes.
Thinking of getting a receiver module for GM keyless entry (like my Cadillac CTS uses) then , when I sit down at my computer it will unlock automatically using my car’s keyfob without having to remove my car keys from my pocket-get tired of typing in passwords
The software didnt talk to me when I opened the serial monitor. Its just blank what do I do?
this could be to id and grant access like to TV by using relays and timing there usage. just a thought for a different use
may i ask , did you ever use pn7150 for testing nfc type a / b and other else
Howsit guys. Any idea whats the read range with the credit card sized tag. I intend on implementing an RFID into my final year mechatronics project which requires a read ranged of 1 meter.
17:08
What happened to 0A exactly?
Why's there a FF in it's place?
Please help me out!
Hello good afternoon,
I really need your help, how do I write numbers with decimal places in the memory card. I write whole numbers 1,2,3,4,5 type using mfrc522.MIFARE_Decrement (valueBlockA, value), but record with decimal places no type 1:50, 2:50, 3:50 can not. I am very grateful if you can help me.
you can replace the decimal char by some hex number and do the opposite when you read it.
Would you go into detail while using known key and blocking unknown keys. I can't seem to get any of my RFID tags to work even with the default program after removing factory default (FF).
This RC522 module seems to be pretty inconsistent. The more expensive PN532 based modules seem to read all sorts of cards/keychains/stickers just fine, including a card that was originally included in the RC522 package, but which the RC522 itself couldn't read...
Hi, I'm a begginer whith Arduino, I have a RFID-RC522 and playng playng I screwed it up, now my card gives me error
law normally to range 2 and then me error
1 7 PCD_Autenticate () failed: Timeout in communication.
0 3 PCD_Autenticate () failed: Timeout in communication.
there way to solve?
thank you
About the compromised crypto, the guys doing it were PhDs, postdocs and researchers, with Bart Jacobs being the head professor. I worked at the same department two doors away from them. COincidently, the manufacturer NXP was from in the same city of Nijmegen. The whole (partly political) aftermath was 'interesting'. The group was at least capable of cloning access control chips, public transport chipcards and putting their public transport cards onto some spare sector of their passports etc. Fun times they were!

Why does the GMS tNice tutorialng doesn't soft sa way like it did in the video?
One idea: Windows supports smartcard/RFID authentication. I don't know much about it, but you can require the presence of such a device to log in. With encrypted directories/drives it can make for an effective two-factor security system.
How big are the insides of those tags ? Would I be able to take it apart and put it inside a plastic cell 3cm in diameter ?
It would have been nice if you had supplied the USB Interface device link for this project!
How far can I set the range on the RFID scanner? Does it have to be that close?
Tought Mifare was used in bus smartcards?
can this be powered by a mini 3.7v 75mah batt? if so... where would one attach it? I figured an SD card would be needed unless there was a way to also send the reads remotely to a server/pc.
Incase you still need it... the server part can be handled by an esp8266. a stand-alone wifi module. what you do with the data from the server is upto your application but yeah it's possible and easy . depends on the current requirements... 3.7 volts should be fine but the 75 mAh capacity might only last you an hour !! again depending on current draws. there are deep sleep modes for the Arduino and the esp so meticulous programming will give you a better life. ( upto a few years depending on the number of times you want it to wake up)
can you modify by adding antenna to make it long range
Is there a follow-up video to this one? I just bought a 100 pack of cards and several readers I want to make ap roject out of. I want to try and use it to play a trading card game with another player over the internet using real cards and a placemat with readers embedded in it
i read elsewhere that level shifter are needed to use this board with arduino, because not all of the mifare are 5v tolerant, and the board itself is 3.3v... any info about this? thanks
squalazzo it's 3.3v board so no level shifter needed
Very informative video. Would you happen to know if this device would read chips used for pet identification? One such chip is the ALLFLEX ISO FDX-B transponder. Thank you, Eric
i bought 2 modules, and both my tags work, but none of the cards! anyody know why? are they blank and has to be written to?
I'm using Arduino Pro Micro to connect to Mifare RFID reader. I have connected everything but not sure what's the Pin number of the RST to write in code. Here's the definition...
* RST/Reset RST 9 5 D9 RESET/ICSP-5 RST
In RFID_DumpInfo program, and when I use Arduino Uno I used #define RST_PIN 9 BUT what should I define it when using Pro Micro? What's the RST pin number in Pro Micro?
hi, can you advice me which is the best read and write machine to be use for Elevator & Car parking cards? Thanks
Hi, I was wondering if I can make up my own pin numbers... I am using a raspberry pi and those pins have already taken
ou could use the cards, or the fobs as a computer access key, instead of a traditional password. Just a thought.
Is is possible to boost the distance of the antenna on the rc522 chip
what is the putty you use on the back of the components to hold them down and in place while your working on them?\
thanks
maybe you can use it to set/load some data to a device to change it's behaviour?
Can you please tell me which are the cables you use to connect the Reader to the arduino pro mini?
This is awesome, where would one start learning on how to understand all of this?
I would like to know the same
Hi freind,This is grace from Greenrfid company,we are a card manufacturer in Shenzhen China.we can provide all kind of card to you. My Email is grace@greenrfid.com or leave your contact information.let's talk details.
Funny that they published the paper of de encryption (hack) study done in Holland.
When everything transportation went digital in Holland, it automatically became a target for hackers.
It was published in a computer magazine how it was done as well.
Can you make something that outputs ONLY the UID? for a simple insecure card lock
You seem to know quite a bit about RFID and such. At work we have an door with a key pad. I'm pretty sure it reads RFID as well. I think my question is about the frequency of these things. They are not al on the same RF freq. Will these readers be able to get the frequency from the door and be able to write the access pin onto the card? do they make separate cards for each frequency? I don't know enough to even formulate the proper question. I would probably need to have the frequency the door keypads receives before I would go out and purchase a reader/writer, cards/chips?
Those RFID tags/readers as in this video all work at the same frequency(13.56MHz). Older RFID keypads(like 10 years ago) might use 125khz systems.
hi, great video, but i am looking for a solution to my UHF range RFID reader....I want to connect it with the controller..pls help
Is it possible to change the UID using Arduino for such tags?
Or where can i get tags with rewritable uid?
