Theres no need to buy such fancy advertised NFC blocking card. I have made a lot of them by myself using aluminium foil you use for making meal, grilling. you cut a few layers to the correct size and foil it with laminator. Perfect.

Flipper is a "base model." Near-field ability can be greatly extended by adding a supplemental long-range directional antenna to flipper. Near-field is generally "within a few inches" but, in theory, with the right equipment, you can pick up NFC data from further away.
About 10 years ago I saw an item on TV in France. They walked through a shopping mall with a similar device and succeeded in taking one Euro from the credit or debit cards of about 20 people in the mall. The TV program immediately refunded the money but that was scary. They could have taken up to the tap transaction limit which for most cards is about 200 euro. So like 4,000 Euro in a 10 minute walk through a mall. I have used those sleeve things ever since.
I'm immune to the flipper. I only use cash. No credit, debit, or bank card. If I didn't live the way I do and had one, I'd be very concerned about right now. Sometimes the best defense against high tech is to be low tech.
You're right about it being a pain slipping the card back into one of those little Faraday holders. What I do is to keep two in my wallet and easily slide the card between them.
to prevent this, there are infoless cards without numbers. If you want to make online payments, you have to use a virtual card with a dynamic CVV. At least in Mexico, there are some banks that operate this way.
Just a clarification: The nfc cards that were "copied" aren't actually vulnerable to attacks of this sort, nowadays EMV bank cards have cryptographic algorithms that run inside their chips to verify transactions using a sort of public-private key transaction with the bank through POS terminal. What this attack is doing is essentially stealing the ID that the card uses (aka card number) to identify itself with the bank so it can send back a challenge code. This might be helpful to cybercriminals as some credit cards send all of their information through the nfc signal (including cvv and exp date which might be used to make online transactions), but should not work for performing transactions at contactless terminals with the flipper.
Hi ya Liron! Ya, seen that zipper being used in my local supermarket but security was happy enough to escort the young lad outside The M5 stick, stack and Stamp have similar behaviors. Good content us always 👍
A word of warning(?) This probably applies to your phone as well. I use my phone (in the UK) with NFC when shopping. However, I ALWAYS turn it off after the transaction.
I tried it with various phones, but that didn't work. It could read some NFC info, but nothing "useable". I am continuing to test though. But yes, can't hurt to disable it when you are not using it.
Roger I 100% agree with you about switching off the NFC after doing a transaction. I also do the same, in fact I prefer using my phone instead of using the contactless card for that very same reason that Liron has done in this video. Thank you for the advice Liron Segev, your a legend sir.
I don’t disable it. Actually, I use nfc payments with only face recognition tech in iPhone 11th max. If face recognition is not used, it does not pay at all. Did you try that?
Try inserting some folded kitchen aluminium foil sheets between the purse or/ wallet pockets, it should prevent the Card Scanner from extracting one's credit card info. Especially useful when travelling overseas.
I looked on Amazon at the card for your wallet. I see this comment there in the description and don't understand what or why you would need to do this. When you go to pay, place this card on top (or bottom) of your payment card and place on the contactless reader.
one of the workarounds that my bank has for this, is if above a certain amount of money is spent on an online purchase, the bank app on my phone will send an alert, asking me to confirm it by inserting my phone PIN not the card CVV, so tough nuts to the scammers
Not sure how this is new info, been using RFID sleeves for years now, even most decent wallets have RFID protection. Also, some Passports can be read, and your ID cloned, So if you are an international traveller, definitely get protected
skimmers that can be tucked in sleeves were used for years to clone magnetic strips. to get an portable RDIF/ NFC scanner, you needed a laptop/ raspberry pi. I haven't seen something this "user friendly" without any learning curve in a long time...
@@LironSegev I honestly thought it was common knowledge. love the channel Liron, especially going through the older vids for Windows tips & tricks. Just to add, might also be worth you looking at Faraday bags for anyone super cautious about their phones, whilst in unfamiliar places.
I have an aluminum wallet. My debit card is in the back slot, between my Walgreen's discount card and my WSS (shoe store) preferred customer card. I keep the wallet in my front pocket, with the back of the wallet against my leg.
Another great video. You mentioned that the Flipper can give the thief your credit card information and the expiry date, and then you are showing us that when adding a new credit card, with Amazon (for example), they only asks you for your Credit Card number, the Name on the card, and the Expiry Date. So does Flipper also capture a person's Full Name as well?
Why do the issuers of credit cards allow vendors to not require the CVV code? Only someone who does not own the card would not be able to provide the number.
@@TheGamerRedline No, because I always memorize the code and scratch it out from the card. I had charges come up on Spotify which I had never subscribed to. I suspect it was done by a waitress I handed my card to. So Spotify did not require the code.
The FZ's OS has hard wired limits whenever it detects it has read a bank card of any kind it will NOT let the user Emulate the card, It can still read and replay normal NFC anf RFIDs though.
He says 6cm. Google says: "UHF RFID readers: The biggest advantage of UHF RFID card readers is their long reading and writing distance, which is generally 3-5m and can reach up to 15m. Passive low-frequency (LF) and high-frequency (HF) tags can be read from a distance of up to 3 feet (0.9 meter)"
As far as I know that card you put in your wallet to protect the other cards does so by taking all the power of the nfc device. You can also use one of the paper based travel cards (like oyster cards in London). Based off that though, I wondered if just having multiple cards all together would stop the flipper from being able to read any single card because all cards will try to use power at once.
You people are hilarious. You can use aluminum foil. All you need to do is create a layer of materiel the signal can’t go through. Like having your phone in a tunnel. Basically a Ferreday cage. It’s like boomers don’t know what rfid blocking wallets are.
Good video, Liron! Nicely informative and concise! Been working with chip cards since 1991. The ways that they can be hacked (even before RFID) was scary then. When I got my first card with RFID, I got one of the RFID shielding sleeved because I already knew how vulnerable the cards were. I mean, come on, folks! If a terminal in a store can read it, how hard do you think it is to get something like Flipper and read someone's card info? Thanks again!
I always carry my wallet in my front pocket. If anyone would try to use the flipper on me, they would have to get in front of me and if they would try to swipe the flipper they'd have to get close to my front (privates) and that would be very suspicious and I'd push them away or give them a knuckle sandwich! Shure it's not 100 percent fool proof, but it's been pretty safe for me so far.
fun story: I was pickpocketed in Rome and my wallet was in my front pocket. The lady who did it was such a pro and got it just as I put my leg up to get onto the train...I felt nothing. She was a pro
The Italian pickpockets are pros. Decades ago my mom had her arm sitting along the entire top zipper of her purse. The bus ride was short and not crowded. They somehow, got under her entire forearm, unzipped it enough to find her wallet and remove it. She never moved her arm or felt anything. And her zipper appeared to remain closed
When I go out, I take my debit card and usually one credit card. I put them in my shirt pocket. This makes it inconvenient for anyone to steal the information.
You can line your wallet with tin foil, also you can face your cards with the top of strips back to back facing each other and it works, you don't have to buy RFID card.
I swear, you provide the most useful, concise, comprehensible tech videos ever... thank you. I was wondering if those metallic cases which hold multiple cards and are alleged to block readers, actually work? I was given one as a gift ages ago and will start to use it if it is effective.
A card I used to have (sadly they are no more - FIDOR), you could block all countries but the one you were visiting (or buying from if on the internet). My current main credit card can be disabled by my phone app, or even having the card blocked but simultaneously having the same card active in my Google Wallet.
So, what happens if you have two, three, four NFC-enabled credit cards in the same wallet? Can the flipper focus in on just one, or do the multiple signals confuse it? Is that, perhaps, how the card for your wallet works? Does it just add another NFC signal to confuse the flipper?
Using NFC on a credit/debit card requires a two way handshake that is cryptographic, which the flipper cannot do. It can read the card number for most cards but in most cases the info is useless barring maybe using the number to pay an electric bill over the phone, but in most cases that requires a CVV number which the flipper cannot retrieve.
@@LironSegev Same, Ive got the 100milliwatt flux capacitor with a high gain antenna on it, as well as wifi and nrf boards. I spend most of my time though, writing python code to parse raw files to find packet timing, and convert the message to binary/hex and then convert that over to c16 files for use on the hackrf-portapack. Love my flipper. Hate that people dont undrstand it though.
So the flipper can read cc info but then you have to have a way to make a duplicate card, right? You cannot go online and buy stuff because you won''t have the zip code
I try not to let people get that close to me anyway, but if they do, I have those RFID blocker cards inside my RFID wallet, so I'm not sure what else I could do.
The flipper does NOT copy the CCV code. Without that or at least the zip code of the card holder, the card number and it’s expiration is useless. This feature is dumb.
Because it would cost$.00000005 per customer and why would they waste their money on a protection they few customers would bother using. And they aren't going to educate their customers on the fact that their cards are not that secure.
Indeed, it is true that this device can perform all the functions described in the video, but there are a few limitations regarding the NFC scan and what it can actually detect. I examined all of its features a few months ago. 👌🏼
Liron... Google (Chromium), Brave (Chromium), and very possibly Firefox (Mozilla) are discontinuing updates for their web browsers for Windows 7 and 8.1. Besides updating their OS, what can Windows 7 and 8.1. users do as far as having the most secure, privacy centered, internet compatible web browser and which one would it be with Brave (for example) off of the table?

but if you use that card and if someone complaint that card was using, they will find where was shipped if you purchased something, so doesnt make a sense,
I have a flipper, and yes, it can scan a card #, but not the security code, zip code, or holder name. A phone is more useful than a flipper in this case.
@@shenlun does your card physically have the wifi sign on it? If it does you have nfc if it doesn’t you don’t. As far as I know when you receive your card you have to activate it to even use it. If you haven’t activated your card why would you be carrying it?
@@TopGAli Yes my card has the NFC/wifi logo, yes my card is active for general use, but in Australia we have the option NOT to activate the touch and go feature. My question here is that even though I haven't activated it will flipper, for example, still be able to grab my details, and a demonstration would be appreciated.
if I have an RFID blocking wallet containing my credit or any other cards , will a flipper still work and allow the unscruplous person to illegally access my card info ??
You don't have to get expensive tech to protect against expensive tech . I simply put a sheet of heavy duty ALUMINIUM FOIL on the lenght of the dollar bill compartment - this creates a FARADAY CAGE when the wallet is folded.
I want to know if the brand of RFID blocking card makes any difference, or are they all about the same in terms of effectiveness? In the UK some of those blocking cards can cost £30 for a pair. Or there are cheap ones at around £5. If anyone knows, please help.
Great video, thank you. Do you know if the Flipper can read data when you have more than one card in the Flipper´s range? I mean, one card "sticked" to another?
my card is in a metal case received from the bank, but I still don't pay anything contactless with my pin code, don't have it for those digital things, there's a lot more behind it and we have to be careful every second of the day.
Thank Liron for this INFORMATIVE video. One question, please. I was told wrapping my card in an aluminum foil envelope also protects it from reading devices like Flipper. Is that true? If possible, could you please make a video about it? That would benefit all of your subscribers. Thanks again.
Thanks for the nightmare fuel... So basically everyone needs to buy a protector when they leave home with a card now. This needs to be fixed asap if possible without the need for protectors.
Modern bank cards have encrypted data which makes these devices useless. At least European, i.e. Dutch banks etc. Those blockers are quite redundant these days.
@@LironSegev yes. If you try this on a bankcard from a Dutch bank it's unlikely to to work. The rfid vulnerability has been dealt with a long time ago. All data is encrypted which you cannot decrypt on the fly with a small device. May i ask what card you tested this on?

You can line your wallet with tin foil, also you can face your cards with the top of strips back to back facing each other and it works, you don't have to buy RFID card.
I swear, you provide the most useful, concise, comprehensible tech videos ever... thank you.
I was wondering if those metallic cases which hold multiple cards and are alleged to block readers, actually work?
I was given one as a gift ages ago and will start to use it if it is effective.
I havent tested it myself, but it sounds like it can. I tried it aluminum foil and that blocked it
@@LironSegev
How about Apple Pay?
Another Great Video. Thank you, Liron. 😎
appreciate it!
The range is determined by the reader. Some stores have reader that “tap” your card from 5’ away.
The dude does it yet again! Short, to the point and VERY useful.
Keeping it as on point as I can...we all got stuff to do and no one wants to know that I had coffee. Just show me the info haha
@@LironSegev there are a lot of videos on the flipper and yours is, by far, the best one I've seen about the nfc feature. Thank you.
Appreciate you 🔥
Another thing that will help is to keep your cards locked until right before you use them.
A card I used to have (sadly they are no more - FIDOR), you could block all countries but the one you were visiting (or buying from if on the internet).
My current main credit card can be disabled by my phone app, or even having the card blocked but simultaneously having the same card active in my Google Wallet.
I love thes Jaapes from South Africa. Not just their accents but thir delivery. Excellent stuff. So wwell explained.
So, what happens if you have two, three, four NFC-enabled credit cards in the same wallet? Can the flipper focus in on just one, or do the multiple signals confuse it? Is that, perhaps, how the card for your wallet works? Does it just add another NFC signal to confuse the flipper?
I've also wondered that. I hope someone answers.
Yes absolutly you can filter what you arr looking for! ;)
@@mikewgagne do you mean it reads all cards stacked together at once?
Using NFC on a credit/debit card requires a two way handshake that is cryptographic, which the flipper cannot do. It can read the card number for most cards but in most cases the info is useless barring maybe using the number to pay an electric bill over the phone, but in most cases that requires a CVV number which the flipper cannot retrieve.
Eh...did you watch the video?
Yessir, just giving a little TLDR; for the folks that wont watch the whole thing. Great video and very informative. :)
Haha those people aren't the right people anyways. I love my flipper and with custom mods it's a powerhouse!
@@LironSegev Same, Ive got the 100milliwatt flux capacitor with a high gain antenna on it, as well as wifi and nrf boards. I spend most of my time though, writing python code to parse raw files to find packet timing, and convert the message to binary/hex and then convert that over to c16 files for use on the hackrf-portapack. Love my flipper. Hate that people dont undrstand it though.
So the flipper can read cc info but then you have to have a way to make a duplicate card, right? You cannot go online and buy stuff because you won''t have the zip code
I try not to let people get that close to me anyway, but if they do, I have those RFID blocker cards inside my RFID wallet, so I'm not sure what else I could do.
I just added the sleeves to my Amazon cart. Thank you for the tip.
Cheap solution to really help. Sad that we need it, but here we are...
The flipper does NOT copy the CCV code. Without that or at least the zip code of the card holder, the card number and it’s expiration is useless. This feature is dumb.
Why don't credit card companies provide those protective sleeves to their customers?
They are thieves, too...when you consider their interest rates!
Because it would cost$.00000005 per customer and why would they waste their money on a protection they few customers would bother using. And they aren't going to educate their customers on the fact that their cards are not that secure.
Indeed, it is true that this device can perform all the functions described in the video, but there are a few limitations regarding the NFC scan and what it can actually detect. I examined all of its features a few months ago. 👌🏼
it doesnt read the encrypted security code right
it doesnt
@@4foreigns
Liron... Google (Chromium), Brave (Chromium), and very possibly Firefox (Mozilla) are discontinuing updates for their web browsers for Windows 7 and 8.1. Besides updating their OS, what can Windows 7 and 8.1. users do as far as having the most secure, privacy centered, internet compatible web browser and which one would it be with Brave (for example) off of the table?
You'd have to be nuts to hold a credit card .... I'm thinking the same now with my mobile phone also
You should do a video on how Secure Customer Authentication basically makes the collection of this data irrelevant.
…..
I'm a Police officer and I'm tired of taking these reports where people are scammed anywhere from 100 to seriously $50,000. It's quite unfortunate, VAULT GUARD EXPERT seriously thank you for flagging down these swindlers and doing refund. You make me want to spend my next 10 years learning how to do this.
The information is so useful because people are so relaxing when it comes to their ccards.
100% - too relaxed!
Yes you can use it to pay for things but only on certain devices, Walmart old systems isn't one
It has to be very near almost over the credit card to steal the information. There are other devices that can steal almost at 20cm the info
but if you use that card and if someone complaint that card was using, they will find where was shipped if you purchased something, so doesnt make a sense,
What about aluminum foil? Seems like that might block someone trying to read your card
I’m guessing the flipper inventor also produces the card protectors 😅
there are RFID blocking wallets which you can just get... so as long you keep your card inside the wallet you are safe...
I have a flipper, and yes, it can scan a card #, but not the security code, zip code, or holder name. A phone is more useful than a flipper in this case.
Yup
But can still use the number and expirty date without the cvv code. Like I showed
What happens if your card is NOT registered for tap and go, like mine is. A quick follow-up video showing the result would appreciated. Thanks.
Common sense says nothing will happen then. Your card is not NFC compatible.
@@TopGAli But my card is compatible with nfc I just haven't enabled the function via my bank
@@shenlun does your card physically have the wifi sign on it? If it does you have nfc if it doesn’t you don’t. As far as I know when you receive your card you have to activate it to even use it. If you haven’t activated your card why would you be carrying it?
@@TopGAli Yes my card has the NFC/wifi logo, yes my card is active for general use, but in Australia we have the option NOT to activate the touch and go feature. My question here is that even though I haven't activated it will flipper, for example, still be able to grab my details, and a demonstration would be appreciated.
@@shenlun ok yeah that’s different than here in the US. So, I don’t know.
Piece of metal sheet or even aluminium foil also block NFC reading... I have stick Au foil inside my wallet...
if I have an RFID blocking wallet containing my credit or any other cards , will a flipper still work and allow the unscruplous person to illegally access my card info ??
finally someone that tried to emulate de "stolen" information to buy something. nice video
Glad you liked it!
Thank you very much 😊
That's an Actual scammer face at 4:22! 😁😂🤣😭
Great content; Let's Go!!!💪🏾
no comment 🤪
Thank you for this excellent video. Great work and to the point explanation with clear examples. Subscribed.
Awesome, thank you!
No one keeps one card in their wallet. Which means you are scanning all of their cards?
You don't have to get expensive tech to protect against expensive tech . I simply put a sheet of heavy duty ALUMINIUM FOIL on the lenght of the dollar bill compartment - this creates a FARADAY CAGE when the wallet is folded.
I want to know if the brand of RFID blocking card makes any difference, or are they all about the same in terms of effectiveness? In the UK some of those blocking cards can cost £30 for a pair. Or there are cheap ones at around £5. If anyone knows, please help.
I have heard that they can read your card from several feet away, not just a couple of inches.
No they can't. The maximum distance of NFC is only 4 inches. Doesn't matter how powerful of a device you have.
I have begun using a vest wallet so that my rear is no longer financially hackable.
Great video, thank you. Do you know if the Flipper can read data when you have more than one card in the Flipper´s range? I mean, one card "sticked" to another?
It cannot, the codes generated by multiple cards confuse the reader showing errors when trying to read the cards.
All you can get is the number and year of expiration. No CVV code, etc.
Almost like what I said 🤪
Thank you!
Please do another video about the efficacy of these blocking wallets. Thanks!
They ask for billing addresses...they need to match.
This is why I always buy Pacsafe bags and wallets because they have the rfid blocking features.
Aside from Near Field Communicaration theres's RFID Radio frequency Identification too
I HAVE HAD THOSE SLEEVES FOR YEARS. USED IT ON MY PASSPORT & IT BLOCKED TSA. I ALSO HAVE A RFID WALLET
great
my card is in a metal case received from the bank, but I still don't pay anything contactless with my pin code, don't have it for those digital things, there's a lot more behind it and we have to be careful every second of the day.
Thank Liron for this INFORMATIVE video. One question, please. I was told wrapping my card in an aluminum foil envelope also protects it from reading devices like Flipper. Is that true? If possible, could you please make a video about it? That would benefit all of your subscribers. Thanks again.
Thanks for the nightmare fuel... So basically everyone needs to buy a protector when they leave home with a card now. This needs to be fixed asap if possible without the need for protectors.
Do the NFC/RFID blocking cards also disrupt the Apple Find My functionality of AirTags and tracking cards (Nomad, Chipolo, etc)?
Why don't manufacturers just cancel the tap and pay function on the card and save us a lot of headache.
Awesome as always!
thanks for being here!
Modern bank cards have encrypted data which makes these devices useless. At least European, i.e. Dutch banks etc. Those blockers are quite redundant these days.
Did you watch the rest of the video? 👀
@@LironSegev yes. If you try this on a bankcard from a Dutch bank it's unlikely to to work. The rfid vulnerability has been dealt with a long time ago. All data is encrypted which you cannot decrypt on the fly with a small device.
May i ask what card you tested this on?
38 cards from 17 banks in the US. 32 of them worked. You can't get the cvv number from any of them
@@LironSegev hmm, looks like usa is approx 10 years behind on the cards tech. Curious to see what would happen here. Will ask around.
No comment towards you btw:) i was just very surprised
@@LironSegev Also, those blockers work well when its needed. I have a wallet that has it built in. I don't need it so its basically a bonus. But its more practical than those sleeves:)
