I see these wallets that say they block RFID readers.. what do they use to do that? is it a liner?

This is pretty cool. It looks super thin and pretty cheap too. If I was making a bunch of wallets to sell I put this in every one of them as an additional selling point. It's so cheap you wouldn't have to pass much of an additional cost on to your customers. If I make another wallet for myself or a family member I plan on putting this in it. Like why not. I don't know how this has been out but it's the first time I've seen it. RMLS - 0.1mm RFID Blocking Fabric Mesh

I would imagine that a holster that incorporated RFID fabric would only have the fabric on one side between the phone and the body. The phone would still be able to receive signals from the uncovered side. However I doubt how effective that would be. The radio waves from the cell phone would still spread out around the holster, so the protection would probably be minimal. /dwight

I assume that the maker/owner of such a holster must not be interested in receiving calls on their cell phone. Material that blocks RFID will block other electromagnetic radiation (signals) making the cell phone useless wearing it this way! Concerned about radiation from your phone, leave it on your desk/dresser/table at home!

I'm not sure how well it would work for cell signals, but Rocky Mountain Leather Supply has some RFID Blocking fabric that might be worth looking at for this: https://www.rmleathersupply.com/products/rfid-blocking-thin-fabric-0-1-mm-self-adhesive-back?_pos=1&_psq=RFID&_ss=e&_v=1.0 /dwight

I think; The general public doesn't know all this. The newspapers reported, correctly or not, of peoples card details being stolen, the public read this and believed it. The fitting of RFID blocking material is like a comfort blanket to the public There was a similar 'scare' when we used the paper and roller system. Where the card was put in a hand operated machine, a paper receipt put on top. A roller was run over them and the card details were impressed into them, then we signed the receipt. The 'scare' was the shop was making two copies and the second was put thru with the first for payment; you were paying twice.

Here is some more backup information including digital wallets from another company: Tapping to make a purchase isn’t all about making your life simpler, it also creates a more secure way to shop. By using a combination of chip technology, Near Field Communication (NFC), and Radio Frequency Identification (RFID), contactless cards are safer than your traditional swipe or insertion of a credit or debit card. This is because each transaction uses a one-time, unique digital code to facilitate secure communication between your card and the card reader. This dynamic authentication process significantly reduces the risk of card fraud and unauthorized access to your financial information. By embracing contactless payments, you can enjoy peace of mind knowing that your transactions are protected by advanced security measures. Because there is limited physical contact with payment terminals and cashiers, there is a reduced risk of skimming devices or malicious software stealing your card information. By minimizing physical interaction, tap to pay helps protect against card cloning, counterfeit fraud, and other forms of tampering. In the event that your mobile device or digital wallet is lost or stolen, many digital wallets offer additional security such as biometric authentication (fingerprint or facial recognition) or a unique PIN to ensure that only authorized users can access your payment information.

This past year, many CC companies have implemented new processes for RFID or contactless CCs. Many cards have been replaced a year or more before their expiry date. AMX bumped us into new cards 2 years before the expiry date. They no longer transmit the CC account number. Instead a transaction number is transmitted. It is only good for that one transaction. I looked for the info I had a few months ago but can't find it now. They are pretty quiet about its details. One CC company describes their process as: Chip technology. Your Credit Card’s chip is essentially an updated, more secure alternative to the magnetic strip on the back of the card. For each transaction, your chip creates a one-time-use encrypted code that’s used to instantly verify your account information. Because a new code is created every time you dip your card, it makes it impossible for a fraudster to make a counterfeit of your card. The stories about someone lifting your CC account number while you are walking down the street will disappear with this change. It has been implemented in Europe before USA and Canada finally started to adopt it. So has had a good run of testing. Hope it continues to be safer.

I use to carry my credit cards in a RFID protected wallet but recently read where the newer cards can't be read by someone passing near by, a reader would need to be within inches. true? i don't know but the person that wrote it works for a major credit card company.

Working on a new Credit card holder for the Secrid RFID card holder. Basically a wrap that allows you to carry more card size items. Gini loves Sunflowers so we used this design from Jim Linnell and sized it to fit. She has one now I made a couple years ago and it shows how far my skills have come. Time for a new one.

Has anyone used Faraday fabric for RFID blocking? I was wondering how it worked.

Tl;DR: RFID blocking is not at all necessary for security. It's just a marketing feature for a wallet maker. I do leatherwork as a hobby but my day job is in the credit card department of a bank. Theft via portable RFID scanners had been becoming a major issue at one point, you could walk through a crowd of people with a scanner in a briefcase and from several feet away capture people's credit card information, which could then be used to make transactions. My bank stopped offering paywave as a feature on their cards. A few years later they reintroduced that feature on newer cards. I contacted our fraud department directly and asked why they would do this, considering the security risks we saw materialize last time. They got back to me and explained some of the features in the reintroduced RFID system. While the old ones could be read at a greater distance, current ones must be within 3 inches or less from the machine. The old ones gave out the card number itself, which is what thieves can use; the new ones work like the EMV chip, that does not give out the 16 digit card number, but instead generates a one time use code that only works for that one transaction. If anyone were to scan your card now, all they'd get is a one time use code that's already been used and they can't even use it for a single transaction. This is also what merchants get when you insert your card to use the EMV chip, the merchant never gets your actual card number (which is reusable), they get a code that works only once for that transaction. This way if the merchant's system is hacked, the hackers don't get CC#s they can use, they just get used up codes they can do nothing with. You don't need RFID blocking for security at all. It might be worth advertising it if your customers think it's a good idea, even though it won't improve their security.

Had a fun wallet case to do for a Secrid RFID wallet. Only one more sheath to do for Christmas.

Brands, cuts and bruises all give leather a certain character which some people admire., while others abhor. To each his own, utilize the scars to good effect and you will come closer to pleasing most of them. Chrisash, ear tags have been used in N. America for decades. And branding has not been totally abolished in Europe. Tatooing inside the lip is also used here, as well as RFID chips, especially on high value stock. Ear notching is still used on some stock, as well.

Its simple to make your card wallet RFID (Radio Frequency IDentity) protected. Glue into the pockets, or use double sided sticky tape, pieces of kitchen aluminium foil. A piece on the inside of each of the outer covers will do. For best practice the pieces of aluminium foil should be at least the same size as the cards, about 8cm by 5.5cm

Man that sucks. I hate the ' tap & go' shite. Heres an example why I hate it: I went to a bottle shop ( liquor store) got what I wanted, went to pay with savings card, just about to put my card into the machine, and ' beep beep ', " approved" ....WTF ??? The damn machine picked up the 'tap and go' on my credit card that was in my wallet ....in my left hand, a good distance from the machine. Its happened to me a few times now. So, I went to my bank and got the tap and go component deactivated . They are too dangerous an what happened to you is the reason why . But yes, I would warn others and notify your bank as it could be happening to other people without their knowledge , and , they may be able to do a trace back to the offender. There are RFID materials or devices that prevent it happening, but you shouldn't really have to, or alternatively , deactivate the tap & go . Also, some banks ( here in Oz anyway) charge a little extra for that " convenience " . HS

Nowadays there’s a better chance you will lose your whole wallet to a pickpocket than encounter someone exploiting RFID.

As fredk recommends, aluminum foil works great too! Most gimick fabics dont work from my experience(ex IT geek), lots of theives line thier bags with alfoil to evade scanner... Im keen to make a rfid card holder too but looking for alternatives to aluminum, would that work long term? Also it has to seal well or be wrapped to work well?

For my own personal credit card, I went to the bank and got the ' pay wave' component deactivated . The EFTPOS machines kept picking up my credit card while it was still in my wallet and no-where near the machine, it was in my left hand and I do transactions with my right, either with cash or a savings card, go figure. I didn't realise how sensitive those machines are. But I really should think about using RFID shielding when I make wallets. HS

Did you try a search here? Lots of threads. https://leatherworker.net/forum/search/?q=rfid&quick=1

Yes, I decided to create an RFID blocking card wallet. Here is the result.

I don't know. I thought maybe that was a RFID shield. Just a wild guess. Or maybe a poly strip?
