Finding FRID Protection Sheets

[AzShooter]

Anyone know where the FRID protection sheets for wallets can be found?

I use to get them from Tandy but can't find them on their websites anymore.

This works according to what I’ve heard…

Thanks for the information.  I ordered one.

I use plumbers aluminium heat proof tape. Comes in a big roll 2'' wide. Costs about £5 to £8 per roll. I've multi-tested it and it works perfectly

Interesting!

I know you're probably not asking - but RFID blocking material is a scam. Its marketing that plays into people's mind about theft.

RFID is supposed to block a 'sniffing' crime. AKA - someone can 'sniff' using a RFID reader and obtain sensitive information about said card. However there isn't enough information that someone can gain by 'sniffing' your cards. So much so, they can't pinpoint a single crime to RFID sniffers.

"So, experts point out, even if someone were to successfully use a surreptitious reader, which would need to be within inches to sniff your payment information out of thin air, they would need to crack the bank’s complex algorithm to generate a new one-time code to complete another contactless payment. Contactless payment options like Apple Pay and Android Pay use near-field communication (NFC), a version of RFID, and since they require further authentication from the user, are even more secure, say analysts."

There are many reasons to use RFID blocking linings. One of the most common in my neck of the woods is avoiding "card clash" where you have multiple NFC-enabled cards in one wallet. Put your most commonly used ne (debit card for instance) in an unshielded outer pocket and your multiple others inside the protective cocoon of a Faraday cage and things work much smoother.

Now that - is a pretty interesting idea. So yeah I could see that. To be able to just tap your wallet against the terminal. That is truly the first good argument I've heard for RFID blocking.

Not really a scam using blocking material

Christmas before last N.I. police stopped some thieves using a store type card reader to get payments into their 'account'

The thieves were doing 'sales' of about £25 a time - the card limit on contactless was £30 - and were simply going by womens' handbags in very busy & crowded shops. They passed the card reader over near the handbag and the reader took the money from the card. Police would not give full details, for obvious reasons but advised women to use a RFID card holder

Here is the thing, a scam like that would require people to have a merchant account with valid information. It has to go through card processing and only then to a bank account. The person would have to be close enough to someone's pockets/bag to even activate it. Like very close. So close you have to about an inch on the reader.

It is no different of a scam than someone taking your debit card at a restaurant, writing down the numbers and entering it on the computer later on.

Fortunately, these scams don't go well because you as the customer are protected as it is fraud and you can merely chargeback, but secondly if a merchant sees numerous chargebacks, it freezes the account and refunds all the transactions. 

RFID is a scam because the risks and likelihood of it happening is nearly 0. Even if someone does manage to stick their terminal into your bag, maneuver the card within an inch and process a payment. You're protected through your banking and government regulations. 

EDIT: Forgot to mention - the space needs to be clear, so if you have more than 1 card in that 1 inch bubble 'dead space' it doesn't read. So general objects obstruct it. Clothing, bags, wallet material.

Bankrate says

 

RFID credit cards allow you to pay with a tap, rather than inserting or swiping your card. Special RFID-blocking wallets and sleeves, despite their popularity, generally aren’t necessary for security because the technology requires an obstruction-free environment. In other words, most materials—such as a regular wallet, a purse, or a pocket—will prevent the RFID technology from working, making it tough for a scammer to tap your card without your knowledge.
