RFID Reader Protection
RF Blocking Credit and Debit Card Sleeves
Credit Card Sleeves may sound like a paranoid way of protecting your identity, but you need to consider what you're up against. If you have a credit or debit card that just has to touch a reader, then you have an RFID tag embedded in your credit card. In a manner of speaking, an RFID tag is a tiny radio that sends your information when it gets within the proximity of a reader. A person walking down the street with a smart device may be able to collect signals from hundreds of such credit cards in a matter of minutes. Therefore, a credit card sleeve serves as "tinfoil hat" technology to keep the signal from getting out, except when you are ready to make a purchase.
