How Can I Protect My RFID Credit Card?
What is the best option for blocking people from stealing information via the card's chip?
There are a number of products on the market, such as Skim Block, as well as RF block wallets and sleeves. Consumer Reports, however, says that tests carried out by security firm Recursion found quite a bit of variability in the products' ability to block the RF signals from readers. Therefore, I personally would recommend saving your money and simply wrapping your credit cards in a few sheets of tin foil. By the way, you should be aware that RFID credit cards are safer than magstripe cards, which can be easily cloned.
