Credit cards that contain small RFID chips can be scanned by thieves to steal your data. Help protect your plastic with our RFID credit card sleeves. It's a cheap way to ward off credit card data theft. Of course, to be 100 percent staff from thieves scanning RFID data or stealing your cards outright, leave them locked up at home. But when you must bring your cards with you, RFID card sleeves add extra security. It's even easier for thieves to simply pick up and run with a credit card that has fallen out of your wallet. That's why our Big Skinny uber thin wallets have a non-slip coating inside each billfold wallet to help secure your plastic cards and cash. Shop our wallets with fully zippered perimeters for even more protection. Pickpockets won't find anything in your back pocket when you're carrying one of our compact extra-skinny wallets in your front pocket.
