KeepSafe RFID Passport Wallet:: review In a crowded store, market, elevator or subway, identity thieves with the latest equipment can scan the electronic information from your credit cards or passport while just walking past you. The black wallet is also a stealth way to hide your passport from old-school, five-finger theft as well, blending into the fabric background of a purse or suitcase. The leather is smooth, soft and grippy, and seems sturdy enough to last for many trips.
