The aluminum tray effectively protects (RFID-safe) your cards from being read by external scanners. The contents of our wallets have recently changed and we use more and more cards with computer chips and built-in antennas. It increases ease of use, but it also involves risks. With this card holder, you don't have to worry about that. The card protector is the heart of our card holder. By sliding a small lever to the side, your cards are fed out of the card cover in an overlapping sequence. You can do this without opening other parts of your wallet and you can quickly find the card you want to use. You only take out one card when you want to pay and as long as the others remain in the aluminum shell, unauthorized equipment cannot read the cards. The risk is further minimized in this way.
