RFID-blocking aluminum protection effectively shields your cards from unauthorized scanning by external devices. The contents of our wallets have changed in recent years, with more and more cards now featuring computer chips and built-in antennas. While this improves convenience, it also introduces risks. With this card holder, you can eliminate those concerns. The protective shield is the core of our card holder. By sliding a small lever to the side, your cards are pushed out in an overlapping sequence. This allows quick access to the card you need without opening the rest of your wallet. You only expose one card at a time when making a payment, while the others remain securely inside the aluminum casing, preventing unauthorized devices from reading them. This further minimizes risk.
