Aluminum case provides effective RFID protection, safeguarding 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 embedded computer chips and antennas. While this enhances convenience, it also introduces security risks. With this cardholder, you can eliminate such concerns. The protective shield is the core feature of our cardholder. By sliding a small lever to the side, your cards are smoothly ejected in an overlapping sequence. This allows quick access to the card you need without opening other parts of your wallet. You only expose one card at a time when making a payment, while the rest remain securely shielded inside the aluminum casing, preventing unauthorized devices from reading them. This further minimizes risk. Material: Aluminum Holds up to 5 cards Dimensions: 97 x 65 x 13 mm Weight: 62 grams
