Business Card Holder Aluminum Alloy Metal Card Holder RFID Wallet Credit Card Case Automatic Pop-Up Card Case Business Card Holder, Black, 10cm*6.3cm*1cmThe aluminum tray effectively protects your cards from external scanners. The content of our wallets has recently changed and we are using more and more cards with computer chips and built-in antennas. It increases ease of use, but also brings risks. With this cardholder, you don't have to worry. Card protection is at the heart of our cardholders. By pushing a small lever aside, your cards are removed from the card cover in overlapping order. You can even do this without opening the rest of your wallet, and you'll quickly find the card you want to use. You just pick up a card when you pay, and as long as someone else stays in the aluminum case, the card cannot be read by unauthorized devices. The risk is further reduced. material aluminiumNote: Manual measurement, there may be 1-2cm/1-3g error, which is not a quality problem.
