Some of the top RFID blocking wallet products today are made with metal materials. A steel or aluminum body may be used on your wallet. With this, you will secure your cards inside of a container. The metal will surround those cards. This can include a securing lock that keeps the wallet secured all the way.
The surface will block RFID readers from getting access to your cards. Metal materials create sturdy barriers where outside signals cannot get into your cards. This, in turn, keeps your cards protected. A metal wallet is appealing for being a practical solution with a slim minimalist front pocket design.
