Inner layer made of a special metal alloy that blocks RFID waves and frequencies. This layer is found between the lining and the leather (called Intra-lining). The Intra-lining is super thin, meaning you won't even know it's there, and will not impede on the integrity of the wallet. This allows easy access to credit cards or passports as the wallet was designed.
Cabrelli & Co. wallets now have "built-in" ID Defender Technology which make "smart" cards virtually invisible to radio wave scanners. RFID chips can typically be read through bags, wallets, clothing and more. Protect your information. Cabrelli's new ID Defender shielding technology blocks this transmission from happening as long as the card is in the wallet.
