RFID wallets function primarily as a Faraday's cage, blocking unauthorized card reading through their design rather than chemical additives. The composition of materials, such as leather, plays a role in their effectiveness, with vegetable-tanned leather containing fewer chemicals than chrome-tanned leather. However, the residual chromium in chrome-tanned leather does not impact the wallet's ability to block radio waves. A shield is typically integrated between the layers of material in these wallets to enhance protection.
