There are several branded aluminium wallets currently on the market. Aluma Wallet appears to be the most active brand, with infomercials, press and appearances on morning TV shows. There are also AlumaWallet review websites that document varied customers feedback on aluminium wallets.
At ARMOURCARD, we applaud Aluma Wallet for advertising the vulnerabilities of RFID and that they are helping to educate the public to this vulnerable wireless technology. However we just believe that passive shielding or blocking (lack of) technology like these wallets use do not offer the best protection, if any at all.
