Experts Explain Aluminium Foil Use to Block RFID Signals in Wallets
Videos showing people wrapping wallets and cards in aluminium foil to block wireless theft have gained popularity on social media. This method leverages aluminium's conductive properties to act like a Faraday cage, potentially blocking RFID and NFC signals used by contactless cards and identity documents. Experts note that while this can reduce signal transmission if done without gaps, it is not a foolproof or permanent solution. Most contactless cards already include security features and operate over very short distances, limiting unauthorized scanning risks.
