Does aluminium foil block RFID scammers?

A viral trend claims wrapping wallets in aluminium foil protects RFID-enabled cards from digital pickpockets. While foil can block some signals, experts note limited effectiveness due to gaps and that contactless cards transmit minimal data. RFID skimming is rare. Specialized RFID-blocking wallets are recommended over foil, along with monitoring bank statements and transaction alerts for fraud prevention.
