SUMMARY
RFID scanners can indeed capture information from RFID-enabled cards in wallets, making them vulnerable to unauthorized access. Aluminum and other metals can effectively block RFID signals, functioning similarly to a Faraday cage, which prevents electromagnetic signals from penetrating. This method is a practical solution for protecting sensitive information stored in RFID cards. For optimal protection, users should consider using aluminum-lined wallets or pouches specifically designed for RFID shielding.
