Travellers Wrap Passports in Foil to Block RFID Scanning
Some travelers are wrapping their passports and wallets in aluminum foil to stop unauthorized scanning of their personal data.
This trend is driven by concerns over RFID chips in passports and contactless cards, which can be read wirelessly.
The foil acts like a shield, blocking the radio signals that read these chips.
However, experts say this protection might not be necessary because the chips are usually not accessible unless the passport is open.
Also, foil can be impractical as it tears easily and is inconvenient to use frequently.
Official agencies do not endorse this method, but travelers can use RFID-blocking covers and wallets for better protection.
Travellers are wrapping passports and wallets in aluminum foil to block RFID signals.
RFID chips in passports store personal data like biometric information and passport numbers.
Foil acts as a Faraday cage, blocking radio signals that read RFID chips.
Experts argue that foil wrapping is often redundant and impractical for frequent use.
Official agencies do not endorse foil wrapping, but RFID-blocking covers and wallets are available.
