People Wrapping Wallets in Aluminium Foil to Block Wireless Theft

People are wrapping their wallets in aluminium foil to protect their personal information from being scanned wirelessly.

This method blocks radio-frequency signals, making it harder for RFID readers to communicate with the chips inside the wallet.

While it's not a perfect solution, it adds an extra layer of privacy.

Some government-issued IDs can be read from far away, posing a greater privacy risk than bank cards.

However, the risk of wireless theft is relatively low, and aluminium foil is not foolproof.
