Why people are wrapping car keys and wallets in aluminum foil; what is the reason and does it really work?

Similarly, wallets containing contactless cards can be shielded from unauthorized scanning. While effective, aluminum foil offers only partial protection against signal theft. Stronger security measures remain essential for comprehensive protection against modern threats.
