The tin-foil hat contingent may have finally hit on something right.

There’s a simple solution to the threat of thieves stealing no-swipe credit cards.

A BoingBoing reader sayeth, “The radio signal can be easily blocked with as little as a sheet of tinfoil or the anti-static material (like what an EZ-Pass ships in.) Putting a bit of foil or anti-static material between your card and the outside of your wallet will block potential ID thieves.”

You could even take it a step further and make a whole anti-RFID wallet.

This is all thanks to the relatively weak power of RFID tags, the transmitor broadcasts the credit card information. It still won’t prevent the CIA from mind-raping you.
