How to Fight RFID Snagging

You've already heard about how RFID snaggers can get your personal (and credit card) information without your knowledge. How do you prevent this from happening? Most people find that a tin foil wrapper will keep your data secure. You can make a tin foil wallet, or wrap your entire body in foil. If aluminum foil is not your thing (perhaps that's why aluminum prices have been rising), you can build your own "jammer". See how to build an RFID firewall. This is not a project for beginners.
