RFID Security Breech Credit Card

The tin foil hat brigade was onto something, just cut a piece of aluminum foil 3 to 4 times the height of your wallet then fold it to the appropriate size and put it in the bill compartment. To test it out place your wallet (must have an RFID equipped card inside) next to the appropriate type of scanner (credit card, bus pass. etc) if it beeps the foil isn't thick enough. If it doesnl't beep you should be ok.
