Tape the Cards Together

Tape the two cards together with the playing cards on the outside. Make sure that you dont tape the top, you will still need a side to put your credit card in.

Information

1. The more aluminum foil you add the more amount of the signal will be blocked to a point, but copper mesh will protect it more than aluminum foil.
2. This will somewhat protect your card from people caring RFID scanners.
3. This will only somewhat protect a credit card if it has a RFID chip in the card. If the card does not have a chip than there is nothing for a RFID scanner to detect.
