•Playing Cards (2)
•Scissors
•Marker

Cut the Aluminum Foil
Take a pice of aluminum foil and set a card on one of the corners, then trace around the card. Do that 3 more times, then cut around it. Do that 1 more time.
Fold the Aluminum
Fold both pieces of aluminum along the lines.
Attach the Aluminum to the Cards
To attach the aluminum foil to the cards fold the edges around the cards.
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.
