These days credit card information can be taken from you by anyone with a RFID scaner. So lets MacGyver up a RFID signal blocker.
Step 1: Things You Will Need
You will need:
•Aluminum Foil or Copper Mesh (copper mesh is found in the glass of a microwave door)
•Playing Cards (2)
Step 2: 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.
Step 3: Fold the Aluminum
Fold both pieces of aluminum along the lines.
Step 4: Attach the Aluminum to the Cards
To attach the aluminum foil to the cards fold the edges around the cards.
Step 5: 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.
Step 6: 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.
