How to Protect Cards From RFID Scanning
2
THINGS YOU'LL NEED

• Aluminum foil
• Wallet large enough to store all your RFID cards
• Heavy cardstock
• Scissors
• Duct tape or packing tape (optional)
• Credit card or similar sized card
• Pen or pencil

3
STEP 1

• Use a pen or pencil to trace the credit card onto
  the cardstock, then cut out the "dummy card" with
  scissors. Repeat this step to create a second
  dummy card.

STEP 2

• Wrap each dummy card in aluminum foil. To make
  the card easy to slide into the wallet, and to
  help hold the foil in place, you may optionally
  wrap duct tape or packing tape around the foil
  dummy cards.

STEP 3

• Open the wallet and examine how it folds up.
  Identify the card slot nearest one side of the
  folded wallet and insert one of the foil-wrapped
  dummy cards. Do the same with the other dummy
  card for the other side of the wallet.

STEP 4

• Protect cards in a wallet that opens in several
  stages by adding more strategically placed
  foil-wrapped dummy cards.

TIPS WARNINGS

• There is a small chance that radio waves from an
  unauthorized RFID reader will be able to
  penetrate the wallet edge-on, especially if your
  wallet is "fat" with lots of cards. For
  additional protection, stack all the RFID cards
  in your wallet next to each other. The RFID tags
  will interfere with each other and reduce
  readability. This technique may not render the
  tags completely unreadable, however. (Unlike
  items with magnetic coding, RFID tags will not
  damage each other if placed side by side.)
• If you have an RFID card in your wallet that you
  would like to keep readable without having to be
  removed, such as an ID badge that provides
  key-card access, place it just outside one of the
  dummy cards.
• If you keep an RFID keycard badge on a lanyard or
  clip, protect it after you leave your school or
  workplace by storing it in your RFID-proof wallet.
