How to Protect Cards From RFID Scanning
Description:
"RFID" stands for radio-frequency identification. An RFID tag is a microchip that stores information that can be read from a distance by a special device called a reader or interrogator. RFID tags are now found in some passports, driver's licenses, employee and university identification cards, and even some credit cards. The RFID tags in some of these cards can be read from up to 30 feet away, and the possibility of identity theft concerns some RFID card carriers. Fortunately, since metal effectively blocks radio waves, it's easy to retrofit a wallet to protect cards from RFID scanning. – PowerPoint PPT presentation

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.
4
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.
5
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.
6
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.
