Step 1

Purchase a protective sleeve. Search out companies who sell RFID signal blocking sleeves, such as RFD Shield, ID Stronghold, DIFR wear or Theft Defender (links in Resources). Choose a basic sleeve that covers debit or credit cards, an RFID-enabled identity badge or passports.

Step 2

Craft your own protective device. Make RFID-resistant duct tape by laying out a sheet of aluminum foil. Then apply strips of duct tape to the foil. Wrap the RFID-resistant tape around your wallet or whatever contains your credit or debit cards, etc., and secure with tape. Or simply wrap aluminum foil around whatever it is you want to shield.

Step 3

Purchase a protective wallet, an aluminum case or a portfolio-style device that holds a passport and multiple debit or credit cards. Visit the websites of the companies listed in Step 1 for the latest available stock. Be aware, however, that these devices tend to cost more than the simpler protective sleeves and are typically bulkier and more prone to setting off metal detectors.

Warning

Consumer Reports notes that while RFID shielding devices make it harder for snoops and thieves to read RFID transmissions from your credit or debit cards or passports, they don’t appear to block them completely and they appear to be inconsistent in their effectiveness.
