Many credit cards use radio-frequency-identification technology. This technology wirelessly transmits your credit card information to the reader, which lets you simply run your card over the reader instead of swiping. While it may save you time, this technology also puts you at risk from thieves that use homemade readers to scan your wallet and collect your credit card information. Reduce this risk with some do-it-yourself techniques at home.

Basic Credit Card Protection

Remove all of the credit cards from your wallet. Store any credit cards you do not frequently use in a safe place inside your house, such as a fireproof safe. Keeping unused credit cards at home will reduce your risk of theft.

Place the remaining credit cards back in your wallet with the magnetic strip facing the inside of the wallet. Having the front of the credit cards facing the outside of your wallet may make it more difficult for a scanner to identify the radio-frequency-identification chip.

Store your credit cards together in your wallet. If your wallet contains multiple areas for credit cards, store your cards in one area. Storing them together may make it more difficult for a scanner to differentiate the information between the credit cards.

Advanced Credit Card Protection

Open your wallet and lay it flat against a smooth, flat surface. Use the tape measure to measure the length and width of the extended wallet. Write down the measurements. Experts suggest wrapping your wallet in aluminum foil as metal helps block electronic scanners. Knowing your wallet's measurements will allow you to create a shield using aluminum foil.

Cut a piece of aluminum foil twice the length and width of the extended wallet. Lay the piece of aluminum foil on a smooth, flat surface.

Fold the aluminum foil in half lengthwise. Fold the aluminum foil in half width wise. This will create a double layer of aluminum foil the size of your wallet.

Cut small pieces of duct tape. Apply the duct tape along the edges of the aluminum foil.

Place your wallet on top of the aluminum foil with the inside of the wallet facing you. Press the edges of the duct tape around the inside edges of your wallet to create a seal. Ensure the aluminum foil completely covers your wallet. Place your credit cards inside.


  • Check your credit report and credit card statements often for fraudulent activity. Report any fraudulent activity to your credit card provider immediately.

    Consider purchasing a RFID-blocking wallet. These wallets use special materials to help block scanners from accessing your information.
