How To Block RFID From Reading Your Credit Card?


How To Block RFID From Reading Your Credit Card?
Step 1
Wrap your credit card in aluminum foil. The aluminum foil shields the credit card from RFID signals. You can also place the credit card in a container made from a conducting metal.

Step 2
Purchase an RFID-blocking wallet. Many companies sell shielded wallets, which are lined with aluminum or another conducting metal. The metal shields your credit card from RFID readers when your wallet is closed.

Step 3
Hold the credit card in your fist. The RFID signals can’t travel through the saltwater in your body. You can also immerse the credit card in saltwater to prevent RFID readers from reading it. Of course, this is less practical.

Step 4
Contact your credit card company and ask for a credit card without RFID if you never want to use contactless payments. If your credit card company won’t give you a card without an RFID chip, you can permanently disable the RFID chip on your credit card by smashing the chip with a hammer. You won’t be able to use contactless payments without getting a new credit card.

If you have multiple credit cards with RFID chips, you can stack them on top of each other in your wallet. Multiple RFID chips close together can confuse RFID readers.
