How to Protect Your Credit Cards From RFID Theft

Picture of How to Protect Your Credit Cards From RFID Theft
Most new credit cards come with 'enhanced security features.' All this does is add an RFID (Radio Frequency Identification) chip inside your card which is supposed to protect your card, but all it does is adds another thing for people to hack. All you have to do to get the information from this chip is to scan your card on an RFID reader and voilá, you have your credit card information.

To protect yourself from identity theft, I am going to show you how to make a tin foil wallet shield.

Tear off about 6 inches of tinfoil and fold it in half. (Or tear off a decent amount and measure from there)

Fold the tinfoil to the desired size (I used the size of a dollar bill).

Remember, the wider you go, the more protected you are.

You can also use your ruler to flatten it and make better folds.

Step 4: Test And Repeat

Test your sizing by putting the folded tinfoil into your wallet, measure the overhang (if any) and fold accordingly, keep testing and folding until it fits.

Step 5: DONE!
