I have an American Express Blue card which includes an RFID chip (because waving your card is so much easier than swiping it.) Unfortunately, if you have one of these (or a credit card with PayPass) your card is vulnerable.
Fortunately, it’s easy to disable the RFID chip in your credit card. Here’s what I do:
- Locate the chip – this is easy with my card since it is transparent and I can see the chip. If your card isn’t transparent, the chip can be located by finding a slight divot in the plastic (usually on the back.)
- Stab the chip a few times with a sharp object – I use my trusty Leatherman Super Tool, but any sharp object will do. I stab from the back of the card because there’s less plastic to go through to get to it. As you stab the chip, you’ll feel some crunching or grinding. If you don’t then you probably missed the chip.
- Now you can walk around confident your credit card information can’t be read over the air by some nefarious evil doer.
