9 thoughts on “Microwaving RFID cards

  1. Rather than microwave it, I wrote to Washington Mutual and told them I didn’t want a card like this and to send me a new one. They told me they’d send a new card, but instead they canceled my current card and when I complained waited two days to contact me to tell me to I should reorder a new card, and when I told them they’d crossed the line and I was closing my account they said, “Sorry to see you go.” http://mypersonalhothothot.blogspot.com/2008/06/washington-mutual-paypass-rfid-debit.html

  2. I wonder if it would be possible to make a card wallet which would block the RFID signal, only making the card accessible when you take it out. This would make things much safer.

  3. Are you guys being a little paranoid? These RFID only have a range of about 2 feet. The greatest distance I have see was about 20 M. The surface area for that was about the size of my small tablet computer. However, it was interesting to see the microwave results (I was hoping for a video)

  4. mesoiam: Yes, if you just wrap the card in tin-foil (!) it should block it from working. You can already buy shielded wallets, I’m told, though I’m too lazy to go google them right now. I have definitely seen ads for RFID-shielded passport holders, and I’m pretty sure the same company makes regular wallets of similar design. It certainly shouldn’t be difficult to do.

  5. I’ve nuked a card like that before, though mine looked a lot worse afterwords, and i had to clean melted plastic splatter out of my microwave, and there was so much thick black smoke it filled the kitchen, and i had to open all the windows to air it out, but the light given off by the card was so bright and amazing, i cant say i wont ever do it again.
