My wife bought me a cool Muradin RFID-blocking wallet for Christmas. I like it a lot, except for the fact that it doesn’t actually block RFID if you use it as advertised.

The wallet has a roomy inside “cage” for storing cards, and an external pocket for storing your “frequently used card”:

That’s not just my interpretation of the photo. The site goes on to explicitly say that the outside pocket is for your card:

A credit card in the "FUC (frequently used card) exterior pocket"

But what does our handy dandy Flipper Zero think of the wallet’s claim? Not much. It had no trouble reading the numbers off my debit card in the “FUC exterior pocket”:

To see if orientation mattered, I rotated my card 180º and tried again. It didn’t matter:

I went on to test with single cards inside the inner compartment. If the card was against the back of the wallet, as far as possible from the protective flap, the Flipper Zero couldn’t detect it.

If the card was on top of some non-RFID contents, like a few folded dollar bills, so that it was about halfway down inside the inner compartment, I could tell with about 90% reliability whether the card was a Visa or American Express:

A Visa card is inside the wallet. Now an American Express card is inside the wallet.

If the card was on top of several pieces of non-RFID content, and pushed up to the top of the inner compartment, I could scan its number through the “RFID-blocking” wallet about 50% of the time, depending on the card.

This wallet doesn’t work. Its RFID-blocking claim is somewhere between misleading and an outright lie. Don’t buy it.
