We actually have a tinfoil-lined ten-gallon-hat here in the Gadget Lab office into which we toss items which prey on paranoia. You know the kind of thing: radiation-eating cellphone cases and “reports” on the dangers of Wi-Fi both feature heavily. And you might think that the Flipside wallet, a radio shield for credit cards, might end up in the Hat of Shame.

But sometimes the paranoia is justified, and when it comes to RFID, paranoia of Philip K. Dickian proportions is quite appropriate. You see, governments and credit card companies think it’s OK to store your sensitive information on these easily readable chips, at the same time sticking their heads into a huge pile of sand. The problem is that RFID is far from secure, and can be hacked and read easily from afar.

So, along with mesh Faraday cages for the newer, more “secure” passports, we’re actually pretty interested by the Flipside. The polypropylene clamshell case will hold seven cards (or six and a sentimental photograph), plus 15 US bills (other bills may need to be folded to fit). Inside the compartments are divided into a cash side and a card side. The cash side does without the aluminum shielding so you can keep a bus or toll pass in there and offer it to a chip-reader while the other cards remain safe. $40.
