RFID Cards to Include Tin Foil Hats?
An anonymous reader writes "The tinfoil hat finally gains government approval. From the story: 'Wrap an RFID chip [of the US passport] inside a Faraday cage, and the electromagnetic waves from the chip reader can't get in and activate the chip. The State Department says it may use the principle to give travelers an added sense of security. No, there won't be rolls of aluminum foil included with every passport. Instead, the passport cover may include a network of wires woven into the fabric. Fold the passport shut, and there's your Faraday cage. Even Schneier agrees that a properly shielded passport cover should solve the problem. He wonders why this wasn't included in the original plans for the new passports. 'It took a bunch of criticism before they even mentioned it,' Schneier said. And he hopes the anti-snooping technology is thoroughly tested before the new passports are introduced next spring.'" We've also seen this suggested in the past.
It means metal detectors will find your passport cover. When I go through airport security, I get wanded and they look in my wallet, which bugs the heck out of me. I usually carry my passport and cash in a nylon neck pouch though, and that doesn't set off the metal detectors. I don't like the sound of this new wire mesh thing. Big Brother and for that matter any club or courthouse I might visit has no need to know whether I'm carrying a passport.
