[e-privacy] custodia per tessere e documenti con RFID

'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.'"
