Here, there, and everywhere
Don't carry RFID? You might be surprised; the short-range ID technology is currently found in everything from US passports to swipeless credit cards to public transit passes to World Cup tickets to car keys to the building access pass for your office building. A few of the digerati even elect to have RFID implants from VeriChip slipped beneath their skin in order to use them as cashless payment systems.
Much of the information on these chips can be read without exotic equipment, assuming an attacker can get within several feet with a concealed RFID reader. Unfortunately, most tags give users no control over when they respond to queries, and they offer no notification, which means that sensitive data could be at risk in public places.
The solution, for those concerned about such things, has so far been low-tech: smashing the chip with a hammer appears to be the preferred method for passports, but it is technically illegal and could lead to unpleasantness at customs.
