The RFID Hacking Underground.

They can steal your smartcard, lift your passport, jack your car, even 
clone the chip in your arm. And you won't feel a thing. 5 tales from the 
RFID-hacking underground.

James Van Bokkelen is about to be robbed. A wealthy software 
entrepreneur, Van Bokkelen will be the latest victim of some punk with a 
laptop. But this won't be an email scam or bank account hack. A skinny 
23-year-old named Jonathan Westhues plans to use a cheap, homemade USB 
device to swipe the office key out of Van Bokkelen's back pocket.

I just need to bump into James and get my hand within a few inches of 
him," Westhues says. We're shivering in the early spring air outside the 
offices of Sandstorm, the Internet security company Van Bokkelen runs 
north of Boston. As Van Bokkelen approaches from the parking lot, 
Westhues brushes past him. A coil of copper wire flashes briefly in 
Westhues' palm, then disappears.

Van Bokkelen enters the building, and Westhues returns to me. "Let's see 
if I've got his keys," he says, meaning the signal from Van Bokkelen's 
smartcard badge. The card contains an RFID sensor chip, which emits a 
short burst of radio waves when activated by the reader next to 
Sandstorm's door. If the signal translates into an authorized ID number, 
the door unlocks.
