Call it high-tech hijacking. Thieves now have the capabilities to steal your credit card information without laying a hand on your wallet. It's new technology being used in credit and debit cards, and it's already leaving nearly 140 million people at-risk for electronic pickpocketing. It all centers around radio frequency identification technology, or RFID. It's supposed to make paying for things faster and easier. You just wave the card, and you've paid. But now some worry it's also making life easier for crooks trying to rip you off. In a crowd, Walt Augustinowicz blends right in. And that's the problem. If I'm walking through a crowd, I get near people's back pocket and their wallet, I just need to be this close to it and there's [their] credit card and expiration date on the screen," says Augustinowicz demonstrating how easily cards containing RFID can be hacked. Armed with a credit card reader he bought for less than $100 on-line and a netbook computer ... for about an hour he patrolled Beale Street, looking for RFID chips to read, and credit card information to steal. Even scarier, Augustinowicz says bad guys could work a crowd, stealing numbers and then e-mail them anywhere in the world. It's not just your credit and debit cards at-risk. While they are harder to hack, all US passports issued since 2006 contain RFID technology that can be read, and swiped. "It gives me a lot of personal information like your date of birth, your photo if I wanted to make some sort of ID," said Augustinowicz demonstrating with his reader.
