Pickpocketing just got a lot nerdier. Instead of having to master the art of deception and sleight-of-hand, hackers have found a new way to do it through the air.
Modern "wave-and-pay" credit cards (the ones that you don't have to swipe) work by transmitting credit card information by radio frequency identification.
All that hackers have to do is get a RFID card of their own.
There's a catch, though, and it's that hackers can only steal the information if they sneak the RFID reader within 6 inches of the card.
