Pay at your table with Ingencio's Bluetooth credit card machine

A company called Ingencio is pushing a new wireless credit card machine (with built-in Bluetooth) that lets customers at restaurants (or just about anywhere else) swipe their cards themselves when it's time to pay. It's supposed to cut down on a practice called "skimming", where waiters or whoever at restaurants or stores sneakily run your card through a magnetic reader that copies down all of the information on your credit card, including the special numbers and codes that aren't printed on the card itself. You better hope that it uses some pretty strong encryption or else it'll be a field day for thieves — or at least the ones who are smart enough to do a little Bluetooth hacking.
