By the sounds of things, this is something that Fujitsu has been developing for a while. But with all the paranoia currently sweeping the nation about identity theft and card cloning, now seems like a good time to launch the product. Using infrared light scanning the palm vein reader can create a map of individuals’ hands, checking the unique vein layout to identify users. Wave your hand over the scanner and your veins will send back a black reflection. Data about your hand layout can then be stored on computer or on your bank card, ensuring that it’s you using your card and no one else. Surely one of these technologies is going to be adopted by banks eventually? We’re rather taken with the idea of having to say how do to your ATM. The company’s showing off the technology at CeBIT this week.
