Researchers at Tokyo-based Hitachi Ltd., are developing a biometric device that would identify a driver by reading the veins in his fingers. Each finger could authorize something different, for instance, one finger could authorize the driver to start the car, another finger could be scanned to adjust the seat or mirror and yet another finger could authorize the payment for a hamburger at a drive-through, according to Hitachi. The company would not divulge how soon the technology might be fitted into automobiles coming off the production line, however a spokesman did say that Hitachi is working to commercialize the biometric technology and that it will start with the automotive industry. The finger-vein reader, similar to the more well-known fingerprint reader, works by matching up the veins in the driver's finger to corresponding information stored in the device's database. The scanner reads the finger-vein pattern by passing light through the finger.
