For years, biometric finger scanners have been used in ATMs and at the cash register. But there are problems with finger scanners. Researchers have demonstrated how a flat photograph or molded fingertip can easily fool these devices into giving a false approval. And while face recognition is improving, especially 3D facial mapping, these devices aren't yet in wide use today.
Fujitsu PalmSecure is another option. Already in use in hospitals and government offices, the device reads the hand's vein pattern using near-infrared light. This week, CNET's Robert Vamosi talks about the technology with Joel Hagberg, vice president of marketing and business development at Fujitsu Computer Products of America. Because PalmSecure reads the blue blood veins, Hagberg argues the system can't be defeated.
