When you first think about biometrics devices you probably think about fingerprinting, eye scanning or perhaps facial recognition. But there are other unique biological signatures that devices can use for identification. Case in point: Fujitsu's PalmSecure, a device that verifies your identity based on the vein patterns in your palm.
As with fingerprints, your vein patterns are unique. PalmSecure is a device that can read these patterns by radiating your palm with near-infrared rays. This method is not just more hygienic than fingerprint scanners that require physical contact with the scanner, but it is also believed to be more secure, since vein patterns are located under the skin and are therefore more difficult to forge.
