Hitachi's Vascular Pattern Recognition (VPR) is gaining acceptance as a new biometric. The Hitachi readers use LEDs to scan the vein patterns in an individual ’ s finger. The result is said to be more accurate – and more sanitary – than commonly used Hand Geometry Readers.
Hitachi brought these readers to market in 2004, and they are widely used in Japan. According to a recent article in the Times Online, the readers are making serious inroads into the European market, as well.
That being the case, you should expect to see VPR showing up in U.S. security markets before long.
Not only is VPR being touted as more accurate than other biometrics, it is supposedly much harder to counterfeit.
The natural question arises — What happens if I use this technology and someone steals my finger? Well, as blood leaves the finger, the veins collapse and their pattern becomes unreadable. Of course, that would be little comfort to you unless you could convince a robber of this fact before he lifted your finger.
