Story: Fujitsu's biometric scanner reads palms
0.5% is pretty good and not many access controls will allow you 2000 attempts before locking you out!
Also, I understand that the near infra-red scanner actually detects the de-oxygenated blood below the surface of the skin - and so it is not significantly affected by the temperature of the hand (there is a test on the Fujitsu web page). I guess you will alos need a live hand = so amputations is not an option. Since a person's veins are formed in the womb and do not change thereafter - it also solves the problem of children and biometrics
