The HandPunch 1000 uses RSI's field-proven hand geometry biometrics technology. The terminal captures a three-dimensional image of the hand each time the employee punches. The hand's size and the shape are used to verify their identity with unparalleled accuracy. No fingerprints or palm prints are utilised. Green and red lights notify the employee of the status of each punch. There's no question any more; employees have to be there to punch.
