Hand Geometry Terminals
Hand geometry terminals are one of the original biometric technologies to enter the time and attendance market in the 1970s. Little has changed with the technology since its first introduction because its simplicity is its strength. Unlike more modern biometric technologies that are capable of identifying a fingerprint or face amongst thousands of templates (1:n), hand geometry terminals verify the hand placed on the platen by comparing it against just one record – the hand template recorded for the PIN entered.
There is effectively only one hand geometry terminal which dominates the market which the HandPunch. Multiple versions of the HandPunch are available which vary by capacity and communication technology.
