Hand recognition is a proven biometric characteristic and has been available for over twenty-five years. To achieve personal authentication, a system may measure either physical characteristics of the fingers or the hands. These include length, width, thickness and surface area of the hand.

Hand geometry systems use an optical camera to capture up to 90 or more key points on the palm and sides of the hand including finger width, height, and length; distances between joints; and knuckle shapes. Multiple measurements offer reliability and relative ease of use and make this biometric system suitable for large organisations with high volumes.

Hand Geometry is one of the most reliable biometric characteristics because the shape and size of our hands are surprisingly distinctive and remain relatively stable over time. Modern hand geometry terminal are self-adjusting for age, size and texture of hands over time as well as under different environmental conditions.

Hand geometry readers can function in extreme temperatures and are not impacted by dirty hands (as fingerprint sensors can be). Hand geometry devices are able to withstand wide changes in temperature and function in a dusty environment. They are commonly used for access control to facilities and time & Attendance.

Major benefits of hand geometry are that it is fast, non-intrusive and accurate across a wide range of working conditions and skin colours.

Hand geometry readers are larger than fingerprint readers and are used primarily for physical access control and recording work time and attendance.
