HAND GEOMETRY
- Identification using hand geometry is fast, non-intrusive and accurate across a wide range of working conditions and skin colours.
- the geometric dimensions of the hand is used and therefore a dirty or oil-stained hand will have no effect on the accuracy of readings.
- The base plate uses silver nano-technology which has anti-microbial properties for hygiene, making them suitable in hospitals and schools.
- Hand recognition is a proven biometric characteristic and has been available for over twenty-five years.
- The 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.
- Modern hand geometry terminal are self-adjusting for age, size and texture of hands over time as well as under different environmental conditions.
- 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.
- Hand geometry readers are larger than fingerprint readers and are used primarily for physical access control and recording work time and attendance.
