Biometric Characteristics
Hand Biometrics
How does Hand biometric work?
Hand biometric works as the user places his or her hand on the reader's surface and aligns it with the guidance pegs then measures and analyzes the overall
structure, shape and proportions of the hand:
- length
- width
- thickness
- characteristics of the skin surface such as creases and ridges
Then the device checks its database and if a match is found, assess will be granted.

How is this technology being used?
Access control:
- monitor payroll accuracy and access control
- United States military has been using hand recognition geometry for access control.
- Majority of the nuclear power plants in US use hand recognition geometry for access control
Time and attendance:
- a product designed to keep track of employee's attendance hours is TimeClock Plus' GTs
- the employee will put his/hers right hand on the scanner and the system will perform a scan through the databases and if a match is found, access will be granted and the time will be recorded down
Visitors management:
- Used during 1996 Olympic Games where access to and from the Olympic Village was controlled using hand recognition geometry
- San Francisco International Airport uses hand recognition geometry to restrict access to critical areas
- The Fastgate (INSPASS) pilot program employs hand recognition geometry systems to track border crossings for frequent travelers
- verify identity of parents at Child day care centres
