Hand Geometry

Biometric systems that employ hand geometry have been in use at application sites for 20 years and are deployed successfully at thousands of locations, including welfare agencies and other government bodies, sperm banks, daycare centers and immigration facilities. Even a large university has used hand geometry for some time to ensure the integrity of its "all you can eat" meal program. A typical hand geometry identification system looks at both the top and side view of a person's hand using a video camera and compression algorithms. The reference template is an economical 10 bytes or less. Other devices look at features such as the pattern of blood vessels in the hand.
