Biometric Hand Recognition

Biometric hand geometry recognition measures and analyzes the physical attributes of a person's hand. Characteristics measured include the overall size and shape of the hand, including the lengths of the fingers and joints, and characteristics of the skin such as creases and ridges.

Hand recognition systems are fairly common, however they are expensive due to the proprietary hardware and not that accurate compared to other technologies.

To prevent fooling the system: No precautions needed as it is believed to be too difficult to create a "fake" hand that has all the physical attributes needed.
