The HandKey reader by Recognition Systems, Inc. utilizes field proven hand geometry technology that maps and verifies the size and shape of a person's hand all in less than one second. The HandKey captures a three dimensional image of the hand using a 32, 000 pixel image array. The 90 measurements including the lengths, widths, thickness and surface area of the fingers and hand are taken. The advanced algorithm determines the unique aspect of the hand and then generates a nine-byte hand template. This template is then stored and used for subsequent comparisons. Dirt, cuts and abrasions on the hand have no impact on accuracy.
