How does the HandPunch terminal work?
The HandPunch measures the unique size and shape of the fingers and hand. Over 90 different measurements are made such as, length, width, thickness and surface area. No finger prints or palm prints are taken. To enroll an employee for the first time, the employee puts their hand into the HandPunch three times so that a CCD camera records three separate 3D images of the hand. An algorithm converts these images into one mathematical value (a template). This template is then stored in the HandPunch. Each time an employee puts their hand in the HandPunch to punch in or out of work, the HandPunch takes another 3D image of the hand, the algorithm converts this image to a mathematical value and then compares this new template with the template the HandPunch has stored previously. If the two templates match, identity is confirmed and the punch is recorded. Each time an employee punches in or out, their template is updated with each successful verification. Basically the machine learns your han
