HandPunch 2000 is a technology that uses the size and shape of the human hand to verify a person's identity. It does not read fingerprints or the palm. The reader takes over 90 measurements of the fingers and part of the hand. The hand reader uses invisible light like the kind used in a television remote control, special optics and a CCD (chip) camera to capture a three-dimensional image of the hand. Using advanced microprocessor technology, the terminal converts the image to a template. It stores the template in a database with the employee's ID number. To punch in, the employee enters his or her ID number at the terminal. HandPunch 2000 prompts the employee to place his or her hand. The terminal compares the hand on the platen with the employee's unique template.
