Principle of
Operation The HandPunch uses low-level infrared light, optics, and a CMOS (IC
chip) camera to capture a three-dimensional image of the hand. Using
advanced microprocessor technology, the HandPunch converts the
image to an electronic template. It stores the template in a database
with the user’s ID number.
To gain punch, the user enters his or her ID number at the
HandPunch’s keypad. The HandPunch prompts the user to place his or
her hand on the HandPunch’s platen

. The HandPunch compares the
hand on the platen with the user’s unique template. If the images
match, the HandPunch records the transaction for processing.
The
HandPunch
Terminal The HandPunch is a time and attendance terminal designed for use
with time and attendance software.
Refer to Figure 1-1 on page 5 when reviewing the information in this
section.
The HandPunch has an integrated keypad for ID entry (see Figure 1-1).
The and keys are used for data entry and
programming.
Four different features assist the user with hand placement and read
verification.
1. A light emitting diode (LED) hand placement display on the Hand-
Punch’s top panel assists users with hand placement on the platen.
2. A liquid crystal display (LCD) shows operational data and program-
ming menus.
3. “Red light/Green light” verification LEDs quickly inform users if their
verification attempts were rejected or accepted.
4. An internal beeper provides audible feedback during keypad data
entry and user verification.
1. The Platen is the flat surface at the base of the HandPunch (see Figure 1-1).
This is where users place their hands for enrollment and verification. It has
guide pins to assist positioning the fingers during use.
