Introduction

Biometrics is a term describing the automatic measurement and comparison
of human characteristics. While its origins are ancient, the evolution of
advanced scanning and microprocessor technology brought biometrics into
everyday life. Electronic hand geometry technology first appeared in the
1970s. Schlage Biometrics Inc., founded in 1986, built the first mass-produced
hand geometry readers and made biometric technology affordable for the
commercial market. Today, Schlage Biometrics’ products are in use in every
imaginable application from protecting cash vaults to verifying employee
attendance in hospitals.
The HandPunch uses low-level infrared light, optics, and a CMOS 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 along with the user’s
ID number.
To gain punch, the user enters his or her ID number at the HandPunch’s
keypad or uses an external card reader. The HandPunch prompts the user to
place his or her hand on the HandPunch’s platen
1
. The HandPunch compares
the hand on the platen with the stored user’s unique template. If the images
match, the HandPunch records the transaction for processing.
The HandPunch is a time and attendance terminal designed for use with time
and attendance software. Refer to “Figure 1-1” on page 5 and “Figure 1-2” on
page 6 when reviewing the information in this section.
The HandPunch has an integrated keypad for ID entry and reader
programming. The HandPunch 3000 has two function keys (F1 and F2 – see
Figure 1-1). The HandPunch 4000 has ten function keys (F1 through F10 –
see Figure 1-2). These function keys can be programmed to collect data or to
activate auxiliary outputs. The
CLEAR
and
ENTER
keys assist in data
entry and programming.
