KO-HK2 Biometric Plam Reader Time Attendance

HandKey2 Description
The HandKey II is Recognition Systems' fourth generation biome
tric access control
Hand Reader1. The Hand Reader records and stores the three-d
imensional shape of the
human hand for comparison and identity verification. Upon verifi
cation, the Hand
Reader produces an output that can unlock a door, send card for
mat data to an access
control panel, or communicate with a host computer. The Hand
Reader also has
auxiliary inputs and outputs that can be used to control other sys
tems such as CCTV
cameras and alarms.
HandKey2 Biometrics
Biometrics is a term describing the automatic measurement and
comparison of human
characteristics. While its origins are ancient, the evolution of adv
anced scanning and
microprocessor technology brought biometrics into everyday life.
Electronic hand
geometry technology first appeared in the 1970s. Recognition Sy
stems Inc., founded
in 1986, built the first mass-produced hand geometry readers an
d made biometric
technology affordable for the commercial market. Today, Recog
nition Systems'
products are in use in every imaginable application from protecti
ng cash vaults to
verifying parents in obstetric wards.
HandKey2 Principle of Operation
The Hand Reader uses low-level infrared light, optics, and a CC
D (IC chip) camera to
capture a three-dimensional image of the hand. Using advanced
microprocessor
technology, the Hand Reader converts the image to an electroni
c template. It stores the
template in a database with the user's ID number.
To gain access, the user enters his or her ID number at the Han
d Reader's keypad or
uses an external card reader. The Hand Reader prompts the use
r to place his or her
hand on the reader's platen2. The Hand Reader compares the h
and on the platen with
the user's unique template. If the images match, the Hand Read
er unlocks the door or
sends the user's ID number to a third-party access control panel
for processing.
