Differentiates 3D Finger Images
A 32,000 pixel CCD (Charged Couple Device - a semiconductor
device that reads images electronically) digital camera inside
the unit infers the length, width, thickness and surface area
of the hand and fingers from silhouetted images projected
within the scanner. Many of the finger's measurements are
taken and the characteristics are represented as a 20 byte
template. Therefore keys and cards are not needed, and only
lightly placing your hand into the unit will complete verification.
Simple and Easy Operation
The GeoKey is designed for simple, clear and quick operation,
and is suitable for placement of either the left or right
hand.
One Person - Two Templates
When enrolling, you choose between entering templates of
just one hand or of both hands. If both hand's finger images
are entered, then should one hand be injured, the other can
be used without any problem.
Safe and Reliable
Finger image templates are regarded as extremely reliable
in that they do not suffer significantly from template aging,
where people's biometric data changes over time, and sample
taking is not affected by whether the users fingers are too
damp or too dry. Furthermore, the GeoKey has a self learning
feature in which it will record a finger image's changes over
time, so should a user's fingers get fatter or thinner over
time, then the GeoKey will automatically adjust its settings
to allow for this.
No Infringements on Personal Rights
The GeoKey does not make a recorded image of a person's
finger, much less a fingerprint. It simply takes measurements
of the finger's height, width and length etc and records them
into a 20 byte template. As a result there can not be any
infringement of a person's personal rights.
Ability to Work in a Network
The GeoKey itself already contains more than enough features
and control procedures to work as a stand alone unit, which
can be used in an area where the number of users is relatively
small. As to a larger system involving larger numbers of people
and more doors of entry and exits, the GeoKey has the ability
to be linked in a series of units under the same administration.
Under the system, the user only needs to enroll in one unit,
and afterwards the template is transmitted to all of the units,
and so the user can gain access to any of the other units.
Computer Administration
By a number of different possible link modes, a central
PC system can control and administer settings to each GeoKey
in its system, including finger templates, statistics and
log analysis. In this way the system can be administered more
efficiently and effectively.
Remote Control and Administration
Either through the central command unit, or through direct
line cable, telephone cable or ether net link, a PC can operate
remote control and administration to a GeoKey unit.
Simple Convenient Installation
The GeoKey has been designed so that it can be installed
onto a table, hanging on a wall, or actually built into the
wall.
Multi-Input, Output Mode
Can support four different inputs, four different outputs,
and can also test for misuse of the system and door state
signal. Is extremely convenient to use with all types of input
and output equipment.
Use in Conjunction with Other Systems
Through its multi input output mode the GeoKey can be linked
with various external systems, including door lock systems,
attendance record systems and identification systems to form
part of a comprehensive, safe and reliable system.
Several Attendance Record Methods, Fair and Just
There are a number of ways in which the GeoKey can be used
for attendance records, and unlike the use of cards or keys
using the GeoKey ensures that only the ral user's records
will be recorded, and not an imposter, thus ensuring a safe,
reliable and fair system.
