Time Clocks and Biometric Attendance Systems are gaining popularity in the general
Time and Attendance Software market This is due to the increased security when compared
to conventional bundy clocks or punch clocks.
Biometric time clocks are without a doubt one of the most common causes of issues
when implementing a time and attendance system. Essentially this is because there
are a number of technologies available and they are not all suitable for every application.
Each of these technologies have advantages and disadvantages. Choosing the right
product for your business is critical. Selecting the wrong biometric time clock
can leave with a costly investment in a product that simply will not work in your
The Time and Attendance Consultant Buyer’s Guide to Biometric Time Clocks is a free

Using this guide will potentially save your organization thousands of dollars and
hundreds of hours of your valuable time.
Biometric fingerprint readers use the tiny ridges and valleys on your fingerprints
to store a template which represents your individual pattern. Often this pattern
uses only 10 or so of these measurement points (called minutiae) but that is sufficient
to form a unique mathematical representation (algorithm) which will identify you
as an individual.
Biometric Time and Attendance systems use fingerprint readers to record when employee
start and finish work. Fingerprint readers are most commonly used when there is some
concern that employees may be clocking in and out for each other in a conventional
time card or manual system.
Employees may be concerned when biometric time clocks are introduced due to the common
misconception that the fingerprint templates could be stolen and used against them.
This is exceptionally unlikely as only a very small percentage of the fingerprint
is used and this cannot be reverse engineered into the original fingerprint.
Biometric Hand scan readers use the geometry of the users hand to store a template.
The width of the hand the length and width of the fingers are all elements used in
There are sufficient differences in these physical characteristics between users
and in combination they provide a very accurate an quite trouble free method or recognition.
Unlike other fingerprint time clocks which are subject to fingerprint damage, poor
recognition speed or a prohibitive pricing model , hand scan are an extremely attractive
This is not to say that the hand punch is without issues- the unit is very subject
to dust ingress and mechanical damage. This can be overcome to some degree with an
optional dust cover but the reliability of the unit is heavily dependent of the application
is is used in.
