Biometric Time Clocks

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 available in the following broad technologies. Each of these technologies has its own advantages and disadvantages. The Time and Attendance Consultant’s Guide to Biometric Time Clocks has a great deal more information to assist with the evaluation of these technologies.

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 business environment

The Time and Attendance Consultant  Buyer’s Guide to Biometric Time Clocks is a free publication which you can get simply by subscribing to our Free Tips Series. This guide offers detailed information regarding all the most common biometric alternatives. 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 this process.

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 alternative.

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.
