Our biometric clocking systems software is used by a wide variety of business’s and organisations large and small.

biometric hand scannerWe offer a full after sales service for all our biometric clocking systems.  We also offer a full onsite installation and after sales service.  We can offer a choice of two clocking terminals for connection to our London Clocking Systems software. Both operate in “real time” giving you accurate up to date HR attendance information to enable you to monitor  the most crucial part of your business, staff & employees.

The London Underground introduced a biometric clocking system in order to get a more accurate picture of the overtime hours being worked by it’s cleaning staff. Unfortunately the staff were in uproar and decided to take industrial action in protest, one cleaner has since been sacked for refusing to use the biometric clocking systems fingerprint reader.  The reaction by staff and employees towards biometric fingerprint devices is not new, and is based on a misunderstanding of how biometrics actually work.

Are the myths surrounding biometrics true or false!

Brief overview of the two types of biometric clocking system and how to use them..

Enrolment process for two types of biometric reader fingerprint and hand scanners.

The staff member or employee must be enrolled before they can use the biometric reader. Their details are first entered onto the clocking systems software and they are then given a pin code if pin codes are to be used. Upon first entering the pin code onto the keypad of the attendance terminal, they are prompted with visual instruction to place and remove their finger/hand on and off of the reader. This process is called enrolment and is done the first time the reader is used. The program may require up to five or more placements of the finger/hand, until it is satisfied that it has enough images to create an accurate biometric template of the person’s fingerprint or hand geometry.

Biometric Fingerprint Readers – these record the image of a person fingerprint, and then typically turns that image into an algorithm and stores it in a data file, the fingerprint image cannot then be reproduced from the data file.

Fingerprint readers can be used with or without a pin code for initial identification

With a pin code, the member of staff simply enters a 2, 3 or 4 digit pin code using the alpha numeric keypad of the clocking terminal, and then pressing the enter key, the clocking terminal then checks the biometric template stored in memory and at the same time prompts the member of staff to place their finger on the biometric reader.

When this is done an image is captured of the fingerprint and it is then compared to the fingerprint template held in the database against that pin number, if the fingerprint images match then a message appears on the attendance terminal LCD screen saying Verified – OK and the clocking terminal beeps once. If the images do not match up then a message appears saying fingerprint not recognised, and the clocking terminal beeps several times.

Without a pin code the same happens on placing the finger onto the reader. However, the clocking terminal must search through its entire database trying to find a match. So the matching process will be a second or two longer than if you use a pin code. With a pin code the correct template is identified immediately.

Biometric Hand Scanner Readers – these are always used with a 2, 3 or 4 digit pin code. Upon entering the pin code using the keypad, the staff member is prompted with a visual message to place their hand into the base of the machine, as in the video below.

The users biometric template file is then looked up, and compared to the hand geometry image that has just been taken when the user placed their hand into the base of the unit. If it matches they are given a visual/audible signal that a positive match has been made. If the match fails then a different visual/audible signal is given.
