What is a Biometric Time Attendance System?
A Biometric time and attendance system is an employee clocking solution that not only ensures workers can be tracked accurately, and therefore paid for the correct amount of hours, but removes the risk of "buddy clocking" by using physiological recognition methods to verify a particular individual. In a matter of seconds, a member of staff can be recognised, clocked in or out, and have their on-site whereabouts confirmed. These methods are completely safe and data can be stored in numeric codes instead of recognisable patterns to increase confidentiality.
An added benefit of biometric systems is that they can also be set up to improve workplace security when installed across different parts of a site, allowing access into certain areas only to accredited individuals. In the case of time and attendance software, it is likely that only verification, not identification, will be required: an employee is matched against the relative record within the HR database, and their presence on-site is recorded by the system.

So what types of biometric recognition are available to businesses in the UK, and how does each type work in the context of time and attendance?
Face recognitionFacial recognition software works by identifying individual facial characteristics such as the amount of space between the eyes, position of the nose, cheekbones and jaw line. Widely used for security purposes, its adaptability to clocking in and out processes makes it a good choice for workforce time-keeping and attendance management. Recognition takes place very quickly, usually within a couple of seconds, and this type of biometric system is more hygienic than fingerprint and hand scanners.
Fingerprint recognitionThis is the most common type of biometric system, and fingerprint scanners are now common in many walks of life. A fingerprint scanner will compare the ridges and furrows present on an individual’s fingertip to their record in a database, and verification/identification takes place within a few seconds. Ease of use and fast recognition makes this type of biometric software popular with all sizes of business.
Retina and iris scanningBlood vessels at the back of the retina are unique to each individual, and a retina or iris scan will take around 15 seconds to complete. Iris recognition is generally considered to be the most accurate method of verifying an individual, although as a concept, it is relatively new. Blind people can use this technology as it is not sight-dependent. Even identical twins do not have the same iris 'pattern'.
Voice recognitionVoice recognition is occasionally used for workforce management, but performance of these systems can be hit and miss, depending on the audio quality. The user listens to a series of words or numbers and then has to repeat it. An individual’s acoustic patterns are unique, and these are picked up by the voice recognition software along with any present dialect or accent.
Hand geometry recognitionThis type of biometric recognition is commonly used in industry, where working conditions are unclean or harsh. Features such as the length of fingers and width of the hand are used to identify an individual, and although hand geometry is not as unique as fingerprints, this type of biometric system is a popular choice for time and attendance software in some industries.Hand scanners work by taking a picture of a hand after it is placed on a flat surface, with fingers aligned correctly. The resolution of each scanner determines the detail picked up, with 100dpi being low resolution and 400 dpi, high resolution. This type of biometric device is commonly used for identity verification, and is popular for time and attendance purposes.
