A biometric device is a security identification and authentication device. Such devices use automated methods of verifying or recognising the identity of a living person based on a physiological or behavioural characteristic. These features include fingerprints, facial images, iris prints and voice recognition.

Automated time and attendance systems, such as ClockedIn, can use electronic tags, bar code cards, magnetic stripe cards, bio-metrics (vein reader, hand geometry, fingerprint or facial) and touch screens instead of Role that employees touch or slide to identify themselves and record their work hours when entering or leaving the work area. The recorded information is then ideally transferred automatically to a computer for processing, although some systems require an operator to physically transfer data from the synchronisation point to the computer using a portable memory device. You can then use the computer to perform all calculations necessary to generate employee time sheets that are used to calculate employees' salaries. An automated system reduces the risk of common errors in a manual system and allows the workforce to be more productive rather than wasting time on tedious administrative tasks. Time attendance devices using Cosas Internet technology are revolutionising industries like 'SmartBarrel' with the construction industry by introducing an advanced time clock device that not only controls time and automates payroll but also Analyses the data collected live and behaves accordingly.
