Understanding Biometric Time Clocks

Biometrics is the practice of automatically identifying people by one or more physical characteristics. The use of biometrics in time and attendance systems makes it much more difficult for one employee to clock in or out on behalf of another (i.e. "buddy punching"). In most cases, hand geometry time attendance systems will have a lower false reject rate than fingerprint systems.

Biometric time and attendance systems are devices that use human body parts, mostly palms or fingers, as an identification mark for every employee. They come in fingerprint and hand geometry models. Biometric time clock devices comprise a scanning device, software to convert scanned information into digital format, and a database to store the data.



Hand Geometry or Handpunch models, uses software and an employee database to match a three-dimentional image of the hand to the stored image. If both images match, then access is granted or the time is recorded.

Fingerprint Biometric Time Clocks use human fingerprints as an identification mark. As it is almost impossible to forge or tamper fingerprints, these systems are the most secure. Fingerprint biometric readers are generally lower cost and are often used for entry-level systems

Biometric time and attendance systems eliminate proxy or buddy punching problems. Most of these systems are capable of storing the attendance data and printing various kinds of reports. As the data is stored in the database, these systems can be directly connected to payroll software.
