The Technology Of Biometric Employee Punch Clocks
Biometric technology is relatively new, especially in the workforce. However, because of time theft and payroll losses more employers are implementing the use of a biometric employee punch clock. The most common type of biometric employee punch clock is the fingerprint clock. This type of clock uses fingerprint recognition technology to clock employees in and out of the work place. This technology uses the ridges and patterns in a person's fingerprint to identify them. The ridges are the high points in the pattern and both of these are unique to an individual.
This biometric technology has long been used as a means of identification in law enforcement. The reader takes the image of the print and matches it to a stored print by comparing specific points in the print. An employee simply places their fingerprint in the biometric fingerprint reader and the machine clocks them in or out. This technology can save a lot of paperwork for the employer. Records kept using a biometric employee punch clock are more accurate than manual records.
The clocks are easy to use once set up. However, setting up these systems can be quite time consuming. Some systems have had problems in the past with dropping prints from their memory. Some worry about identity theft but because the clocks do not measure all of the print pattern then a thief could not recreate a fingerprint pattern from one stored in the memory of the clock. The use of fingerprint recognition technology is the most common for biometric employee punch clocks.
While the biometric employee punch clocks that measure fingerprints are most common, there is another alternative for employers. There are clocks that measure hand geometry. Hand geometry recognition has actually been in use longer than fingerprint recognition. However, as fingerprint recognition becomes more popular and is more accurate at identifying an individual fewer of these clocks are sold. These clocks are limited to verification and not identification because the characteristics are not necessarily unique to each individual like a fingerprint. These time clocks analyze the length, height, thickness, and width of an individual's hand. Due to some environmental or logistical concerns, the biometric employee punch clock using hand geometry recognition is the best solution for an employer. Workplaces that are outside or construction and landscaping sites in which employees tend to damage their hands may be better off with a hand geometry reader. Clocking in with a fingerprint reader might be difficult under these circumstances.
Either of these technologies (biometric employee punch clock and hand geometry recognition) make payroll and employee records much easier to handle for the employer.
