Fingerprint Clocking Terminals
More fingerprint clocking terminals are available on the market than any other type of biometric device. Virtually all readers are manufactured in the far east and they can vary considerably in cost and inevitably reliability. Not all fingerprint readers are equal and the price usually reflects the quality of the device that you’re purchasing.
Fingerprint readers are different from vein readers (which shine a light through the skin to view the vein patterns below the surface). Fingerprint clocking terminals look at the whorls, arcs and loops that make up a person’s unique fingerprint. All types of biometric clocking terminal will record just the key pieces of biometric information (such as the location of a whorl in relation to another recognisable element) and store these as a ‘template’ in the clocking terminal for comparison with future reads.
The reliability of a fingerprint reader is determined by the quality of the sensor and the superiority of the matching algorithm embedded in the terminal. Egress Systems primarily sell Suprema fingerprint terminals because they offer a range of sensors and a world class matching algorithm that performs consistently. Three sensor types are available from Suprema: capacitive, optical and thermal.
