They are then converted into a greyscale image. Thermal scanners, such as the CSD201, operate by sensing the tiny thermal differences between the ridges and the valleys in the fingerprints.
There are two main types of finger scanners, optical and capacitive, with new technologies such as thermal sensors. This feature saves valuable time and ensures users give quality prints each time without a supervising party.Ī fingerprint scanner can be defined as a biometric security device that identifies and authenticates an individual’s fingerprint to identify them. LEDs on the user interface facilitates the acquisition procedure by indicating the fingerprint(s) have been acquired and providing feedback on the quality of the prints.

This information is then transferred to custom-built software and checked against pre-existing data to identify an individual. The image is captured by a state-of-the-art sensor that converts the ridges and valleys of the print into digital data, creating an individual’s personal fingerprint code. When an individual places their finger(s) on the scanner’s glass panel, the Cogent Fingerprint Scanner shoots a bright light onto a glass prism under the panel, which bounces off the panel and onto a lens to capture an image of the print.Ĭogent’s advanced optical system fully reduces the impact of ambient light and direct sunlight while permitting the capture of fingerprints from marked, stained or dark fingers.
Cogent Fingerprint Scanners are optical devices designed to capture the unique qualities of a person’s fingerprint.
