Description
An electronic device that records a digital image of the fingerprint pattern is known as a fingerprint reader. The captured image is known as a live scan which is then digitally processed. The distinguishing features are extracted and a fingerprint biometric template is created.
This biometric template is stored and will be used for matching later.
Optical scanners are the common types of fingerprint scanners that use an LED light to illuminate the finger.
The sensor detects and creates the fingerprint image by determining the light and dark areas created by the fingerprint ridges.
The scanning process starts when the individual places his finger on the glass plate that is known as a touch surface.
There are four types of fingerprint scanner: the optical scanner, the capacitance scanner, the ultrasonic scanner, and the thermal scanner. The basic function of these three types of scanners is to get an image of a person's fingerprint and find a match for this print in the database. The capacitance scanner is better because the images are more exact and precise. Scanners are used for scanning.
The fingerprint module has stable performance, perfect functions, and has multiple functions such as fingerprint collection, fingerprint registration, fingerprint comparison, and fingerprint search.
This module is controlled by the serial port. You can also use the computer serial port to control it as well. MSP430, 51, AVR, PIC, STM32, ARM, FPGA, Arduino controller can operate this module.
