FAP30 USB Fingerprint Scanner for Identification Solution

As for capacitive fingerprint recognition technology in fingerprint scanners, in simple terms, when the pressure sensor senses the pressure, it will use the capacitor to scan the fingerprint, identify the fingerprint using the potential difference generated by the tiny concave and convex drop of the finger belly texture, and then form the fingerprint gray image, and then compare and match with the fingerprint database data recorded in advance to complete the identification, The thermal sensor...
