Fingerprint sensor module technology principle introduction. Fingerprint, because of its lifelong invariance, uniqueness and convenience, has almost become a synonym for biometric identification. Fingerprints refer to the ridges and ridges on the front skin of a person's fingers. The lines are arranged regularly to form different patterns. This is the basis of fingerprint recognition.

The advantages of the optical fingerprint sensor module are mainly strong anti-static ability, good system stability, long service life, particularly high sensitivity, and can provide high-resolution fingerprint images, and the technology is also the most mature.
