Advantages and disadvantages of capacitive fingerprint scanner and optical fingerprint sensor:The fingerprint is composed of ridge line and valley line. Ridge line is the raised part of fingerprint texture, and valley line is the concave part of fingerprint texture.The optical fingerprint sensor is

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.

A Chinese technology company has successfully developed a new optical fingerprint sensor. The sensor uses the latest infrared imaging technology to quickly and accurately identify human fingerprints. At the same time, the sensor also has anti-counterfeiting function, which can effectively prevent the fingerprint from being copied or tampered with.
