Optical fingerprint sensor mainly uses the principle of light refraction and reflection to collect fingerprint images. Put the finger on the optical lens, under the irradiation of the built-in light source, the light is shot from the bottom to the prism, and is emitted through the prism, and the Ang

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

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.
