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

The Evolution of Fingerprint Scanning TechnologyHistorical Background of Fingerprint ScanningFingerprint identification has been used for centuries as a reliable method of establishing personal identity. From ancient Babylon to 19th-century Europe, the uniqueness and permanence of fingerprints have

A capacitive fingerprint scanner is a biometric device that uses capacitive sensor technology to identify and verify fingerprint information. Compared with traditional optical fingerprint scanners, capacitive fingerprint scanners have many advantages, making them a more ideal choice.Capacitive finge

What is the principle of fingerprint module? Fingerprint identification module technology principle introduction. Fingerprint, due to its lifelong invariance, uniqueness and convenience, has become almost synonymous with biometric identification. Fingerprints are lines on the skin at the end of a pe

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
