The difference between FPC semiconductor and semiconductor
Hello, dear, I'm glad to answer your question. FPC Semiconductor Company uses the principle of light reflection to reflect your fingerprints. The human fingerprint data is collected by the optical collection system and then converted into digital information for storage. When the finger touches the recognition area again, the system immediately starts the comparison system, and finally decides whether to pass the test by comparing the texture data between the two fingerprints before and after recognition. The biggest advantage of this identification method is its low price and simple comparison through optical principle. But the disadvantage is that the opponent is very sensitive to the degree of dryness and wetness. Dirty or wet hands can lead to recognition errors. Generally speaking, this technology is more common in card punching machines, fingerprint identification under the screen of mobile phones and fingerprint locks. Dense capacitance electrodes are added in the semiconductor fingerprint recognition area. So some people call this technology capacitance recognition and living fingerprint recognition. This identification technology is more accurate than optical fingerprint identification and can prevent false fingerprints from unlocking, but it is relatively expensive, so it is generally used in high-end products.
