Fingerprint recognition is a frequently used unlocking method for Fingerprint Scanner, with many people using it for attendance verification.
Its recognition speed and sensitivity directly impact user experience, making it crucial.
Currently, there are two main fingerprint recognition technologies: optical fingerprint recognition and semiconductor fingerprint recognition (biometric live fingerprint recognition).
Optical fingerprint recognition: This technology has been used for a long time, relying on fingerprint images for identification. Many company fingerprint attendance machines use this method.
However, it still has some problems, namely insufficient fingerprint recognition accuracy and the inability to distinguish between genuine and artificial fingerprints. It cannot recognize fingerprints with peeling skin, but it can recognize fingerprint molds!
Semiconductor fingerprint recognition: Some Capacitive Fingerprint Scanner brands have begun to market live fingerprint recognition technology based on capacitive sensing.
It primarily relies on capacitive sensing for identification, meaning it only recognizes fingerprints with temperature. The authentication speed is comparable to optical fingerprint recognition, and it also prevents fingerprint molds from being mistaken for the owner's fingers.
