Fingerprint lock
Fingerprint recognition technology usually uses the overall characteristics of fingerprints, such as grain shape, triangulation points, etc., to classify, and then uses local features such as location and direction to identify users. It scans fingerprints quickly, but fingerprints are easy to copy. It is more suitable for the use of company doors or high-end residential areas.
Iris lock
The accuracy of iris feature matching exceeds that of DNA matching, and this technology has been widely regarded in the biometric industry as the most accurate, stable, and upgradeable identity recognition system at present, but it is expensive. Therefore, it is suitable for government agencies, military bases, banks, high-end apartments, etc.
Voice-activated lock
Sound can be used to unlock, but the environmental noise interferes with recognition, resulting in the voiceprint feature is not easy to extract, and the voiceprint unlocking needs to turn on the microphone all the time, which consumes a lot of power, which is more suitable for new Internet companies or industries.
Palmprint locks
I learned that the palm print lock only needs to raise the palm of the hand and scan it against the framing lens to open the door lock. However, the detection surface of palm print unlocking is larger, and it is easy to be unevenly stressed on the palm surface, so the convenience is not enough, and it is more suitable for home doors.
Face recognition lock
The advantage of face recognition lock is that the recognition object must be present at the recognition site, and it is difficult for others to imitate, but facial recognition is affected by many factors such as lighting conditions, facial coverings, age, etc., and is more suitable for use in public places, such as automatic ticket inspection of train tickets.
