Types of fingerprint locks
1. Optical fingerprint lock: Optical fingerprint lock uses optical principles to collect fingerprint information. Its advantage is that the price is relatively low and suitable for most home users. However, the optical fingerprint lock has poor recognition effect on dry fingers or severely worn fingers.
2. Capacitive fingerprint lock: Capacitive fingerprint lock uses the capacitive principle to collect fingerprint information. Its advantage is that it has high recognition accuracy and is suitable for various finger conditions. However, the price of capacitive fingerprint locks is relatively high and is suitable for high-end users.
3. Ultrasonic fingerprint lock: Ultrasonic fingerprint lock uses the principle of ultrasonic waves to collect fingerprint information. Its advantage is that the recognition accuracy is very high and it is suitable for all types of finger conditions. In addition, the ultrasonic fingerprint lock can also detect the blood flow of the finger, thereby identifying fake fingers and preventing them from being copied. However, the price of ultrasonic fingerprint locks is relatively high and is suitable for high-end users.
