This Biometric Door Lock is as smart as it is elegant, providing your room with an added level of safety and security without announcing it to the world. With a soft unlocking motion, it is ideal for inner doors of residential, apartment, or other private spaces.
Features:
- Two modes of unlocking the Biometric Door Lock: Using your fingerprint and an emergency key. After registering your fingerprint, the biometrics technology with a 98% recognition rate allows you to never carry the key when you go out. The two mechanical keys just work as an emergency unlock method.
