Door Smart Lock Fingerprint Padlock

 

This Black Silver USB Rechargeable Door Smart Lock Fingerprint Padlock features quick unlocking with high-precision fingerprint recognition and durable zinc alloy construction for enhanced security. Common issues with fingerprint recognition often stem from finger wear, dirt, moisture, or a smudged sensor—ensuring both finger and sensor are clean and dry improves accuracy. The lock supports up to 10 fingerprint registrations; registering at least three fingerprints is recommended to avoid access problems due to finger damage. When the battery is low, a red light flashes, and the lock can be charged via Micro USB while in use. A full charge offers up to 12 months of standby time. If no fingerprints are registered, the lock opens with any fingerprint; otherwise, only registered prints grant access.
