Smart Fingerprint Padlock – Keyless Security for Bike, Gym, Luggage & More
Upgrade your security with this intelligent fingerprint padlock. Featuring a semiconductor biometric chip, AI-powered fingerprint recognition, and three flexible unlocking methods, this IP68-rated padlock is built for everyday use indoors and out. Made in Mainland China.
Three Ways to Unlock
- Fingerprint: Place your registered finger on the sensor — unlock in under 0.5 seconds with a false acceptance rate of just <0.001%.
- Mobile App: Use the companion app for remote unlocking, access history, permission management, and instant unlock notifications.
- USB Electronic Key: A physical backup option for when the battery is low or fingerprints can't be verified.
AI-Powered Biometric Recognition
The built-in 508 dpi semiconductor fingerprint chip uses AI algorithm learning to improve accuracy over time. It reliably reads dry, damp, or slightly worn fingertips with a false rejection rate of <1%. Store up to 20 unique fingerprints for shared access.
Smart App Control
Connect to the lock via the mobile app to view full unlock records, set user permissions, and add or delete fingerprints with a single tap. Real-time unlock alerts keep you aware of who's accessing your lock at all times.
Long-Lasting Rechargeable Battery
The built-in 120mAh lithium battery automatically enters sleep mode when idle to extend battery life. A full charge supports approximately 2,000 unlock cycles. When the battery is low, the indicator light flashes red four times after each unlock as a warning — simply recharge via the included Micro USB cable.
