ABOUT THE FEATURES: 
 
Fingerprints: The U300 features an advanced ergonomic fingerprint reader. Capable of storing up to 50 fingerprints, allowing users to unlock the door directly from the handle. This convenient design ensures quick, seamless access without the need for additional steps. False Acceptance Rate is less than 0.0001%.
 
Password: The password is the most convenient way to share access with your guests. You can create different types of password access: Custom Passwords, Limited-Time Passwords, One-Time Passwords, and Dynamic Passwords.
 
Smart Automation with Aqara and Third-Party Devices:  When paired with an Aqara Thread-enabled Matter Hub (such as the M3), the U300 supports smart home automation and remote unlocking. Thanks to the Matter-over-Thread protocol, it is also compatible with third-party ecosystems, including Google Home, Alexa, IFTTT, and Samsung SmartThings. This flexibility enables seamless integration into various smart home setups, enhancing automation and convenience. (After adding the door lock to the Aqara Home app, only the administrator's fingerprint or password can reset the door lock.)
 
Multiple Protections: It has a multi-layered protection system. You will receive an alarm if multiple false entry attempts are detected. Additionally, there are features such as a low battery alarm, built-in doorbell, wrong password alarm, abnormal activity alarm, anti-prying alarm, and visual intercom.
 
Door Thickness Range: Supports door thicknesses from 45mm to 100mm. Different-length shafts are included in the package.
 
Physical Key: An emergency backup is always available with the metal key, to be used in case of battery failure or drain.
 
USB-C Port: For emergency recovery in case of battery drain, you can use a power bank to power the lock and unlock it using your fingerprint.
