A: The YRHAND M1BL biometric smart lock stores up to 100 fingerprints and up to 200 IC cards. Keypad passcode user capacity is unlimited, making it ideal for households, rental properties, offices, and shared spaces with many users.
Q: Is this smart lock weatherproof enough for an outdoor front door?
A: Absolutely. This lock carries an IP66 weatherproof rating, meaning it is fully protected against powerful water jets and heavy dust ingress.
