• 【3-in-1 Unlocking System】No more worrying about lost or forgotten keys. Your fingerprint is always with you and cannot be duplicated without permission. This smart door knob supports fingerprint (up to 50 users), passcodes (up to 100 users), and 2 backup keys for secure and flexible access.
• 【Privacy-Focused Design】All fingerprint and app data are stored locally only, with no cloud upload. When paired with the Tuya Gateway (ASIN: B0DBVDSG9M), you can enable remote control and unlocking via smartphone. Ideal for homes, apartments, offices, bedrooms, and garages.
