Smart Door Locks

A smart door lock is an electronic lock that offers multiple ways to unlock a door beyond a physical key: fingerprint for instant biometric access, facial recognition via a built-in camera, a password/PIN keypad supporting multiple user codes, RFID/NFC card or fob tapping, app control for remote unlocking and access management, and a mechanical key as an emergency backup — giving redundancy so that if one method fails, another still works.
