HARFO Fingerprint Smart Door Lock – Front Door, App Control, Keyless Entry

Overview

Upgrade your entry with the HARFO Fingerprint Smart Door Lock, a flexible, high-tech solution for modern homes. This all‑in‑one lock blends biometric access with digital controls, offering multiple ways to unlock and manage who can enter. You can use fingerprints, the HARFO app, numeric passcodes, IC cards, a physical key, or an e-key option for external compatibility. The lock stores up to 50 fingerprints, 250 passcodes, and 1000 IC cards (3 included), making it suitable for households, guests, and short-term rentals. Its black finish and handle set deliver a contemporary look, while the hardware is designed for standard wooden doors 35–50 mm thick. Left or right opening is supported, and installation is designed to be straightforward for a wide range of doors.

Beyond a sleek appearance, this device is built for real life. It combines convenience with practical security features that adapt to your routine, whether you’re at home, hosting visitors, or managing a property from afar.
