Nuki provides retrofit smart access solutions (Smart Lock, Keypad, Door Sensor, Opener and more) that enable keyless entry and digital key management—useful for hospitality operators who want to automate guest access without exchanging physical keys. Access can be granted via the Nuki app, keypad code, fingerprint (Keypad 2), fob, smartwatch, or traditional key fallback, with an activity log that records door events for transparency.

For short-term rentals and serviced apartments, Nuki is commonly used to automate self check-in by issuing time-restricted access permissions per reservation and revoking them automatically after checkout. Nuki supports remote access (via built-in Wi‑Fi on newer locks or via Nuki Bridge on some setups) and integrates with major smart home ecosystems using standards like Matter over Thread, helping operators standardize access across properties while maintaining strong privacy and security practices (designed in Austria, made in Europe).
