A Smart Door combines electronic sensing, authentication, and mechanical components to manage access efficiently. Multi-modal authentication allows flexibility for users while supporting structured security practices.

UWB enables doors to detect proximity and approach direction, while NFC confirms intentional user interaction. Biometric sensors verify identity directly, and PIN codes or mechanical keys remain available for compatibility.

These systems can operate locally without constant network connectivity, supporting reliability. Installation options allow smart doors to be integrated into new projects or retrofitted into existing buildings.

Through layered design and flexible installation, Smart Door systems support adaptable access management across various use cases.
