## Overview

Seam integrates seamlessly with the ASSA ABLOY Visionline Access Control System (ACS), a widely-used on-premises access control platform for hotels. This system supports doors, elevators, turnstiles, and gates, enabling you to secure either a single building or multiple buildings using the same setup. Visionline uses a data-on-card platform, significantly reducing installation costs because the locks can function offline. Additionally, the capability of the system to operate independently of network connectivity enhances the reliability and flexibility.
