 # ASSA ABLOY Visionline Access Control System
 
+## Overview
+
+Seam integrates seamlessly with the [ASSA ABLOY Visionline Access Control System](https://www.assaabloyglobalsolutions.com/en/hospitality-solutions/access-management-systems-for-hotels#gw-group-text-and-media-14987d7731) (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.
+
+***
+
+## Supported Devices
+
+This integration supports all readers and wireless locks connected to the Visionline ACS.
