Answer:
Slave readers are commonly used in various access control scenarios, including:
Multiple entry points: Slave readers allow for access control at additional entry points such as secondary doors, gates, or turnstiles, supplementing the main entrance controlled by the master reader.
Remote locations: Slave readers are often utilized in remote or distant areas of a building or facility where a direct connection to the master reader may not be feasible.
Separate zones or areas: Slave readers can be deployed to secure specific zones or areas within a building, providing access control tailored to individual security requirements.
High traffic areas: Slave readers can be installed in areas with high foot traffic to distribute the access control workload and prevent congestion at a single entry point.
