Abstract
An entry control system (ECS) allows the movement of authorized personnel and material through normal routes while detecting and delaying movement of unauthorized personnel and contraband. This paper presents an overview of several unique design and operating principles used in the implementation of a positive identity entry control system utilizing proximity cards. The system design incorporates distributed processing to .support geographically separated entry points and redundancy such that no single point failure will shut down operations. The functionality and integration of the photo identification system, the visitor authorization system, and the access control and contraband detection system will be discu.ssed. System unique features such as temporary badge issue for lost or forgotten badges at entry points using video lookup, visitor processing, and ergonomic and environmental considerations for the design of the proximity card based entry lane will be covered.
