Abstract: A system for controlling access to a secure area under surveillance by a single ticket seller. A magnetically encoded ticket is sold by a ticket seller which is presented to a magnetic reader which verifies the ticket and allows passage through an electrically controlled turnstile. Verification of the ticket is automatically made and an electrical count, together with a mechanical count and a photocell count of all entries, is recorded. All detected information at a given location is recorded and controlled by a transaction terminal located on the premises. A remotely located central processing unit automatically and periodically communicates with each of a plurality of remotely located transaction terminals for causing all recorded information in each transaction terminal to be transmitted and recorded at a centrally located central processing unit.
