This solution enables the automation of a public or private parking lot where access to the parking area is controlled by a vehicle barrier. The opening of the barrier is authorised following validation of a single or multiple access card or the emission of a paper entrance ticket. In the case of solutions with paid tickets, the client, before reaching the exit, must pay at the manual counter (manned by an operator) or at the automatic counter. The system is fitted with a “web/app” communication system for the manager to provide clients with information regarding available slots using a Mobile App.
