This system doesn’t use ticketing and is distinguished by its efficiency in queue management. Besides, it is based on a “first to come, first to be attended” logic. With one queue/ service for multiple counters, the single queue system is one of the simplest models for managing queues.
Whenever a service desk is free, the operator presses the call button, and the number of the service desk available for service is shown on the display. It’s a perfect solution for commercial stores, airports and pharmacies.
