The situation at the end of a queue is often confusing for customers. Normally it takes some time until the customer recognises an available counter. This time reduces your productivity and costs a lot of money.
A proactive system that guide customers to the next available counter or desk reduce the waiting time for your employees between two transactions. This idle time reduces the service quality and your productivity.
In one of the first Qmetrix projects a check-in queue was equipped with a monitor showing the next available counter. Additionally an acoustical signal was installed. The result was that the productivity of the whole check-in process increased by 20-25%.
