The system works as follows: after the customers enter the food court, order food and get a receipt, they are also handed a vibrating pager; when their order is ready, the headwaiter enters the order number into a transmitter and informs them – through vibrations of the pager, its LED lights and sound alerts that are suitable alternatives to traditional techniques – that they have to pick up the food at the counter. It should be noted that the use of this system not only prevents the formation of queues in front of the cash registers, but also results in customer satisfaction and relaxation.
