The Wireless Calling System for Customers, also known as Paging System, finds its application in self-service restaurants or foodcourts, i.e. places where guests pick up their orders themselves. When an order is ready for collection, the customer pager transmits a light signal and/or vibration. It can be freely programmed to be compatible with transmitters from our offer, especially buttons and keyboards that transmit many messages at the same time. It has a modern design, and each pager can have a personalized graphic design with a logo on request.
