The operation of the Ordercube is simple. The customer who wants to order or pay only has to press SERVICE or PAY, and the Ordercube will immediately change color. It will continue to change gradually, for example, from blue to dark pink, to inform the servers which customer has been waiting longer. Furthermore, the true magic of the solution occurs through the sending of a notification directly to the Ordercube smartwatches, on which each server will have selected their own tables.
