Point of sales terminal, point of sales system, and method for managing cash-on-hand information

摘要

Cash received from a customer is placed by cashier into a change device, which is connected to a point of sales terminal. The change device counts an amount of cash by its type, and stores a counted amount into a memory unit. Further the change device stores an amount of change that discharged from the change device. The amount of cash stored in the memory unit is sent to the point of sales terminal and to a server. The server contains cash-on-hand table, and by receiving the amount of cash from the point of sales terminal, the server updates the cash-on-hand table. The cash-on-hand table is used to determine whether any of the point of sales terminal needs cash to be supplemented or not.
