With the development of urbanization, the phenomenon of queuing in the supermarket is becoming more than before. This will not only waste time, but also increase the workload of the supermarket to maintain order. This can‘t give customers a good shopping experience.
We design a set of automatic payment system. Customers put the goods on the conveyor belt, the machine can automatically scan the commodity bar code, and then, product price is displayed on the screen. Customers complete the payment operation by themselves. This greatly reduces the customer's queuing time and the human cost of the supermarket.
