An Assistant Service for Customers in QR-payment with the Merchant Presented Mode

A QR payment assistant service in Merchant presented mode is proposed. The service could improve consumer's payment convenience and help the big data analysis of the payment data and goods supply chain. In this paper, we show the prototype design and implementation of the ordering system. The front-end Ajax helps customers to select the desired category/menu from the main menu, and the total price is calculated automatically.
