The main purpose of the restaurant to scan and order food through WeChat Alipay and Chuanbao for free is to improve the efficiency of ordering food and reduce the service time. By scanning the QR code or using the ordering system, customers can browse the menu and order food directly on their mobile phones without waiting for the waiter to ask about ordering food. This not only saves the waiting time of customers, but also reduces the work pressure of waiters and improves the service efficiency.

In addition, scan sorting has the following advantages:

High accuracy: when customers order food on their mobile phones, they can avoid the wrong ordering caused by unclear language communication or misunderstanding of waiters, which improves the accuracy of ordering food.

Provide more information: The ordering system can provide more food information, pictures and evaluations to help customers make better ordering decisions.

Data analysis: The ordering system can record each customer's ordering preferences and historical orders, and provide data analysis and operational decision-making basis for restaurants.

Therefore, using scanning ordering technology in restaurants can improve service efficiency and accuracy, reduce costs and enhance customer experience.
