Many restaurants use the ordering system of WeChat, Alipay, Meituan, and Delivery Bao, etc., mainly for the following reasons:

Improve dining efficiency: code scanning ordering can greatly shorten the time of customer ordering, and improve the efficiency of dining. Customers can scan the QR code to browse the menu, select dishes, place an order and pay directly on their cell phones, without waiting for the service of waiters, which saves customers' time.

Reducing labor costs: scanning code ordering can reduce the number of waiters, thus reducing labor costs. The main work of the waiters can be changed to provide more detailed service to customers and improve their dining experience.

Improve service level: Code ordering can improve the efficiency and accuracy of the service, and reduce the errors and mistakes due to verbal communication and human factors. At the same time, the code ordering system can provide some additional services, such as recommended dishes and favorable activities, to improve customer satisfaction and loyalty.

Maintaining hygiene and safety: During the epidemic, code ordering can reduce the contact between people, maintain a certain social distance, reduce the risk of infectious diseases, and ensure the hygiene and safety of customers.

Therefore, code ordering has become an ordering method adopted by more and more restaurants, which can improve the dining efficiency and service level of the restaurant, and at the same time reduce the labor cost, in line with the modern consumers' demand for fast and convenient and hygiene and safety.

But most restaurants still retain waiter ordering as a supplement to meet the different needs of customers
