Customers can scan the QR code provided by the restaurant with their mobile phones, then access the online menu and ordering system of the restaurant, choose among different dishes, set meals and drinks, and submit the order to the restaurant.

This way can facilitate customers to order food quickly and accurately without the intervention of waiters, and can avoid problems such as language communication barriers and wrong ordering in traditional ordering methods, and at the same time improve customers' dining efficiency and reduce the work of service personnel.
