Dish ordering method based on two-dimensional code and system thereof, mobile terminal and server side

The invention is suitable for the technical field of information, and provides a dish ordering method based on a two-dimensional code and a system thereof, a mobile terminal and a server side. The method comprises the steps that the two-dimensional code is generated according to network access information, dining table identifier information, a system login name and a system login password, and the system login password is periodically updated; the mobile terminal scans the a two-dimensional code and analyzes the a two-dimensional code so as to obtain the network access information, the dining table identifier information, the system login name and the system login password; the mobile terminal is accessed to the network according to the network access information; the mobile terminal logs in the dish ordering system according to the system login name and the system login password; the mobile terminal uploads the dining table identifier information to the server side of the dish ordering system; and the server side provides a corresponding menu to the mobile terminal according to the dining table identifier information so that a mobile terminal user is enabled to perform dish ordering operation in the menu. According to the dish ordering method based on the two-dimensional code and the system thereof, the mobile terminal and the server side, the two-dimensional code dynamically changes so that security of the dish ordering system can be ensured and malicious dish ordering can be avoided.
