Ordering menu generating system and method based on dynamic two-dimension code entrance

The invention discloses an ordering menu generating system and method based on a dynamic two-dimension code entrance. The method includes: step A, starting an ordering application of a client side, and connecting a printer well; step B, using a founding function of the ordering application, and printing a unique two-dimension code receipt for a customer; step C, using WeChat to scan two-dimension code on the receipt by the customer, and jumping to an ordering service platform of a cloud server if scanning is successful; step D, selecting menu and confirming an order by the customer in a self-service manner; step E, after ordering is successful, sending a pushing message to the client side by the service platform, and printing a menu receipt. According to the ordering menu generating system and method, for each visiting customer, the ordering application named 'WeChat Food Takeout' needs to be started to print the unique and non-repeated two-dimension code as an online entrance. After each customer pays for the corresponding order, the two-dimension code becomes invalid, in this way, the technical problem of conventional WeChat ordering is solved.
