Fuente: WIPO Food Portada According to the present invention, a food ordering and paying method using a kiosk for ordering food uses an order interface screen which allows a user to personally order food through a kiosk for ordering food or is selectively displayed on a user terminal through a QR code to select a food menu to allow a plurality of users to conveniently use a limited number of kiosks for ordering food, and selects a menu to be ordered through the order interface screen displayed on the user terminal instead of selecting food to be personally ordered through a kiosk for ordering food to generate a payment code and scan only the payment code by the kiosk for ordering food to order and pay for food. If a plurality of users wait at a kiosk for ordering food to order food, food is selected during waiting time to generate a payment code and use the generated payment code to order and pay for food to reduce the time spent in ordering food at the kiosk for ordering food.
