Abstract:
PURPOSE: A control method of a real-time seat reservation system using QR code recognition is provided to recognize a QR code which is printed on an advertisement using a mobile terminal, thereby enabling seat reservation in a real-time seat reservation system. CONSTITUTION: A control unit receives a QR code image photographed by a camera module (S10). The input QR code is data-converted, classified into multiple menus, and displayed on a display unit (S20). The control unit receives menus input through a key input unit (S30). Depending on the received menu, data included in the QR code are displayed (S65). If the menu is for seat reservation, a seat reservation server is accessed (S410, S420). According to the procedure provided by the seat reservation server, seat reservation is performed. Upon a payment request, the authentication information stored in a USIM card is sent to the seat reservation server (S450). After the payment is completed in the seat reservation server, a seat reservation ticket is stored (S460).
