A method for controlling a service device through a smart terminal based on near field communication (NFC) includes the steps of: activating NFC between the smart terminal and the service device; handing over the communication between the smart terminal and the service device to a secondary network through the NFC; executing, by the start terminal, a web contents execution program; providing, by the service device, control codes to the smart terminal; preparing, by the smart terminal, to utilize the control codes; displaying, by the smart terminal, a control/service screen of the service device on the web contents execution program by utilizing the control codes; detecting, by the web contents execution program, a user manipulation on the control/service screen; and transmitting, by the web contents execution program, a request defined in the control codes to the service device in response to the user manipulation.
