The present invention relates to a trading system comprising a trading device and a terminal device. The trading device accepts operations by an operator, and presents an operating screen displaying information relating to trading. The trading device is provided with an operating screen presentation unit capable of attaching to an object capable of being operated on, at least on the operating screen, an encoded image in which tag data for identifying content to be displayed on the terminal device have been encoded. The terminal device analyses an image captured by an image-capturing unit, and if it detects an encoded image, it displays a composite image in which an image of the content corresponding to the encoded image is superimposed on the captured image. |
