A spatial light transmitter of a content supplying system stores ID information of its own and emits spatial light on which the ID information is superimposed from a light emitting portion. A spatial light receiver is used by being connected to a handheld terminal and receives spatial light emitted from the spatial light transmitter. When a user carries the handheld terminal and moves close to the spatial light transmitter, the spatial light receiver receives spatial light emitted from the spatial light transmitter, and ID information obtaining means of the spatial light receiver obtains the ID information which is superimposed on spatial light from a light receiving signal of the light receiving portion, thereby outputting the ID information to the handheld terminal. Alternatively, the ID information obtaining means of the handheld terminal obtains the ID information on the basis of the light receiving signal, and the handheld terminal reproduces the content selected on the basis of the ID information.
