Abstract
A portable terminal obtains a first code used to obtain provision information and a second code, different from the first code, from a communication device. The portable terminal transmits the first and second codes to an information processing device, receives the provision information from the information processing device as a response to the transmission, and outputs the received provision information. The information processing device includes a first storage unit storing the first code and a second storage unit storing, by associating, the second code and the provision information. The information processing device receives the first and second codes from the portable terminal, obtains provision information associated with the received second code from the second storage unit when the received first code is stored in the first storage unit, and transmits the obtained provision information to the portable terminal. The first code is deleted in exiting from a specific area.
