A terminal device acquires item property information from a medium, and transmits, to a server device, terminal identification information of the terminal device, which is assigned by the server device in advance and stored in storage means and item property information acquired from the medium. The server device stores the terminal identification information and the item property information received from the terminal device, and transmits, to a device, information generated based on the terminal identification information and the item property information received from the terminal device. The server device performs authentication of a user of the terminal device based on the terminal identification information. Because this terminal identification information is assigned by the server device, transmission of the information does not entail a risk of leakage of personal information, unlike a case in which personal information such as a telephone number is used for authentication. |
