A service registration system includes a server that provides a service through a network, a peripheral device capable of communicating with the server and using the service, and a terminal device capable of communicating with the server and the peripheral device. When the terminal device receives the registration requesting information representing information related to registration necessary for using the service from a user, the terminal device transmits registration requesting information to the server. When the server receives the registration requesting information from the terminal device, the server transmits service information necessary for using the service. Further, the terminal device can transmit the service information to the peripheral device when it receives the service information from the server. Further, when the peripheral device receives the service information from the terminal device, the peripheral device stores the received service information and operates in a mode where the service is usable.
