To provide an information communication system capable of transmitting/receiving information by using a memory card.

A user registers personal information and identification(ID) information on the basis of a contract with an information management company (S30). The user selects required service information from a service menu (S90). Then, the user is allowed to input ID information (S110). User' s ID information recorded in the memory card is collated with the inputted ID information (S115), and when the contents of both the ID information coincide with each other, the coincidence is transmitted to an information management system 200 (S130). The system 200 transmits the personal information to the terminal of a service provider (S120). The service provider transmits the service information requested by the user to a user's information communication device.
