The system includes a wholesale server which issues electronic data such as an electronic ticket, an agent server which performs selling processing of the electronic data, and a client terminal which acquires the electronic ticket and the like by communicating with the wholesale server and the agent server. The agent server attaches to an electronic data delivery request for electronic data such as a ticket from the client terminal, a token for an access to the wholesale server or another agent server positioned directly above the agent server, and transmits the request back to the client terminal. The client terminal transmits the electronic data delivery request with the token received from the agent server to the wholesale server. Thereafter, the wholesale server issues electronic data such as an electronic ticket in response to the electronic data delivery request with the token.
