An information acquisition system includes a communication terminal that reads an information code storing the point information and a service ID; and a server that stores point information and a service ID in association with each other, the communication terminal accessing the server and acquiring the point information from the server. The communication terminal extracts the point information and the service ID from the information code to transmit to the server the point information and the service ID. At a time of reception of the point information and the service ID, the server extracts, from the point information stored in the server, association point information corresponding to the point information that correlates with the service ID received from the communication terminal, and transmits the association point information to the communication terminal. The communication terminal outputs the point information, and the association point information received from the server.
