An information code reading system includes an information code terminal and a server communicably connected to the terminal. In the terminal, an information code with first and second information is imaged, and transmitted to the server information indicating the information code. The server decodes the information indicating the information code received from the terminal, and memorize information showing that the information code has become an object being read, when the second information is provided via the decoding process. From the server, either the first information or information related to the first information provided via the decoding process is transmitted to the terminal. Hence, in the terminal, a process is performed with the first information received from the server.
