An information processing system includes an information acquiring apparatus for acquiring data and a server, and executes multiple processes defined in workflow information. The workflow information defines order of the multiple processes. Either the information acquiring apparatus or the server performs the multiple processes defined in the workflow information. When a specific process is included in the multiple processes defined in the workflow information, the information acquiring apparatus transmits target data to the server before the specific process. The server receives the target data, and performs the specific process out of the multiple processes defined in the workflow information.
