How to allow requests and data, which are relevant to a service using an IC (Integrated Circuit), to be exchanged among a SAM unit serving as a data-processing apparatus, a server and the integrated circuit with a high degree of efficiency in an operation to render the service. The server transmits a first command requesting an IC module (the integrated circuit cited above) of a portable communication apparatus to carry out processing to the SAM unit. The SAM unit interprets the first command and transmits a second command for operating the IC module in accordance with a result of interpretation of the first command to the IC module by way of the server. The IC module carries out the processing in accordance with the second command and transmits a first response containing a result of the processing to the SAM unit by way of the server. If an outcome of the judgment formed on basis of the first response indicates that the above processing has been completed, the SAM unit transmits a second response indicating completion of the processing to the server.
