Abstract
A data communication system includes an IC card function execution unit, a card reading/writing device, and an information processing terminal. The IC card function execution unit has a controller that causes the card reading/writing device to execute a data transfer operation to a memory in the IC card function execution unit through a contactless interface or causes the information processing terminal to execute a data transfer operation to the memory through a wired interface. The controller executes a data transfer between the card reading/writing device and the information processing terminal on a communication path composed of the contactless interface and the wired interface through the IC card function execution unit interposed therebetween. When the IC card function execution unit receives data from the information processing terminal through the wired interface, the IC card function execution unit directly transmits the data to the card reading/writing device through the contactless interface.
