Abstract: An information processing terminal defines a data transfer state for permitting a contactless data communication through an IC card and a data not transfer state for not permitting the contactless data communication so that the IC card manages the communication state of the information processing terminal. The IC card can transfer data to the terminal side depending on whether it is in any of the data transfer state and the data not transfer state without depending on the notification from the information processing terminal, synchronization can be easily established, a transfer speed can be increased, and a large amount of data can be transmitted.

Abstract: An IC card compatible with a DES scheme and an AES scheme having a security strength different from that of the DES scheme, includes an inhibition information receiving section for receiving inhibition information for inhibiting predetermined manipulation from being performed in a storage region of the IC card using the DES scheme from an issuing device using the AES scheme, an inhibition flag setting section for performing inhibition processing for inhibiting the predetermined manipulation by the inhibition information, a manipulation request receiving section for receiving a manipulation request from a service providing device or the issuing device, and a manipulation executing section for executing the requested manipulation if the requested manipulation does not correspond to the predetermined manipulation inhibited by the inhibition information.

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.
