Abstract: An IC card includes a communication unit, a storage unit that stores a file, and a controller that interprets and executes a command instruction. The controller judges, when a command that instructs to select a dedicated file is input from an external apparatus, whether a certain fixed value is inserted at a predetermined position of the command, starts, when judged that the certain fixed value is inserted in a non-transaction state, transaction processing after accepting the command as a transaction start instruction simultaneous with the selection of the dedicated file, accepts, when judged that the certain fixed value is inserted during the transaction processing.

Abstract: According to one embodiment, a smart card includes a communication unit, recording unit, first reception processor, determination unit, and first transmission processor. The recording unit records data defined by definition information. The first reception processor receives a command from an external terminal. If the first reception processor receives the command, the determination unit determines whether or not data required for execution of the command is stored in the recording unit. If the determination unit determines that the required data is not stored in the recording unit, the first transmission processor transmits a response indicating the start of a session required to acquire data related to that data from the external terminal to the external terminal.

Abstract: According to one embodiment, a portable electronic device includes a communication section, a storage section, a processing section, and a first transmission section. The communication section transmits/receives data to/from an external device. The storage section stores therein an application configured to create a proactive command. When executing a command from the external device, the processing section creates a proactive command including information indicating the application by executing the application stored in the storage section. The first transmission section transmits the proactive command created by the processing section to the external device through the communication section.
