A state notification apparatus comprises: a holding unit that, when one or more secure runtime environments and one or more non-secure runtime environments are selectively executed in a foreground, holds an identifier of a runtime environment that is being executed in the foreground; a determination unit that determines a state of the runtime environment executed in the foreground based on the identifier held by the holding unit; and a notification unit that causes a hardware device that cannot be accessed from the one or more non-secure runtime environments to notify the state determined by the determination unit.

To achieve backward compatibility for smaller chip cards, in particular to legacy card readers/writers or legacy mobile terminals, according to the present invention a smaller chip card comprises a card body and a first contact area () with dimensions and locations of contacts according to predefined standard. An integrated circuit chip () is, firstly, physically and electrically connected to contacts of a second contact area (), where the locations of contacts in the second contact area () are different from locations of contacts in the first contact area (). According to the present invention, the integrated circuit chip () is also connected to contacts in the first contact area ().

In a mobile communication system, the PAD of the data-processing-terminal-interface has a packet assembling/disassembling function for the protocol for data-link layer A and the protocol for data-link layer B. The protocol for data-link layer A of the data processing terminal prescribes that a frame, in which data transferred from the upper layer is inserted between flag sequences with a prescribed bit pattern, be transmitted usually, and that flag sequences without data transmission be transmitted when there is no data requiring transmission during communication. If flag sequences are transferred from the data processing terminal, the PAD deletes a part or all of the flag sequences and does not transfer them to the wireless communication unit. Consequently, a part or all of the flag sequences are not transmitted to the wireless communication channel. Therefore, power consumption by a wireless mobile station device or the like may be reduced, and the wireless channel may effectively used.
