  • Patent number: 7083107
    Abstract: A memory card that makes it possible to select the service provided by changing an adapter instead of having selection switches on the outer appearance of the card. The memory card is capable of executing one of a plurality of applications that correspond to individual services and comprises: an adapter that designates one of the services; a main card body to which the adapter is removably connected; an interface for an external device; a memory unit that stores information of the plurality of applications; a detection unit that detects whether or not an adapter is connected to the main card body; and a CPU or LSI that executes the selected application based on the detection signal to provide the service to the external device.

  • Patent number: 6970066
    Abstract: A memory card reading/writing apparatus, access method, program and storage medium thereof, that have a psychological security function, or in other words a mild security function and that make it possible to perform various kinds of management of the memory card even when the memory card is lost. In the memory card reading/writing apparatus of this invention, an apparatus-user-information-acquisition unit acquires apparatus-user information from a memory unit that stores apparatus-user information that identifies the user of the memory card reading/writing apparatus. Also, a memory-card-user-information-acquisition unit acquires the main-memory-card-user information from the memory card that identifies the main user of the memory card. A user-information-comparison unit compares the two kinds of information, and outputs a comparison result. An output unit outputs specific output based on the comparison result.
