A memory card mounted in a general purpose ATA expansion memory location in a separate electronic device, such as a high-class digital camera, includes a data communication feature for transmitting the memory contents to a mobile station. Expansion cards containing memory which can be written and read are called Compact Flash, in accordance with the Flash EEPROM memory contained in small-sized cards. The data communication is performed on a short-range, low power radio frequency (LPRF) link. The memory card is also applicable for instance in a personal digital PDA notebook, where the input data can be stored in an expansion memory. The duplex feature of the expansion memory enables the data to be transmitted at a radio frequency to a mobile station. The data communication features of the wireless device are available for forwarding the data.
