Multi-interface wireless storage device

A multi-interface wireless storage device for a portable imaging apparatus with an opened slot is disclosed, which has a wireless data transmission card and a wireless data storage unit. An adapter card in the wireless data transmission card can provide different memory card interface in coincidence with corresponding adapter slots and further couple pin information of the memory card interface to corresponding adapter slot. Next, a re-configurable interface control module sets the adapter cable as an interface of the corresponding pin information to receive image data transmitted by the portable imaging apparatus and further transmit the image data to a second wireless module of the wireless data storage unit via a first wireless module. Finally, an access control module writes the image data to a storage medium.
