ABSTRACT:
The present invention relates to a new improved modular structure to expand and enhance SIM (Subscriber Identity Module) card functionality, in which an expansion and enhancement module is fitted to a predetermined mobile communication device, and the predetermined mobile communication device comprises a subscriber identity module. The subscriber identity module is configured with an electrical connection module, and the electrical connection module is electrically connected with a controller, which can be an NFC (Near Field Communication) module. The controller is electrically connected with a subscriber identity chip and a Dual-interface card (Combi card), and the Dual-interface card is electrically connected with an antenna. Hence, according to the structure described above, the present invention is able to achieve contactless type transactions without the need to replace the SIM card or system operator.
