1. A mobile communication device, operable to perform data verification processing when the mobile communication device drives an internal smart chip to perform transactions with a front end access device, the mobile communication device comprising:

  • a first receiving slot storing a subscriber identity module (SIM);

    a second receiving slot storing a smart chip storing identity (ID) verification information, wherein both the first and second slots electrically connect both the SIM and smart chip to a processing unit;

    wherein when the smart chip receives a transaction request, the smart chip executes a transaction procedure according to the ID verification information and the smart chip sends a processing result of the transaction procedure to the processing unit;

    an external antenna located external to both the SIM and smartchip and within the mobile device and electrically connected to the smart chip; and

    at least one extended contact external to the second receiving slot and electrically connected to the second receiving slot, the extended contact connecting the external antenna with the smart chip;

    the external antenna further comprisinga radiating part comprising at least one antenna coil operable for radio communication of the device;

    a feeding part electrically contacting the at least one extended contact; and

    a conducting part, connecting the radiating part and the feeding part;

    wherein the extended antenna, when installed under a battery of the mobile device overlaying the feeding part, conducting part, SIM, and extended contact, electrically connects the feeding part and extended contact; and

    wherein the conducting part is flexible such that after the installation of the extended antenna, the conducting part flexes enabling the radiating part to overlay at least a portion of the battery, conducting part, feeding part, and extended contact.
