Abstract

A Combi-SIM card framework of electronic purse combining wireless transceiver of mobile device is a framework that combines the mobile phone subscriber identity module (SIM or USIM) chip and the electronic purse smart card chip having no wireless induction analog circuit to form a complex subscriber identity module (hereinafter known as Combi-SIM) and further cooperates with a mobile device having multifunction wireless transceiver. Based on the fact that the multifunction wireless transceiver is equipped with the signal path selection functions, the mobile device not only works as a wireless card but also works as a card reader to read exterior wireless card or access the content of electronic purse smart card in the Combi-SIM. Herewith, it provides functions of electronic purse and telecommunication value added service integration. Consumer proceeds electronic purse transaction at anytime and anywhere through the convenience of carry-on mobile device.

Claims

1. A Combi-SIM card framework of electronic purse combining a wireless transceiver of a mobile device, wherein comprising:

a Combi-SIM card, the Combi-SIM card having a capacity to accommodate more than one chip and electronic wiring to provide signal connection for the interior chips and exterior system;

a SIM or USIM card chip, the SIM or USIM card chip being built into the Combi-SIM card and responsible for the function of mobile communication;

a smart card chip, the smart card chip being built into the Combi-SIM card and arranged in parallel with the SIM or USIM card chip, wherein the smart card chip does not have wireless induction analog circuit and works as electronic purse chip or Easy Card chip or other ATM card chip;

the wireless transceiver, with signal path selection function, being equipped with electronic wiring to transmit signal to the Combi-SIM card and disposed at a proper location of the mobile device substrate and controlled by the mobile device master controller to provide a plurality of signal path selections;

a RFID antenna, the RFID antenna being disposed at a proper location of the mobile device substrate and connecting with the wireless transceiver, wherein when the mobile device plays the role of card reader the RFID antenna works as an antenna of card reader and when the mobile device plays the role of a RFID tag, the RFID antenna works as an antenna for the RFID tag;

the mobile device, having a RF antenna and the wireless transceiver being disposed inside, and having a insertion slot for the Combi-SIM card, wherein the master controller of the mobile device substrate connects and controls the wireless transceiver.

2. The Combi-SIM card framework of electronic purse combining the wireless transceiver of the mobile device according to claim 1, wherein the smart card chip having no wireless induction analog circuit and the SIM or USIM card chip are built into the Combi-SIM card, wherein the smart card chip of electronic purse is not equipped with analog integrated circuit but utilizes the copper contacts C6, C4, C8 retained by the SIM card international specification to connect with the wireless transceiver of the mobile device, and such a connection interface is a low voltage digital logic signal interface.

3. The Combi-SIM card framework of electronic purse combining the wireless transceiver of the mobile device according to claim 1, wherein the wireless transceiver having signal path selection function is disposed at a proper location of the mobile device substrate and controlled by the master controller of the mobile device and provides three signal path selections:

a first signal path, the first signal path being comprised by the RFID antenna, the wireless transceiver and the smart card chip in the Combi-SIM card to form a wireless card function, the exterior wireless card reader accesses the electronic purse in the Combi-SIM card;

a second signal path, the second signal path being comprised by the mobile device master controller, the wireless transceiver and the smart card chip in the Combi-SIM card and enabling the mobile device to access the data content of the smart card of electronic purse in the Combi-SIM, the user inquires the transaction record, balance, added value or other ATM card transfer application; and

a third signal path, the third signal path being comprised by the RFID antenna, the wireless transceiver and the mobile device master controller and enabling the mobile device to work as a wireless card reader to access an exterior RFID tag, wherein herewith user acquires the related information from it.

4. The Combi-SIM card framework of electronic purse combining the wireless transceiver of the mobile device according to claim 1, wherein after the Combi-SIM card is inserted into the mobile device having a RF antenna and wireless transceiver built in, the mobile device is added with three functions besides the mobile telecommunication function:

a first function;

the mobile device works as a wireless card to be accessed by exterior wireless card reader, consumer uses the mobile device having the Combi-SIM card inserted as wireless card such as Easy Card, ATM card, Value Added Card or other electronic purse or electronic ticket without carrying additional card;

a second function;

the mobile device works as a card reader to read an exterior RFID tag data, wherein such a manner further broadens the application of the framework; and

a third function;

the mobile device accesses the smart card of electronic purse in the Combi-SIM directly to enable user to read or alter or set up its information content.
