In actual use; Operator or financial service merchant are through laying POS (the Point of Sales that disposes above-mentioned multi-frequency radio frequency card reader in each outlet; The point of sale) main frame can be accepted any transaction business that carries out that adopts in above-mentioned two kinds of different frequency radio communications.
In actual use; Can issue the miniature IC-card in the close distance radio frequency communication of the present invention system by telecom operators; Financial service merchant or third party pay the radio-frequency card device in the distribution close distance radio frequency communication of the present invention system of operator; Through radio-frequency card device that miniature IC-card is packed into, can realize telecommunications functions and financial service function simultaneously like this.
In actual use; Can also issue the radio-frequency card device in the close distance radio frequency communication of the present invention system by telecom operators; Financial service merchant or third party pay the miniature IC-card in the distribution close distance radio frequency communication of the present invention system of operator; Through radio-frequency card device that miniature IC-card is packed into, so also functions such as telecommunications functions and financial service simultaneously.
In the close distance radio frequency communication of the present invention system, miniature IC-card is to have the standard communication interface of common contact-type IC-card and the miniature IC-card in two interfaces of noncontact radio communication interface, and following two kinds of optional modes are arranged in use:
One, uses that directly portable terminal is swiped the card, supplemented with money etc.; Miniature IC-card is packed in the radio-frequency card device; Form radio-frequency card (radio-frequency card is assembled by radio-frequency card device and miniature IC-card); Then with pack into the SIM slot of portable terminal of radio-frequency card integral body, the radio communication passage that provides through the radio-frequency card device and corresponding multi-frequency radio frequency card reader are carried out the 2.4GHz operation of communicating by letter and conclude the business;
Two, not enough or when hoping the miniature IC-card in the portable terminal changed when the portable terminal electric weight; Can miniature IC-card be taken out from the radio-frequency card device; In the double-interface card of packing into the then cover, the antenna that utilizes noncontact radio communication interface and double-interface card on the miniature IC-card to put carries out the signal communication of 13.56MHz with corresponding multi-frequency radio frequency card reader and concludes the business and operate.
Like this, normally have at portable terminal at ordinary times under the situation of electricity, can miniature IC-card be loaded in the radio-frequency card device; The SIM slot of portable terminal of packing into uses, and under the not enough situation of portable terminal electric weight, can miniature IC-card be taken out; Use in the double-interface card of packing into the cover, very simple and convenient.
Therefore; Close distance radio frequency communication system and method provided by the present invention; The disposal environment that adapts to the different frequency card is provided for operator; And under the situation of not changing user mobile phone SIM or change subscriber phone number as far as possible, realize that telecom operators, financial service merchant etc. can both independently issue card separately, promote mobile payment to apply fast.
The above is merely preferred embodiment of the present invention, and is in order to restriction the present invention, not all within spirit of the present invention and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
