In actual use, the radio-frequency card device in close distance radio frequency communication system of the present invention can also be issued by telecom operators, miniature IC-card in financial service business or Third-party payment operators issue close distance radio frequency communication of the present invention system, by miniature IC-card is loaded radio-frequency card device, so also can the function of telecommunications functions and financial service etc. simultaneously.
In close distance radio frequency communication system of the present invention, miniature IC-card has the standard communication interface of common contact-type IC-card and the miniature IC-card in two interfaces of Non-contact radio-frequency communication interface, has the following two kinds optional manner in use:
One, mobile terminal is directly used to carry out swiping the card, supplementing with money, miniature IC-card is loaded in radio-frequency card device, form radio-frequency card (radio-frequency card is assembled by radio-frequency card device and miniature IC-card), then radio-frequency card entirety is loaded the SIM card slot of mobile terminal, the radio communication passage provided by radio-frequency card device is carried out 2.4GHz with corresponding multi-frequency radio frequency card reader and communicates and transactional operation;
Two, when mobile terminal electricity is not enough or wish the miniature IC-card in mobile terminal to change time, miniature IC-card can be taken out from radio-frequency card device, then load in double-interface card cover, the signal utilizing the Non-contact radio-frequency communication interface on miniature IC-card and the antenna that double-interface card puts and corresponding multi-frequency radio frequency card reader to carry out 13.56MHz communicates and transactional operation.
Like this, when mobile terminal normally has electric at ordinary times, can miniature IC-card be loaded in radio-frequency card device, the SIM card slot loading mobile terminal uses, and when mobile terminal electricity deficiency, miniature IC-card can be taken out, load in double-interface card cover and use, very simple and convenient.
Therefore, close distance radio frequency communication system and method provided by the present invention, for operator provides the disposal environment adapting to different frequency card, and when not changing user mobile phone SIM card as far as possible or changing subscriber phone number, realize telecom operators, financial service business etc. and independently can issue respective card, promote that mobile payment is applied fast.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
