Using contactless two generations shield mode.
Further, as described above by the method for judging that communication interface determines application model, when using non-contact card
When mode, Bluetooth RF chip is not powered, and double interface financial IC card chips are powered by RF antenna；When two generation shield mode of application,
Double interface financial IC card chips are powered by RF antenna, and Bluetooth RF chip is then by IC card in-line power.
Further, as described above by the method for judging that communication interface determines application model, in the step (3),
When meeting the agreement, double interface financial IC cards further pass through SPI or UART interface is attempted and Bluetooth RF chip
Communication, if communication failure, IC card application contact mode card；Conversely, communicating successfully, IC card application contact two generations shield mode.
Further, as described above by the method for judging that communication interface determines application model, when application contacts card mold
When formula, Bluetooth RF chip is not powered, and double interface financial IC card chips are passed through the VCC of IC card contact by equipment such as external card reader
Contact power supply；When application two generation of contact shield mode, Bluetooth RF chip is powered by the contact VDD of IC card contact, and double boundaries
Face financial IC card chip is powered by the contact VCC of IC card contact.
Further, as described above by the method for judging that communication interface determines application model, when using bluetooth shield mould
When formula, Bluetooth RF chip and double interfaces financial IC card chip are powered by internal electric source.
Further, as described above by the method for judging that communication interface determines application model, double interface finance
IC card includes Power power button, if not pressing the key, IC card internal electric source does not give the Bluetooth RF chip to power,
If instead pressing the key, Bluetooth RF chip is powered.
By with the application of the invention, judging the state of communication interface determines application model that IC card is currently located in, and then give
Next such as initialization operating process is prepared.
Detailed description of the invention
Fig. 1 is double interface financial IC card block diagrams used in the present invention.
Fig. 2 is method flow diagram used in the present invention.
Specific embodiment
The present invention is described in detail below with reference to the accompanying drawings and embodiments.
The block diagram of double interfaces financial IC card involved in the method for the invention is as shown in Figure 1.A kind of multifunction IC card, packet
It includes double-interface card chip 2, the RF antenna 1 that connect with double-interface card chip 2 and IC card contact 7, further includes and the double-interface card
The Bluetooth RF chip 3 that chip 2 connects, Bluetooth RF chip 3 are whole by Bluetooth RF antenna 5 and outside bluetooth-capable
End equipment communication connection；It further include that the key 4 connecting with Bluetooth RF chip 3 and LCD show 6.
Firstly, double interface financial IC card chips are powered, and judge whether the card chip is in radio-frequency magnetic place；If card
Chip is in radio-frequency magnetic place, then further judges whether card chip can communicate with non-contact card-reading apparatus, if it is, IC
Card applies non-contact card mode or contactless two generations shield mode；If it is not, then judging that card chip is damaged；If unidentified arrive radio frequency
Field regions, then the card chip judges whether the pin of IC card contact meets ISO7186 agreement, if meeting the agreement,
IC card application contact mode card or contact two generations shield mode；If not meeting the agreement, IC card application bluetooth shield mode.
As shown in Fig. 2, specifically, the workflow of method of the invention is as follows:
(1), when double interface financial IC card chips 2 power on, the card chip first determines whether that outside contactless card-reading apparatus is
It is no to have card reading operation, that is, judge whether card chip is in radio-frequency magnetic place.If in radio-frequency magnetic place card chip can with it is non-
Card-reading apparatus communication is contacted, IC card application model will be " non-contact card " or noncontact mode " two generation shields " application.
(2), double interface financial IC cards have a Power power button 4, and user wishes that equipment works " non-contact card "
It when mode, will not be switched on by Power power button, IC card internal electric source will not power to Bluetooth RF chip at this time, conversely, blue
Tooth radio frequency chip 3 will power.If double interface financial IC cards wish to be applied to " non-contact card " mode, the card chip is sentenced
Break after having RF radio frequency, it will be by SPI or UART interface trial and Bluetooth RF chip communication, at this point, due to Bluetooth RF chip
It does not power, the communication between double interface financial IC card chips and Bluetooth RF chip will fail, therefore card chip will judge currently
It should be " non-contact card " mode., whereas if being supplied with electric power by Power power key to Bluetooth RF chip, card chip judges that RF is penetrated
After frequency, the communication with Bluetooth RF chip will succeed, and card chip will judge that equipment should be at " two generations of noncontact mode accordingly
Shield " application.When " non-contact card " application model, Bluetooth RF chip is not powered, and double interface financial IC card chips are supplied by RF antenna 1
Electricity." the two generation shields " of noncontact mode is in application, double interface financial IC card chips are powered by RF, and Bluetooth RF chip is by IC card
Portion's power supply.
(3), in above-mentioned step 2 operation, if unidentified to there is RF RF magnetic field, double interface financial IC card chips will be sentenced
Whether the pin of disconnected IC card contact meets ISO7186 agreement, and (IC card is communicated with equipment such as external contact card reader, ATM machine
Agreement is ISO7816).If meeting consensus standard, the equipment application mode will be " contact card " or contact mode " two generations
Shield " application.Next judgement is identical as step 2, when double interface financial IC cards are attempted with Bluetooth RF chip communication, such as
Fruit communication failure, IC card will be applied as " contact card " mode；Conversely, communicating successfully, IC card will be applied to " two generations of contact mode
Shield ".When " contact card " application model, Bluetooth chip is not powered, and double interface financial IC card chips are led to by equipment such as external card reader
Cross the first contact power supply of IC card contact 7." the two generation shields " of contact mode in application, Bluetooth chip by the 4th of IC card contact 7
Contact power supply, and double interface financial IC card chips are powered due to the first contact of IC card contact 7.
(4), in above-mentioned step 3 operation, if not accessing the equipment such as satisfactory card reader, ATM machine, i.e. ISO7816 is logical
Letter failure, double interface financial IC card chips, which will be considered to IC card, to be applied to " bluetooth shield mode "." bluetooth shield " application model
When, Bluetooth RF chip and double interfaces financial IC card chip are powered by internal electric source.
Obviously, various changes and modifications can be made to the invention without departing from essence of the invention by those skilled in the art
Mind and range.If in this way, belonging to the model of the claims in the present invention and its equivalent technology to these modifications and changes of the present invention
Within enclosing, then the present invention is also intended to include these modifications and variations.
