Brief description of the drawings
Fig. 1 is the principle process schematic diagram of the inventive method；
Fig. 2 is the composition structural representation of present system；
Fig. 3 is the schematic flow sheet that the inventive method embodiment user selects different concrete applications.
Embodiment
The present invention basic thought be：The card applied with Desfire is applied in compatibility Mifare built in user terminal, by
Equipment and user terminal communication, card judge whether to need seven byte unique user identification code UID according to the instruction of equipment card seeking
Rear four bytes replace with the UID of Mifare types, should further according to rear four bytes UID types automatic identification selection Mifare
With or Desfire using being communicated with equipment.
In the present invention, there are Desfire cards seven byte UID, Mifare cards to have nybble UID；The automatic identification is
A kind of adaptive certification, refers to after equipment communication instruction is received, and Desfire cards and Mifare cards are different from each by one
Seven UID, new byte UID make certification, and the seven new byte UID are by first three byte in the byte UID of Desfire cards seven
Constituted with the UID of Mifare card nybbles；Specifically, card protocol layer is sent into byte in two times, is for the first time Desfire cards
First three byte in UID, second of nybble UID for Mifare cards.
The implementation to technical scheme is described in further detail below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of realize more than a card comprises the following steps using the method for self-adapting estimation：
Step 101, equipment and user terminal communication, are applied and Desfire applications in compatibility Mifare built in user terminal
Card.
When step 102, equipment read card, card judges whether to need uniquely to use seven bytes according to the instruction of equipment card seeking
Family identification code UID rear four bytes replace with the UID of Mifare types, further according to rear four bytes UID type automatic identifications
Selection Mifare applications or Desfire are applied to be communicated with equipment.
Here, if rear four bytes for the seven byte UID that card is returned are replaced by the nybble UID of Mifare types
Change, then identify currently as Mifare applications；If rear four bytes for the seven byte UID that card is returned are not by Mifare types
Nybble UID replace, illustrate still be Desfire types UID, then identify currently for Desfire apply.
It need to be noted that be：It is the succession technology on the basis of Mifare because Desfire is under the jurisdiction of Mifare,
Therefore, the instruction request content of the two is the same, for equipment side, and bad differentiation is that Desfire applications are gone back on earth
It is Mifare applications, and CPU applies quite different, instruction request content is applied from Desfire and Mifare applications are different, facilitates machine
Tool side makes a distinction.Therefore, the present invention is that, as a class, CPU is applied and is used as another kind of carry out area using Desfire and Mifare
Point, and in of a sort Desfire and Mifare, due to being inheritance, bad differentiation is sent in two times using the present invention
New 7 byte UID carry out Desfire and Mifare automatic identification.
CPU applications are put aside, subsequently there is concrete example description；Here, only describe to be difficult to differentiate between is of a sort
Desfire is applied and Mifare applications.Although as the instruction request content that Desfire is applied with Mifare is applied, two
The instruction format of person is different, specifically, when realizing that Desfire is applied, the UID of seven bytes must be sent to by Desfire cards
Equipment could form stable communication for identification between equipment and card, complete the processing of subsequent instructions；And realizing
When Mifare is applied, the UID for the nybble that Mifare cards must solidify card is sent to equipment for identification, could be in equipment
Stable communication is formed between card, the processing of subsequent instructions is completed.That is, the UID of seven bytes is Desfire types
UID, and the UID of nybble is the UID of Mifare types.
In view of this, applied in equipment with built-in compatible Mifare and the user terminal of Desfire application cards is led to
Letter, during equipment Card Reader, in order to realize that Mifare applies the automatic identification applied with Desfire with minimum change, to improve use
Convenience that family is used and cost is reduced, still send the UID of seven bytes, but otherwise varied be：The UID of seven bytes is divided to two
It is secondary to be sent to equipment, first send out first three byte, then four bytes after sending out, if second of rear four byte sent is by Mifare
The nybble UID of type is replaced, then for current transmission, and card performs corresponding Mifare applications；If second of transmission
Four bytes are not replaced by the nybble UID of Mifare types afterwards, then illustrate the UID still for Desfire types, will send out twice
After the UID for the Desfire types sent is reconfigured, card performs corresponding Desfire applications.
In the prior art, when being communicated due to Mifare cards and Desfire cards, the UID forms for being sent to equipment are different,
There is the difference of seven bytes and nybble, user is required for independently specifying tool when applying using Mifare and Desfire every time
Body application, i.e.,：Manually operated STK menus carry out the manual identification and switching that Mifare is applied and Desfire is applied, if desired for brush
Public transport（Desfire）The equipment of application, it is necessary to be switched to Desfire patterns by hand in SIM cards of mobile phones application menu；Such as need to be
Enterprise gate inhibition（Mifare）Using, it is necessary to be switched to Mifare moulds by hand in SIM cards of mobile phones application menu in the equipment of application
Formula.
Using the present invention, the deficiency of existing Desfire and Mifare compatibilities but Card Reader identification and switching, user are solved
When Card Reader is recognized, without knowing which concrete application used（Desfire or Mifare）, the UID returned according to card is with regard to energy
Automatic identification and the switching for carrying out corresponding concrete application function, it is smooth perfect on the premise of any transformation is not done to equipment
Ground realizes that Desfire and Mifare Auto-matchings related application is instructed, and improves the practicality of Desfire and Mifare technologies,
The convenience that lifting user uses, reduces cost.
