Embodiment 3
Present embodiments provide a kind of method for building up of communication.This method can be by described in above-described embodiment 1 and 2
Device or system are realized.
Fig. 5 is the flow chart of the method for building up for the communication that the present embodiment provides, as shown in figure 5, the present embodiment offer is logical
The method for building up of letter mainly includes the following steps that：
Step S502, card reader cycle through card seeking instruction with a variety of different modulation systems respectively；
In the present embodiment, card reader supports Different Modulations, card reader can when receiving Card Reader instruction, start with
Different modulation systems cycles through card seeking instruction, supports different modulating mode card to can recognize that the modulation methods that itself is supported
The card seeking instruction that formula is sent, and then responded.
Step S504, card reader receive the card seeking for the card seeking instruction that the response one of which modulation system that card is sent is sent
Response；
In a particular application, for specifically applying card, its modulation system that can only identify itself to support is sent out
The card seeking instruction sent, after card seeking instruction is identified, card returns to card seeking response, and the response message in card seeking response can be with
The communications protocol configured information that card uses is carried, can not also be carried.
Step S506, the modulation system that card reader uses according to the instruction of the card seeking of above-mentioned card seeking response response determine card
Modulation type；
In a particular application, card reader can carry currently used tune when sending card seeking instruction in card seeking instruction
The configured information of mode processed, card can also carry the configured information, card reader when returning to card seeking response in card seeking response
The modulation type of card can be determined according to the configured information.Or card reader can also be sought being sent with a kind of modulation system
After card instruction, certain time is waited, if being not received by card seeking response, a kind of following modulation system sends card seeking instruction,
Until receiving card seeking response, the modulation methods used are instructed so as to which the card seeking that can also determine to receive responds responded card seeking
Formula, and then determine the modulation type of card, i.e., modulation type corresponding with the modulation system that the card seeking instruction of response uses.
Step S508, card reader are returned using modulation system corresponding with above-mentioned modulation type to card in card seeking flow
Response message is demodulated；
Step S510, card reader is according to the communications protocol configured information carried in the obtained response message of demodulation, it is determined that card
The communications protocol that piece uses；
Wherein, if the response message in the card seeking response that card returns carries communications protocol configured information, step
Response message in S508 is the response message in card seeking response, if communications protocol configured information, Card Reader can not also be carried
Device can send instruction (i.e. in card seeking flow bag to card again after modulatedemodulate recalls the information carried in card seeking response
Interacting containing multiple card reader and card), card can carry the communications protocol configured information in follow-up response message, read
Card device gets the communications protocol of card use by demodulating the response information acquisition communications protocol configured information.
Step S512, card reader are established with card using above-mentioned communications protocol and communicated.
Specifically, card reader can activate corresponding communications protocol, during subsequently being communicated with card, use
The communications protocol organizational command form.
The above method provided by the present embodiment, card reader cycle through card seeking with a variety of different modulation systems and referred to
Order, instructed so that corresponding card seeking can be recognized using the card of different modulating mode, and communications protocol is indicated
Information returns to card reader, so that card reader can know the communications protocol that card uses, and then make it that card reader can be with
Communicated from using the card of different modulation system and communications protocol, extend the function of card reader, improve operation
Convenience, cost is saved.
In an optional embodiment of the embodiment of the present invention, card reader is using the communications protocol and the card
Establish after communication, can also carry out corresponding application, such as Card Reader.Therefore, in the optional embodiment, card reader is being adopted
After being communicated with the communications protocol with card foundation, it can also be write using signaling format corresponding with the communications protocol
Need the application to card to instruct, then answered using modulation system corresponding with the modulation type of above-mentioned determination writing completion
Encoded with instruction, then send the application after encoding to card and instruct.
In above-mentioned optional embodiment, further, card reader to card send coding after application instruction after,
Card can respond application instruction, and returning to application accordingly to card reader responds instruction, and card reader receives card for that should answer
The application response instruction returned with instruction, is then rung using modulation system corresponding with the modulation type of above-mentioned determination to the application
It should instruct and be demodulated, obtaining card in the application response instruction obtained further according to the communications protocol of above-mentioned determination from demodulation sends
Response contents, and according to the response contents determine handle the response contents application type, then operation with application type pair
The application program answered, perform processing corresponding with the response contents.For example, if card is identity card, what card reader was sent should
It is Card Reader with instruction, then identity card returns to corresponding identity card Card Reader response, and the identity card that card reader returns according to identity card is read
Card response, starts corresponding application program-SAM (residence card verifying security control) application program, SAM application programs open
It is dynamic, card image is read from the card, i.e. SAM application programs are read out the associated verification of identity card flow with identity card
And the operation such as decryption, and then get the identity information stored in identity card.
In an optional embodiment of the embodiment of the present invention, card reader read from card card image it
Afterwards, card image can also be sent to terminal.After terminal receives card image, card image can be shown, can also be led to
Cross network and card image is sent to server etc., specific the present embodiment is not construed as limiting.
