The present invention discloses a smart card communication method, a smart card, and an enhanced near field communication NFC terminal. The method is used for communication between the smart card and an NFC contactless front-end chip; when installing a contactless payment application, the smart card records a communication standard adopted by a contactless payment system corresponding to the contactless payment application, wherein the communication standard is identified by identification information provided by the contactless payment application; it further comprises: for each card application gate, the smart card judges whether a contactless payment application corresponding to the card application gate exists based on the identification information; if yes, creating a pipe between the card application gate and a corresponding card RF gate in the NFC contactless front-end chip.

1. A communication method, for communication between a smart card and an NFC contactless front-end chip, comprising: when installing a contactless payment application, the smart card recording a communication standard adopted by a contactless payment system corresponding to the contactless payment application, wherein the communication standard is identified by identification information provided by the contactless payment application; further comprising: for each card application gate, the smart card judging whether a contactless payment application corresponding to the card application gate exists based on the identification information; if yes, creating a pipe between the card application gate and a corresponding card RF gate in the NFC contactless front-end chip, and then performing, by the smart card, contactless payment related to the contactless payment system;wherein the step that the contactless payment application provides the identification information comprises: a contactless payment application program provides the identification information about the communication standard adopted by the corresponding contactless payment system in a version number; and wherein the program version number of the contactless payment application has a format of: AP ‘an identifier of communication standard’ ‘version number’; and the identifier of the communication standard is represented by letters. 2. The method according to claim 1, further comprising: if no contactless payment application corresponding to the card application gate exists, no pipe being created between the card application gate and the corresponding card RF gate in the NFC contactless front-end chip. 3. The method according to claim 1, wherein the step of recording a communication standard adopted by a contactless payment system corresponding to the contactless payment application comprises: recording information about the payment application in a registry of the smart card; and the information about the payment application comprises identification information about the communication standard adopted by the contactless payment system corresponding to the contactless payment application. 4. The method according to claim 1, wherein the communication standard adopted by the contactless payment system is a communication standard corresponding to a communication technology adopted by communications between a contactless card in the contactless payment system or a terminal equipment serving as a contactless card and a card reader in the contactless payment system. 5. The method according to claim 1, wherein the step of judging comprises: the smart card queries in information about installed contactless payment application recorded in the smart card through the identification information, and judges whether a contactless payment application corresponding to the card application gate exists. 6. The method according to claim 1, wherein the contactless payment application corresponding to the card application gate comprises one or more contactless payment applications installed in the smart card; and the communication standard adopted by the contactless payment system corresponding to the contactless payment application is identical to the communication standard corresponding to the card application gate. 7. A smart card, comprising a recording unit, a judging unit and a pipe creating unit, wherein the recording unit is used for recording a communication standard adopted by a contactless payment system corresponding to a contactless payment application during installing the contactless payment application, and the communication standard is identified by identification information provided by the contactless payment application;the judging unit is used for determining, for each card application gate in the smart card, whether a contactless payment application corresponding to the card application gate exists through the identification information, and notifying the pipe creating unit if it exists; andthe pipe creating unit is used for creating a pipe between the card application gate and a corresponding card RF gate in an NFC contactless front-end chip based on notification from the judging unit, and used for performing contactless payment related to the contactless payment system;wherein the identification information is contained in a version number of the contactless payment application; and wherein the program version number of the contactless payment application has a format of: AP ‘an identifier of communication standard’ ‘version number’; and the identifier of the communication standard is represented by letters. 8. The smart card according to claim 7, wherein the contactless payment application corresponding to the card application gate comprises one or more contactless payment applications installed in the smart card; and the communication standard adopted by the contactless payment system corresponding to the contactless payment application is identical to the communication standard corresponding to the card application gate. 9. An eNFC terminal supporting a contactless payment application, comprising an NFC contactless front-end chip with more than one card RF gate and a smart card with more than one card application gate, wherein the smart card comprises: a recording unit, for recording a communication standard adopted by a contactless payment system corresponding to a contactless payment application during installing the contactless payment application, and the communication standard is identified by identification information provided in advance by the contactless payment application;a judging unit, for determining, for each card application gate in the smart card, whether a contactless payment application corresponding to the card application gate exists through querying the identification information, and notifying a pipe creating unit if it exists; anda pipe creating unit, for creating a pipe between the card application gate and the corresponding card RF gate in the NFC contactless front-end chip based on notification from the judging unit, and for performing contactless payment related to the contactless payment system;wherein the step that the contactless payment application provides the identification information comprises: a contactless payment application program provides the identification information about the communication standard adopted by the corresponding contactless payment system in a version number; and wherein the program version number of the contactless payment application has a format of: AP ‘an identifier of communication standard’ ‘version number’; and the identifier of the communication standard is represented by letters. 10. The terminal according to claim 9, wherein the step of recording a communication standard adopted by a contactless payment system corresponding to the contactless payment application comprises: recording information about the payment application in a registry of the smart card; and the information about the payment application comprises identification information about the communication standard adopted by the contactless payment system corresponding to the contactless payment application. 11. The terminal according to claim 9, wherein the contactless payment application corresponding to the card application gate comprises one or more contactless payment applications installed in the smart card; and the communication standard adopted by the contactless payment system corresponding to the contactless payment application is identical to the communication standard corresponding to the card application gate.
