The association information corresponding to the AID of the mode application X is provided to the client module, and the association information corresponding to the AID of the card simulation mode application X includes at least: a downloading uniform resource locator (URL, Uniform Resource Locator) address of the card simulation mode application X .

The application discovery module is configured to find the association information corresponding to the AID of the card simulation mode application X according to the saved AID of the different card simulation mode application and the corresponding association information, and return the information to the security module.

The NFC terminal shown in Figure 1 may further include: an antenna, an NFC controller, and an operating system module.

The security module may send the association information corresponding to the AID of the card simulation mode application X to the NFC controller in the form of an event. Specifically, the security module may combine the association information corresponding to the AID of the card simulation mode application X into a parameter string, and The parameter string is sent to the NFC controller in the form of an event; correspondingly, the NFC controller reports the received event to the operating system module; the client module obtains the reported event from the operating system module, and extracts the event from the operating system module. The card emulation mode applies the association information corresponding to the AID of X.

In addition, the transaction request received by the security module is obtained by the NFC controller from the receiving environment through the antenna and processed and sent to the security module.

The association information corresponding to the AID of the card emulation mode application X may further include: a name of the card emulation mode application X; correspondingly, the client module may be further used to apply the card emulation mode before downloading the card emulation mode application X The name of X is displayed to the user, and the user is asked if they are allowed to The card emulation mode application X, if a confirmation command is received, downloads the card emulation mode application X.

The association information corresponding to the AID of the card emulation mode application X may further include: the offer information of the card emulation mode application X; correspondingly, the client module may be further used to display the name of the card emulation mode application X to the user At the same time, the card simulation mode application X preferential information is displayed to the user to attract the user to use the card simulation mode application X, thereby facilitating the promotion of the card simulation mode application X. When the NFC terminal shown in Figure 1 performs a card swipe operation (usually a non-contact card swipe operation), the workflow of each module can be as follows: 1) fly).

1) The NFC controller receives a transaction request initiated by a device such as a POS machine in a non-contact receiving environment through an antenna, and the transaction request is usually a 13.56 M radio frequency signal; the NFC controller converts the radio frequency signal into a digital signal and sends it to the security. Module.

2) After receiving the transaction request, the security module sends the AID of the card emulation mode application X carried in the transaction request to the application discovery module if it is determined that the card emulation mode application X corresponding to the card swiping operation is not installed.

3) The AID of the application of the different card simulation mode and its corresponding association information are pre-stored in the application discovery module, and the AID of each card simulation mode application and its corresponding association information can be saved in the structure of a mapping data table.

FIG. 3 is a schematic structural diagram of each mapping data table of the present invention. As shown in FIG. 3, other information except the AID information may be collectively referred to as associated information, and the associated information at least includes: downloading a URL address, and may also include a name and other information, and other information such as a preferential information, etc. .

It also includes the name of the card emulation mode application X, the download URL address, and the offer information.

4) The security module combines the associated information corresponding to the AID of the card simulation mode application X into a parameter string, or the associated information corresponding to the AID of the received card simulation mode application X and the AID of the card simulation mode application X. A parameter string is synthesized, and the latter method is assumed in the embodiment; the parameter string is a variable length structure, and a combination of "AID + name + download URL address + preferential information" can be adopted. The security module sends the combined parameter string to the NFC controller in the form of an event.

5) The NFC controller reports the received event to the operating system module.

6) The client module can open a service process for monitoring events reported from the NFC controller to the operating system module and can parse the received events.

Correspondingly, when the client module listens to the event reported by the NFC controller to the operating system module in step 5), parses the event, and extracts the association information corresponding to the AID of the card simulation mode X or the card simulation mode X. The associated information corresponding to the AID and the AID of the card emulation mode X.
