Fig. 4 is a signaling diagram of an application processing method according to an embodiment of the present application. As shown in fig. 4, the method may include:

S401, the terminal equipment receives a card selection instruction sent by the collection equipment, wherein the card selection instruction is used for indicating an application identifier (application identifier, AID).

For example, when the terminal device approaches the collection device and the transaction needs to be completed, the collection device sends out field intensity information, and the field intensity information is a card selection instruction; the card selection instruction sent by the collection equipment carries the AID of the card application, or the card selection instruction sent by the collection equipment characterizes the AID of the card application. In this embodiment, the card selection instruction received by the terminal device indicates an AID of a card application.

S402, the terminal equipment determines the card application corresponding to the AID indicated by the card selection instruction according to the AID list, wherein the AID list is used for indicating the corresponding relation between the AID and the card application.

Illustratively, an AID list has been pre-stored in the terminal device. The AID list comprises at least one AID of the card application, and further the AID list indicates the corresponding relation between the AID and the card application; alternatively, the AID list includes a correspondence between each AID and each card application. And, the card applications indicated by the AID list are payment applications. The payment application includes: bank cards, cards of digital RMB, traffic cards, access cards, cards corresponding to car keys.

For example, table 1 is an AID list, and when AID is xxx1, as shown in table 1, the indicated card application is card application a; when the AID is xxx2, the indicated card application is a card application b; when the AID is xxx3, the indicated card application is a card application c; when the AID is xxx4, the indicated card application is card application d; when the AID is xxx5, the indicated card application is a card application e; when AID is xxx6, the indicated card application is card application f.

Table 1 AID list

AID	Card application
		xxx1	Card application a
xxx2	Card application b
		xxx3	Card application c
xxx4	Card application d
		xxx5	Card application e
xxx6	Card application f
		xxx7	Card application g
xxx8	Card application h

The AID list may further include specific categories of each card application, where the specific categories are: bank cards, cards of digital rmbs, traffic cards, and access cards.

For example, table 2 is an AID list, and when AID is xxx1, the indicated card application is a card application a, which is a bank card; when the AID is xxx2, the indicated card application is card application b, and the card application b is a bank card; when the AID is xxx3, the indicated card application is card application c, and the card application c is a digital RMB card; when the AID is xxx4, the indicated card application is card application d, and the card application d is an access control card; when the AID is xxx5, the indicated card application is card application e, and the card application e is an access control card; when the AID is xxx6, the indicated card application is card application f, which is a traffic card.

Table 2 AID list

AID	Card application	Specific category
			xxx1	Card application a	Bank card
xxx2	Card application b	Bank card
			xxx3	Card application c	Digital RMB card
xxx4	Card application d	Access control card
			xxx5	Card application e	Access control card
xxx6	Card application f	Traffic card

In one example, the cloud server may send the AID list to the terminal device, and the terminal device may receive and store the AID list. For example, the cloud server is an application management server of the terminal device.

At this time, the cloud server may update the AID list, and then send the updated AID list to the terminal device. For example, the cloud server automatically updates the AID list, and sends the updated AID list to the terminal device. For another example, the terminal device sends update information to the cloud server, where the update information is used to indicate the AID and the card application to be deleted; the cloud server modifies the AID list corresponding to the terminal equipment according to the updating information, deletes the AID and the card application indicated by the updating information from the AID list corresponding to the terminal equipment, and obtains an updated AID list; and the cloud server sends the updated AID list to the terminal equipment. For another example, the terminal device sends update information to the cloud server, where the update information is used to indicate an AID and a card application to be added; the cloud server modifies the AID list corresponding to the terminal equipment according to the updating information, and adds the AID and the card application indicated by the updating information into the AID list corresponding to the terminal equipment to obtain an updated AID list; and the cloud server sends the updated AID list to the terminal equipment.

In another example, the AID list is generated for the terminal device. When the terminal equipment installs the application program of the card application, the AID of the card application can be stored in an eSE chip of the terminal equipment; when the terminal equipment uses the applet of the card application, the AID of the card application can be stored in the eSE chip of the terminal equipment; thus, the terminal device can read all the AIDs in the eSE chip and generate an AID list according to all the AIDs. Or when the terminal equipment installs the application program of the card application, the terminal equipment can acquire the AID of the card application, and further store the corresponding relation between the AID and the card application; when the terminal equipment uses the applet of the card application, the terminal equipment can also acquire the AID of the card application, and further store the corresponding relation between the AID and the card application; thus, the terminal device may generate an AID list.

At this time, the terminal device may automatically update the AID list; the terminal device may update the AID list according to the use condition of the card application. For example, when downloading an application program of a card application, the terminal device may acquire an AID of the card application, add the AID of the card application to the AID list, and then update the AID list. For another example, when the terminal device uses the applet of the card application, the terminal device may acquire the AID of the card application, add the AID of the card application to the AID list, and then update the AID list. For another example, when the terminal device uninstalls the application program of the card application, the AID of the card application is deleted from the AID list, and then the AID list is updated. For another example, if the terminal device does not use a card application within a preset period of time, it is determined that the AID of the card application is deleted from the AID list, and then the AID list is updated.

After receiving the card selection instruction, the terminal equipment determines the card application corresponding to the AID indicated by the card selection instruction according to the AID list.

For example, if the card selection instruction indicates that the AID is xxx1, the terminal device may determine that the card application is card application a according to table 1; and if the card selection instruction indicates that the AID is xxx2, the terminal equipment can determine that the card application is the card application b according to the table 1.

In the step, the card applications corresponding to the AID stored in the AID list are all card applications supported by the terminal device. Therefore, if the terminal equipment can determine the card application corresponding to the AID indicated by the card selection instruction if the AID list, the terminal equipment is indicated to support the card application corresponding to the AID indicated by the card selection instruction; if the terminal equipment determines that the card application corresponding to the AID indicated by the card selection instruction does not exist in the AID list according to the AID list, the terminal equipment indicates that the terminal equipment does not support the card application corresponding to the AID indicated by the card selection instruction.

S403, if the terminal equipment determines that the card application corresponding to the AID indicated by the card selection instruction is not the current default payment application, activating the card application corresponding to the AID indicated by the card selection instruction.

Illustratively, in step S402, the terminal device may determine, according to the AID list by the terminal device, a card application corresponding to the AID indicated by the card selection instruction, and indicate that the terminal device supports the card application corresponding to the AID indicated by the card selection instruction. The terminal equipment needs to judge whether the card application corresponding to the AID indicated by the card selection instruction is the current default payment application of the terminal equipment.

In one example, the terminal device may invoke an AID of a current default payment application of the terminal device, and compare the AID indicated by the card selection instruction with the AID of the current default payment application of the terminal device; if the card application and the card application are consistent, the terminal equipment determines that the card application corresponding to the AID indicated by the card selection instruction is the current default payment application; if the card application and the card application are inconsistent, the terminal equipment determines that the card application corresponding to the AID indicated by the card selection instruction is not the current default payment application.

In another example, the correspondence between the AID and the name of the card application is stored in table 1, so that the terminal device may determine the name of the card application of the AID indicated by the card selection instruction; the terminal equipment invokes the name of the current default payment application, and then compares the name of the card application of the AID indicated by the card selection instruction with the name of the current default payment application; if the card application and the card application are consistent, the terminal equipment determines that the card application corresponding to the AID indicated by the card selection instruction is the current default payment application; if the card application and the card application are inconsistent, the terminal equipment determines that the card application corresponding to the AID indicated by the card selection instruction is not the current default payment application.

By adopting the mode, if the terminal equipment determines that the card application corresponding to the AID indicated by the card selection instruction is not the current default payment application, the terminal equipment determines that the current default payment application of the terminal equipment cannot be adopted for carrying out the payment transaction process; in order to complete the transaction process, the terminal device needs to automatically activate the card application corresponding to the AID indicated by the card selection instruction, so that the card application is in a transaction state.

S404, if the terminal equipment determines that the card application corresponding to the AID indicated by the card selection instruction is not the current default payment application, the card application corresponding to the AID indicated by the card selection instruction is set as the default payment application.

The terminal device adopts the method in step S403, and if it is determined that the card application corresponding to the AID indicated by the card selection instruction is not the current default payment application, the terminal device determines that the payment transaction process cannot be performed by using the current default payment application of the terminal device. At this time, the terminal device sets the card application corresponding to the AID indicated by the card selection instruction as a default payment application of the terminal device, thereby automatically modifying the default payment application.

For example, the terminal device receives a card selection instruction, where the card selection instruction indicates that one AID is xxx2; the terminal equipment determines that the card application corresponding to the xxx2 is the card application b, and determines that the terminal equipment supports the card application b; the current default payment application of the terminal equipment is a card application a, and further, if the terminal equipment determines that the card application b is not the current default payment application of the terminal equipment, the terminal equipment sets the default payment application as the card application b, and activates the card application b to be in a transaction state.

After the terminal device modifies the default payment application, the terminal device automatically modifies the option of the default payment application in the list of the default payment application of the terminal device.

When the terminal device automatically modifies the option of the "default payment application", the following several ways may be used.

Step S405 is an optional step.

S406, the terminal equipment sends a selection confirmation result to the collection equipment, wherein the selection confirmation result is used for representing that the terminal equipment supports card application corresponding to the AID indicated by the card selection instruction.

Illustratively, since the terminal device determines the card application corresponding to the AID indicated by the card selection instruction at step S402, the terminal device determines to support the card application corresponding to the AID indicated by the card selection instruction. After the terminal device activates the card application corresponding to the AID indicated by the card selection instruction, the terminal device generates a selection confirmation result, and at this time, the selection confirmation result characterizes the terminal device to support the card application corresponding to the AID indicated by the card selection instruction.

In addition, the selection confirmation result may include the following: the AID indicated by the card selection instruction and transaction content. Transaction content, including but not limited to: terminal equipment identification, transaction amount, transaction identification.

The card application server processes the transaction according to the transaction instruction, and then sends transaction result information to the terminal equipment, wherein the transaction result information represents whether the transaction is successful or not.

For example, the card application corresponding to the AID indicated by the card selection instruction is a digital RMB card, and the collection device generates a transaction instruction, where the transaction instruction includes the AID, the transaction identifier, the transaction amount, the transaction time, the account name, and the like of the digital RMB card. The collection equipment sends a transaction instruction to the terminal equipment; and the terminal equipment sends the transaction instruction to a card application server, wherein the card application server is a server of the digital RMB card. The card application server performs transaction processing according to the information in the transaction instruction, generates transaction result information, sends the transaction result information to the terminal device, and then the terminal device sends the received transaction result information to the collection device.

In yet another example, the checkout device sends the transaction instructions to the terminal device; the collection device also sends a transaction instruction to the card application server; the card application server is a server to which the card application corresponding to the AID indicated by the card selection instruction belongs. The card application server processes the transaction according to the transaction instruction, and then sends transaction result information to the terminal equipment, wherein the transaction result information represents whether the transaction is successful or not. The terminal device sends the transaction result information to the collection device.

For example, the card application corresponding to the AID indicated by the card selection instruction is a bank card, and the collection device generates a transaction instruction and sends the transaction instruction to the terminal device and the card application server; the card application server is a server to which the card application corresponding to the AID indicated by the card selection instruction belongs, and the transaction instruction comprises the AID of the bank card, a transaction identifier, a transaction amount, a transaction time, an account name and the like. The card application server performs transaction processing according to the information in the transaction instruction, then generates transaction result information, and sends the transaction result information to the terminal device, wherein the transaction result information represents whether the transaction processing is successful or not. Then, the transaction result information received by the terminal device is transmitted to the collecting device.

Fig. 29 is a signaling diagram of yet another application processing method according to an embodiment of the present application. As shown in fig. 29, the method may include:

s2901, the terminal equipment receives a card selection instruction sent by the cash register equipment, wherein the card selection instruction is used for indicating a plurality of AIDs.

For example, when the terminal device approaches the collection device and the transaction needs to be completed, the collection device sends out field intensity information, and the field intensity information is a card selection instruction; the card selection instruction sent by the collection device carries the AIDs of the plurality of card applications, or the card selection instruction sent by the collection device characterizes the AIDs of the plurality of card applications. In this embodiment, the card selection instruction received by the terminal device indicates an AID of each of the plurality of card applications.

S2902, the terminal equipment determines each card application corresponding to each AID indicated by the card selection instruction according to the AID list, wherein the AID list is used for indicating the corresponding relation between the AID and the card application.

Illustratively, an AID list has been pre-stored in the terminal device. The AID list may be referred to in the introduction of step S402. In the step, the card applications corresponding to the AID stored in the AID list are all card applications supported by the terminal device. Therefore, for each AID indicated by the card selection instruction, if the terminal equipment can determine the card application corresponding to the AID indicated by the card selection instruction according to the AID list, the terminal equipment is indicated to support the card application. For each AID indicated by the card selection instruction, if the terminal equipment determines that the card application corresponding to the AID indicated by the card selection instruction does not exist in the AID list according to the AID list, the terminal equipment indicates that the terminal equipment does not support the card application.

S2903, if the terminal equipment determines that each card application corresponding to each AID indicated by the card selection instruction is not the current default payment application, determining the card application to be transacted from each card application corresponding to each AID indicated by the card selection instruction, and activating the card application to be transacted.

For each AID indicated by the card selection instruction, in step S2902, since it is determined that the card application corresponding to the AID indicated by the card selection instruction has been determined according to the AID list, it is determined that the terminal device supports the card application. Further, for the card application supported by the terminal device (at this time, the card application is the card application corresponding to the AID indicated by the card selection instruction), the terminal device needs to determine whether the card application corresponding to the AID indicated by the card selection instruction is the current default payment application of the terminal device.

In one example, for each AID indicated by the card selection instruction, the terminal device may invoke an AID of a current default payment application of the terminal device, and compare the AID indicated by the card selection instruction with the AID of the current default payment application of the terminal device; if the card application and the card application are consistent, the terminal equipment determines that the card application corresponding to the AID indicated by the card selection instruction is the current default payment application; if the card application and the card application are inconsistent, the terminal equipment determines that the card application corresponding to the AID indicated by the card selection instruction is not the current default payment application.

In another example, the correspondence between the AID and the name of the card application is stored in table 1, so that the terminal device may determine the name of the card application of the AID indicated by the card selection instruction; aiming at each AID indicated by the card selection instruction, the terminal equipment invokes the name of the current default payment application, and then compares the name of the card application of the AID indicated by the card selection instruction with the name of the current default payment application; if the card application and the card application are consistent, the terminal equipment determines that the card application corresponding to the AID indicated by the card selection instruction is the current default payment application; if the card application and the card application are inconsistent, the terminal equipment determines that the card application corresponding to the AID indicated by the card selection instruction is not the current default payment application.

By adopting the mode, if the terminal equipment determines that each card application corresponding to each AID indicated by the card selection instruction is not the current default payment application, the terminal equipment determines that the current default payment application of the terminal equipment cannot be adopted for carrying out the payment transaction process; in order to complete the transaction process, the terminal device needs to determine a card application to be transacted from each card application corresponding to each AID indicated by the card selection instruction. Then, the terminal device automatically activates the card application to be transacted to put the card application in a transaction state.

In one example, if each card application corresponding to each AID indicated by the card selection instruction is not a default payment application of the terminal device, the terminal device selects any card application of the card applications indicated by the card selection instruction as a card application to be transacted.

For example, the card selection instruction indicates that the AID is xxx1, xxx2, xxx3, respectively, and the terminal device determines that the card application is a card application a corresponding to xxx1, a card application b corresponding to xxx2, and a card application c corresponding to xxx3 according to table 1. The current default payment application of the terminal equipment is card application d, and the terminal equipment randomly sets card application a as card application to be transacted.

In yet another example, each card application corresponding to each AID indicated by the card selection instruction is not a default payment application of the terminal device, and the terminal device may determine a card application to be transacted according to the priority of the card application indicated by the card selection instruction. The card application with the highest priority may be used as the card application to be transacted. For example, the card selection instruction indicates an AID for each card application of the plurality of card applications, and each card application has a priority; thus, the terminal device can determine a card application as the card application to be transacted according to the priority of the payment application indicated by the card selection instruction. For another example, the card selection instruction indicates an AID for each of the plurality of card applications; the terminal device stores the information of the priority of each card application, so that the terminal device can determine one card application as the card application to be transacted according to the priority of the payment application indicated by the card selection instruction.

In this embodiment, the terminal device receives a card selection instruction sent by the collection device, where the card selection instruction is used to instruct multiple AIDs, and the card selection instruction is also used to instruct transaction processing; or the terminal equipment receives a card selection instruction and a transaction instruction sent by the cash register equipment, wherein the card selection instruction is used for indicating a plurality of AIDs, and the transaction instruction is used for indicating transaction processing. And the terminal equipment receives a plurality of AIDs and transaction indications at the same time. If the terminal equipment determines that each card application corresponding to each AID indicated by the card selection instruction does not exist in the AID list according to the AID list, the terminal equipment determines that each card application corresponding to each AID indicated by the card selection instruction is not a payment application, and the terminal equipment determines that the terminal equipment does not support each card application corresponding to each AID indicated by the card selection instruction. The terminal device needs to send prompt information to the user and the collection device, so as to inform the user and the collection device that the terminal device does not support each card application corresponding to each AID indicated by the card selection instruction. The card selection instruction is used for indicating the AID, the terminal equipment further determines whether card applications supported by the AID are supported according to the AID, and if each card application corresponding to each AID indicated by the card selection instruction does not exist in the AID list, the terminal equipment determines that the card application corresponding to the AID indicated by the card selection instruction is not supported, and further subsequent transaction processing cannot be completed.

Fig. 36 is a flowchart of another application processing method provided in the embodiment of the present application, where, as shown in fig. 36, the method may include:

s3601, receiving a card selection instruction sent by a cash register, wherein the card selection instruction is used for indicating application identifiers of N card applications, N is a positive integer greater than or equal to 1, and determining the card application corresponding to the application identifier indicated by the card selection instruction according to a preset application identifier list; the application identification list is used for indicating the corresponding relation between the application identification and the card application.

For example, when the terminal device approaches the collection device and the transaction needs to be completed, the collection device sends out field intensity information, and the field intensity information is a card selection instruction; the card selection instruction sent by the collection equipment carries the AID of the card application, or the card selection instruction sent by the collection equipment characterizes the AID of the card application. In this embodiment, the card selection instruction received by the terminal device indicates an AID of a card application; or, the card selection instruction received by the terminal device indicates the AID of each card application in the plurality of card applications.

S3602, if the card application corresponding to the application identifier indicated by the card selection instruction is determined to be not the current default payment application of the terminal equipment, determining the card application to be transacted according to the card application corresponding to the application identifier indicated by the card selection instruction.

Illustratively, an AID list has been pre-stored in the terminal device. The AID list includes at least one AID of the card application. The AID list may be referred to in the introduction of step S402.

And the terminal equipment determines each card application corresponding to each IAD indicated by the card selection instruction according to the AID list.

If the card selection instruction indicates the AID of one card application, the terminal device can directly determine the card application corresponding to the AID indicated by the card selection instruction as the card application to be transacted when determining that the card application corresponding to the AID indicated by the card selection instruction is not the current default payment application of the terminal device.

If the card selection instruction indicates the AID of the plurality of card applications, the terminal device selects one card application from the card applications corresponding to the AID indicated by the card selection instruction as the card application to be transacted when determining that each card application corresponding to each AID indicated by the card selection instruction is not the current default payment application of the terminal device. For example, the terminal device randomly selects one card application from the card applications corresponding to the AID indicated by the card selection instruction, and the selected card application is used as the card application to be transacted. For another example, the terminal device determines, from the card applications corresponding to the AID indicated by the card selection instruction, the card application with the highest priority among the card applications corresponding to the AID indicated by the card selection instruction as the card application to be transacted according to the priority of the card application.

S3603, carrying out transaction processing according to card application to be transacted.

The terminal device may, for example, complete the transaction process according to the card application to be transacted after determining the card application to be transacted.

In this embodiment, the terminal device receives a card selection instruction sent by the collection device, where the card selection instruction is used to indicate an application identifier; the terminal equipment can determine the card application corresponding to the application identifier indicated by the card selection instruction according to the application identifier list; when determining the card application corresponding to the application identifier indicated by the card selection instruction, the terminal equipment determines that the terminal equipment supports the card application corresponding to the application identifier indicated by the card selection instruction; and if the terminal equipment determines that the card application corresponding to the application identifier indicated by the card selection instruction is not the current default payment application, the terminal equipment needs to change the payment mode, and determines a card application to be transacted according to the card application corresponding to the application identifier indicated by the card selection instruction, and transacts according to the card application to be transacted. The terminal equipment automatically determines the card application needing to be transacted, the user does not need to manually modify the card application needing to be transacted into a default payment application in the terminal equipment, the transaction process between the terminal equipment and the collection equipment is quickened, and the user experience is improved.
