In the related art, an electronic device supporting a near field communication function generally installs a plurality of NFC analog cards, such as a bank card, an access control card, a traffic card, and the like, and when a card is swiped, the device uses a default NFC analog card to interact, and if other NFC analog cards are to be used, a user is usually required to manually select the card on a display interface of the electronic device, which takes a long time, and affects the card swiping efficiency and experience. Therefore, in order to improve the card swiping efficiency, a card swiping scheme for selecting an NFC analog card based on a geographic position is provided, however, the accuracy for selecting the NFC analog card through the geographic position is not high, for example, the geographic position where a traffic card is applicable is not fixed and is wide, and in this scenario, the situation that a correct NFC analog card cannot be matched easily occurs, so that the NFC analog card cannot be accurately matched.

The following describes the near field communication interaction architecture in the embodiment of the present application in detail with reference to fig. 1.

As shown in fig. 1, the architecture system of the near field communication interaction method may include a user terminal 11 and a card swiping terminal 12.

The user terminal 11 is a terminal device with an NFC analog card, and may specifically include a mobile phone, a tablet computer, an intelligent wearable device, etc., and the specific type of the user terminal 11 is not limited herein. The user terminal 11 supports a card mode, which is to simulate the electronic device with NFC function into a contactless radio frequency card conforming to the NFC related standard, where the contactless radio frequency card is an NFC analog card, and the user terminal 11 can perform NFC communication interaction and data interaction with the swipe card terminal 12 by using the NFC analog card. The user terminal 11 may be provided with an NFC management application for managing an NFC emulated card, where the NFC emulated card may be displayed on an application interface of the NFC management application in the form of an electronic card, and when a user needs to use a certain NFC emulated card, the user may directly open the NFC emulated card in the NFC management application, and approach the user terminal 11 to the card swiping terminal 12 to swipe the card or swipe the card.

The card swiping terminal 12 is a card swiping device, i.e., a card reader, for reading NFC tags. The card swiping terminal 12 can be used as a card swiping device to perform NFC communication interaction with the user terminal 11, and read an NFC analog card in the user terminal 11.

Based on the payment architecture provided by the embodiment of the present application shown in fig. 1, the near field communication interaction method provided by the embodiment of the present application is described in detail.

The first aspect of the present application provides a near field communication interaction method, which is applicable to a user terminal, i.e. the near field communication interaction method is executable by the user terminal. The details of the user terminal may be referred to the related descriptions in the above embodiments, and will not be described herein.

Fig. 2 is a flowchart of an embodiment of a near field communication interaction method according to the first aspect of the present application. As shown in fig. 2, the near field communication interaction method may include steps 210-250.

Step 210, obtaining a scene message broadcasted by a card swiping terminal;

step 220, analyzing the scene message to obtain a target scene identifier of the scene where the card swiping terminal is located;

step 230, under the condition that the NFC radio frequency signal is detected, the NFC management application is called up, and a target NFC analog card matched with the target scene identification is selected from a plurality of NFC analog cards through the NFC management application;

Step 240, determining the current NFC communication object of the user terminal as a target NFC emulated card;

and step 250, performing near field communication interaction with the card swiping terminal through the target NFC analog card.

According to the near field communication interaction method provided by the embodiment of the application, the scene message broadcasted by the card swiping terminal can be obtained under the scene where the user terminal is located, and the target scene identification of the scene where the card swiping terminal is located can be obtained by analyzing the scene message. Based on the above, under the condition that the user terminal detects the NFC radio frequency signal, the NFC management application can select a target NFC analog card matched with the target scene identifier from a plurality of installed NFC analog cards according to the target scene identifier, so that the quick matching of the NFC analog cards is realized for the scene where the card swiping terminal is located, namely, the current scene is matched with the correct NFC analog card. Therefore, the current NFC communication object of the user terminal is confirmed to be the target NFC analog card, accurate selection of the NFC analog card can be achieved, near field communication interaction with the card swiping terminal can be successfully completed through the correct target NFC analog card, the situation that the NFC analog card cannot be matched to the correct NFC analog card is avoided, and the matching accuracy and the card swiping success rate of the NFC analog card are improved.

The following describes the specific implementation of the above steps in detail with reference to examples, and is specifically shown below.

Involves step 210 of obtaining a scene message broadcast by the swipe terminal.

In step 210, the card swiping terminal may broadcast the scene message through a preset broadcasting method, which may include, but is not limited to: bluetooth, wireless communication technology WIFI, wireless carrier communication technology (UWB), radio frequency identification (Radio Frequency Identification, RFID) technology; correspondingly, the user terminal can acquire the scene message in the same information acquisition mode as the preset broadcasting mode.

Step 220 is involved, the scene message is parsed, and the target scene identifier of the scene where the card swiping terminal is located is obtained.

In step 220, the scene message may carry a scene identifier of the scene in which the card swiping terminal is located, that is, a target scene identifier, and the scene message broadcast by the card swiping terminal is different based on the difference of the scenes in which the card swiping terminal is located.

For an access card swiping terminal, in a scene message broadcast by an access card swiping terminal in a 'company' scene, the carried target scene is identified as a 'company-access', and in a scene message broadcast by an access card swiping terminal in a 'home' scene, the carried target scene is identified as a 'home-access'.

In some embodiments of the present application, the scene identifier may be stored in a payload of the scene message, so that the user terminal may obtain the target scene identifier carried in the scene message by parsing the payload of the scene message.

In some embodiments of the application, the scene identification may be determined using standard codes or naming rules.

Step 230 is involved, in the case of detecting the NFC radio frequency signal, invoking the NFC management application, and selecting, by the NFC management application, a target NFC emulated card from the plurality of NFC emulated cards that matches the target scene identifier.

In step 230, when the user terminal approaches the card swiping terminal, the card swiping operation is started, and at this time, the user terminal may sense an NFC radio frequency signal emitted by the card swiping terminal, where the NFC radio frequency signal is used to read an NFC analog card in the user terminal. Therefore, when the NFC radio frequency signal is detected, the user terminal starts an NFC management application, where the NFC management application is configured to manage NFC analog cards, where the NFC management application includes a plurality of NFC analog cards, where the plurality of NFC analog cards may be integrated on the NFC management application, where the NFC management application may be, for example, a wallet application, and where the NFC management application may be called by the NFC controller, and after being called, the NFC management application may select, from the plurality of NFC analog cards, a target NFC analog card matching the target scene identifier for performing NFC communication interaction with the card swiping terminal.

It should be noted that the execution sequence of the steps 210, 220, 230 is not specifically limited in the present application, and the step 210 may be before the step 230 or after the step 230.

In other embodiments of the application, the method may include: invoking an NFC management application upon detecting an NFC radio frequency signal; acquiring a scene message broadcasted by a card swiping terminal; analyzing the scene information to obtain a target scene identifier of the scene where the card swiping terminal is located; and selecting a target NFC simulation card matched with the target scene identifier from the plurality of NFC simulation cards through the NFC management application.

In still other embodiments of the present application, the method may include: the NFC management application is called up under the condition that a scene message broadcasted by the card swiping terminal is acquired; analyzing the scene message through the NFC management application to obtain a target scene identifier of the scene where the card swiping terminal is located; and under the condition that the NFC radio frequency signal is detected, selecting a target NFC analog card matched with the target scene identification from a plurality of NFC analog cards through the NFC management application.

In some embodiments of the present application, in order to ensure the scene suitability of the selected target NFC emulated card and the card swiping terminal, fig. 3 is a flowchart of another embodiment of the near field communication interaction method provided in the first aspect of the present application, and step 210 may be preceded by steps 310 to 330 shown in fig. 3.

Step 310, acquiring scene types associated with a plurality of NFC analog cards;

step 320, dividing the NFC emulated cards associated with the same scene type into the same scene group to obtain a plurality of scene groups;

step 330, setting corresponding packet identifications for a plurality of scene packets based on scene types associated with the NFC emulated card in the scene packets.

For example, the plurality of NFC emulated cards may include card a, card B, card C, and card D, wherein the scene types associated with card a and card B are each a "consumption-bank card", the scene type associated with card C is a "traffic-bus card", and the scene type associated with card D is a "home-entrance guard" so that card a, card B, card C, and card D are respectively divided into three groups.

In the embodiment of the application, by dividing the NFC analog cards associated with the same scene type into the same scene group in advance, one scene group can be allocated to each scene. In this way, under different scenes, by selecting the target NFC analog card from the scene group adapted to the target NFC analog card, the adaptation of the selected target NFC analog card and the scene where the card swiping terminal is located can be ensured, and therefore the correctness of the NFC analog card read by the card swiping terminal is ensured.

In other embodiments of the present application, the user terminal may display an application interface of the NFC management application, and group the plurality of NFC emulated cards by receiving a user input at the application interface, and set a corresponding group identifier.

In some embodiments of the present application, in order to improve accuracy of screening correct NFC analog cards from multiple NFC analog cards, fig. 4 is a flowchart of still another embodiment of a near field communication interaction method provided in the first aspect of the present application, and step 230 of selecting, by an NFC management application, a target NFC analog card matching a target scene identifier from multiple NFC analog cards may include steps 410 to 430 shown in fig. 4.

Step 410, through the NFC management application, selecting a target scene packet with a packet identifier consistent with the target scene identifier from the plurality of scene packets;

step 420, determining, by the NFC management application, that the unique NFC emulated card is the target NFC emulated card if the unique NFC emulated card exists in the target scenario packet;

in step 430, in the case that the number of NFC emulated cards in the target scenario packet is greater than 1, the NFC emulated card with the highest priority in the target scenario packet is determined to be the target NFC emulated card by the NFC management application.

In the embodiment of the application, the target scene group matched with the scene where the card swiping terminal is located can be screened by comparing the group identifier with the target scene identifier, and when only one NFC analog card exists in the target scene group, the NFC management application can directly take the NFC analog card as the target NFC analog card; when the target scene group contains two or more NFC simulation cards, the accuracy of screening correct NFC simulation cards from the NFC simulation cards can be improved by setting the NFC simulation card with the highest priority as the target NFC simulation card.

In some embodiments of the application, the priority may be determined based on one or more of user settings, geographic location, user behavior habit data.

The user may set the priority of the NFC emulated card by himself, for example, set the priority order of the plurality of NFC emulated cards, or set a certain NFC emulated card as a default NFC emulated card, so that the priority of the default NFC emulated card is higher than that of other NFC emulated cards that are not set as defaults. Each NFC emulated card may be associated with a piece of geographic location information, the closer the geographic location information is to the address location information of the swipe terminal, the higher the similarity of the NFC emulated card. The user behavior habit data may include user card swiping behavior data, where the user card swiping behavior data includes information such as card type, card swiping success or failure, card swiping time of the user using the NFC analog card, and the information may be obtained by an application program on the user terminal or a call log.

In the related art, when detecting an NFC radio frequency signal, a user terminal invokes an NFC management application, and in a scenario in which the user terminal is provided with a default NFC analog card, the NFC management application directly reads the default NFC analog card, and performs NFC communication interaction with a card swiping terminal by using the default NFC analog card as a current NFC communication object. In this way, when the default NFC analog card is not matched with the scene where the current card swiping terminal is located, for example, the default NFC analog card is an access control card, and the card swiping terminal is a gate of a subway station, the card swiping failure will occur.

In some embodiments of the present application, the plurality of NFC emulated cards include a default NFC emulated card, and in order to avoid a card swiping failure in the related art, fig. 5 is a flowchart of still another embodiment of a near field communication interaction method provided in the first aspect of the present application, and step 230 may include steps 510 to 540 shown in fig. 5.

Step 510, receiving, by the NFC controller, NFC application interaction data sent by the card swiping terminal and invoking an NFC management application, in the case of detecting an NFC radio frequency signal;

step 520, forwarding, by the NFC controller, the NFC application interaction data to the NFC management application, so that the NFC management application obtains a packet identifier of the default NFC emulated card and compares the packet identifier of the default NFC emulated card with the target scene identifier when receiving the NFC application interaction data;

step 530, determining, by the NFC management application, that the target NFC emulated card is a default NFC emulated card, and directly forwarding NFC application interaction data to a card application of the default NFC emulated card, if the packet identifier matches the target scene identifier;

step 540, in the case that the packet identifier does not match with the target scene identifier, the NFC management application is configured to screen the target scene packet with the packet identifier consistent with the target scene identifier from the plurality of scene packets, and directly forward the NFC application interaction data to the card application of the target NFC analog card in the target scene packet.

Specifically, the NFC controller may be an NFC control chip. The NFC application interaction data are used for the user terminal to conduct near field communication interaction through the NFC analog card and the card swiping terminal according to application specifications, wherein the application specifications are specifications of card applications of the NFC analog card.

For example, in a scenario where the NFC emulated card is a financial IC card, the application specification may be a PBOC specification, where the PBOC specification includes standard interaction instructions such as PPSE.

In the embodiment of the application, when receiving the NFC application interaction data sent by the card swiping terminal, the NFC controller does not directly send the NFC application interaction data to the card application of the default NFC analog card, but sends the NFC application interaction data to the NFC management application, and the NFC management application forwards the data. Based on the method, the NFC management application can acquire the grouping identification of the default NFC analog card and compare the grouping identification with the target scene identification before forwarding the data, so that the NFC application interaction data can be directly forwarded to the card application of the default NFC analog card under the condition that the grouping identification is matched with the target scene identification; or under the condition that the grouping identification is not matched with the target scene identification, the NFC management application screens the target scene grouping with the grouping identification consistent with the target scene identification from the plurality of scene groupings, and directly forwards NFC application interaction data to the card application of the target NFC analog card in the target scene grouping. Therefore, when NFC communication interaction between the default NFC analog card and the card swiping terminal is carried out, the NFC management application can avoid the situation that card swiping fails due to mismatching of scenes where the default NFC analog card and the card swiping terminal are located, and the reliability of NFC card swiping is improved.

In some embodiments of the present application, the plurality of NFC emulated cards include default NFC emulated cards, and in order to switch to a correct NFC emulated card in time after the card swiping failure in the related art occurs, fig. 6 is a flowchart of still another embodiment of the near field communication interaction method provided in the first aspect of the present application, and step 230 may include steps 610 to 640 shown in fig. 6.

Step 610, receiving, by the NFC controller, NFC application interaction data sent by the card swiping terminal and invoking an NFC management application, in the case of detecting an NFC radio frequency signal;

step 620, forwarding the NFC application interaction data directly to the card application of the default NFC emulated card through the NFC controller, and determining that the current NFC communication object of the user terminal is the default NFC emulated card;

step 630, receiving a card swiping failure message sent by a card swiping terminal under the condition that the group identifier of the default NFC analog card is not matched with the target scene identifier;

in step 640, in the case of detecting the NFC radio frequency signal again, the NFC management application is used to screen the target scenario packet with the packet identifier consistent with the target scenario identifier from the multiple scenario packets, and directly forward the NFC application interaction data to the card application of the target NFC analog card in the target scenario packet.

The NFC application interaction data are used for near field communication interaction between the user terminal and the card swiping terminal through the NFC analog card according to application specifications.

In the embodiment of the application, when receiving the NFC application interaction data sent by the card swiping terminal, the NFC controller directly sends the NFC application interaction data to the card application of the default NFC analog card, so that the user terminal performs NFC communication interaction with the card swiping terminal through the default NFC analog card, and card swiping failure is caused when the scene where the default NFC analog card and the card swiping terminal are located is not matched. On the basis, after receiving the card swiping failure message, when the user holds the user terminal by hand and releases the card swiping terminal again to perform card swiping operation, the user terminal can sense the NFC radio frequency signal again, further screen target scene groups with the group identification consistent with the target scene identification through the NFC management application, and directly forward NFC application interaction data to card applications of target NFC simulation cards in the target scene groups, so that the user terminal can be switched to the target NFC simulation cards matched with the card swiping terminal in time, namely correct NFC simulation cards, and the follow-up card swiping operation is ensured to be performed smoothly.

It should be noted that, after the NFC management application screens out the target scenario packet in step 540 and step 640, the schemes corresponding to step 420 and step 430 may be adopted to select the target NFC analog card from the target scenario packet, which is not described herein for brevity.

Step 240 is involved in determining that the current NFC communication object of the user terminal is the target NFC emulated card.

In step 240, although the user terminal includes a plurality of NFC emulated cards, at the same time, only one NFC emulated card exists as a current NFC communication object to perform NFC communication interaction with the card swiping terminal.

In some embodiments of the present application, after the step 640, determining that the current NFC communication object of the user terminal is the target NFC emulated card may specifically include:

and switching the current NFC communication object of the user terminal from the default NFC analog card to the target NFC analog card.

In the embodiment of the application, if the user terminal fails to swipe the card through the default NFC analog card for the first time, the current NFC communication object can be switched to the correct target NFC analog card by calling the NFC management application, so that the follow-up card swiping operation is ensured to be smoothly carried out.

Involves step 250 of performing near field communication interaction with the swipe terminal through the target NFC emulated card.

In step 250, the user terminal uses the target NFC emulated card to interact with the card swiping terminal for NFC command, thereby completing the whole card swiping process.

The second aspect of the present application provides a near field communication interaction method, which can be applied to a card swiping terminal, that is, the near field communication interaction method can be executed by the card swiping terminal. The details of the card swiping terminal can be referred to the related descriptions in the above embodiments, and will not be repeated here.

Fig. 7 is a flowchart of an embodiment of a near field communication interaction method according to the second aspect of the present application. As shown in fig. 7, the near field communication interaction method may include steps 710-730.

Step 710, generating a scene message based on a target scene identifier of a scene where the card swiping terminal is located;

step 720, broadcasting a scene message in a preset broadcasting mode, wherein the scene message is used for indicating the user terminal to switch the current NFC communication object into a target NFC analog card matched with the target scene identifier;

and step 730, performing near field communication interaction with the target NFC analog card in the user terminal.
