The embodiment of the application provides a processing method of an NFC card, the method is applied to electronic equipment, the electronic equipment can be various types of equipment with information processing capability in the implementation process, for example, the electronic equipment can comprise a mobile phone, a tablet computer, intelligent wearable equipment (such as an intelligent bracelet) and the like. The functions implemented by the method can be implemented by calling program code by a processor in an electronic device, and the program code can be stored in a computer storage medium.
Fig. 1 is a schematic implementation flow diagram of a processing method of an NFC card provided in an embodiment of the present application, and as shown in fig. 1, the method may include the following steps 101 to 104:
In some embodiments, the set of card reading applications may include an uninstalled card reading application and an installed card reading application in the electronic device. In other embodiments, the set of card reading applications may also include only card reading applications installed in the electronic device. That is, the electronic device may select, from the installed card reading applications, a card reading application that supports NFC cards belonging to the distribution type, thereby obtaining the set of card reading applications. For example, the electronic device may implement step 101 through step 201 and step 202 of the following embodiments.
In some embodiments, the electronic device may determine the usage heat of the card reading application according to the number of times the card reading application is downloaded, the frequency of the user using the card reading application, and/or the number of times the user reads the NFC card using the card reading application.
In other embodiments, the electronic device may further determine the usage heat of each card reading application in advance, and these information is recorded in the corresponding white list, so that when step 102 is implemented, the electronic device may directly obtain the usage heat of the card reading application from the preset white list. For example, the electronic device may implement step 102 through step 207 to step 209 of the following embodiments.
103, sorting the card reading applications in the card reading application set according to the sequence of the use heat from high to low;
and 104, displaying the sorted card reading application set for the user to select the card reading application to be used.
It is understood that the higher the usage heat of the card reading application, the more likely it is that the NFC card to be processed is correctly recognized and processed, and the more likely it is the card reading application that the user desires to use. Therefore, in the embodiment of the application, the card reading applications in the set are sorted in the order of the heat of use from high to low, so that the application with the higher heat of use is displayed more forward, and is easier to be selected by a user. Therefore, the method for processing the NFC card can improve the probability of selecting the correct card reading application by the user, so that the success rate of card reading is improved, and the use experience of the user is improved.
In practical applications, when the number of card reading applications included in the card reading application set is greater than or equal to 2, the program cannot determine to which application to distribute the data stored in the NFC card for processing, and in such a case, an application selection interface including icons of the applications is usually popped up to allow the user to select a certain application to process the NFC card. However, in general, in the face of these displayed applications, the user does not have the ability to accurately judge the processing capability of the card reading application on the read card, and eventually, the application selected by the user at a high probability cannot correctly read the read card, that is, the selected card reading application is "wrong", and the user experience is poor.
In view of this, in the embodiment of the present application, the electronic device displays the card reading applications to be selected in the order of the use heat from high to low, instead of displaying the card reading applications to be selected in the order of the initials of the application names; therefore, the probability of selecting the correct card reading application by the user is greatly improved, and the card reading success rate of the electronic equipment is correspondingly improved.
Fig. 2 is a schematic flow chart illustrating an implementation of the processing method for the NFC card provided in the embodiment of the present application, and as shown in fig. 2, the method may include the following steps 201 to 211:
In contrast to the target type obtained in step 204 below, the NFC card is actually roughly recognized here to recognize the distribution type supporting the NFC card.
It should be noted that NDEF, an abbreviation of NFC Data Exchange Format, refers to an NFC Data Exchange Format, that is, a Data Format in an NFC tag agreed by an NFC organization; the method is defined in an android native card reading distribution system as follows: and if the distribution type of the NFC card is NDEF, distributing the NFC card data according to a distribution rule corresponding to the type.
TECH, an abbreviation of Technology, refers to the hardware radio frequency Technology adopted by NFC cards, such as: TypeA, TypeB, etc.; the method is defined in an android native card reading distribution system as follows: and if the distribution type of the NFC card is TECH, distributing the NFC card data according to a distribution rule corresponding to the type.
TAG, which refers to NFC card capable of recording data; the method is defined in an android native card reading distribution system as follows: and if the distribution type of the NFC card is TAG, distributing the NFC card data according to a distribution rule corresponding to the type.
In the android native card reading distribution system, three intents (Intent) are defined, listed as follows in priority from high to low:
ACTION _ NDEF _ uncovered. If a tag containing the NDEF load is scanned and its type can be identified, this Intent is used to initiate Activity (Activity). This is the highest priority Intent, and the tag scheduling system will try to use this Intent to start Activity whenever possible, and will not try to use other intents when the line is not up.
ACTION _ TECH _ uncovered: if the Activity of the ACTION _ NDEF _ DISCOVERED Intent is not registered, the tag scheduling system will attempt to use this Intent to launch the application. Furthermore, if the scanned tag contains NDEF data that cannot be mapped to a MIME type or URI defined by an android, or the tag does not contain NDEF data, but it uses known tagging techniques, then this Intent is also directly enabled without first enabling ACTION _ NDEF _ uncovered.
ACTION _ TAG _ uncovered: if Activity of the ACTION _ NDEF _ DISCOVERED or ACTION _ TECH _ DISCOVERED Intent is not processed, then the Intent is used to initiate Activity.
It is understood that Activity is one of the four most basic and most commonly used components in Android (Android) components. In an android application, an Activity is usually a separate screen on which controls can be displayed and in which events from the user can be monitored and processed in response. Activity communicates with each other through Intent. Intent in android is a very important and commonly used class that can be used to launch another component in an application or another application in one component, where the components are referred to as Activity, Service, and Broadcast.
it is to be understood that the number of applications in the set is 0, which indicates that there is no card reading application supporting the distribution type of the NFC card in the installed applications, and step 204 may be executed.
And step 204, determining the target type of the NFC card.
In contrast to the identification of the distribution type, step 204 is actually a fine identification of the NFC card, so as to determine the target type of the NFC card. That is, the accuracy of the target type is higher than the accuracy of the distribution type.
In some embodiments, the electronic device may read data stored by the NFC card; then, analyzing the data and extracting characteristics; based on the extracted features, a specific type (i.e., target type) of the card is determined. It will be appreciated that the target type is more accurate than the distribution type.
For example, assuming that the NFC card to be processed is a bus card, the distribution type of the NFC card is identified as a TECH card through step 201, and the target type of the NFC card can be identified as a shanghai tong bus card through step 204.
As can be appreciated, since the accuracy of the target type is higher than the accuracy of the distribution type, recommending the card reading application to the user based on the target type of the card is more accurate than recommending the card reading application to the user based on the distribution type of the card. In other words, the recommended card reading application has a higher success rate of reading card data.
For example, if the NFC card to be processed is a public transportation card, only the type of the public transportation card is a TECH card through step 201, and the accuracy of the identification result is very low because the TECH is a physical characteristic existing in each card; if the card reading application supporting the card is recommended based on the TECH card, the recommended result precision is very low, and the recommended card reading application may not successfully read the data of the card; therefore, further, the electronic device performs a fine recognition of the public transportation card, for example, recognizing that the card is not only a public transportation card (distribution type), but also a "city card" (target type) of west ampere; therefore, the card reading application recommended based on the result is more accurate, and the card reading success rate is correspondingly higher.
here again the target type of the NFC card obtained by the electronic device through a fine recognition of the NFC card to be processed.
and 209, setting the use heat of the target application to be higher than the use heat of the non-target application in the card reading application set.
It can be understood that the card reading application set is a result of screening applications based on distribution types of NFC cards, and the screening is coarse, so that some of the card reading applications may not process data stored in the card. Through the steps 207 and 208 of the embodiment of the application, the card reading application set is further screened, so that the card reading applications obtained through the further screening are preferentially displayed through the steps 209 and 210, the number of applications selected by the user is reduced, the probability that the user selects the correct card reading application is further improved, and the card reading success rate can be correspondingly improved.
In some embodiments, the electronic device may implement step 208 by: acquiring a preset white list corresponding to the target type, wherein the preset white list comprises a card reading application which supports the target type and meets the requirement of use heat and the corresponding use heat; determining a target application in the preset white list in the card reading application set; accordingly, step 209 comprises: acquiring the use heat of the target application from the preset white list; the usage heat of the non-target application is set to be lower than the usage heat of each of the target applications.
For example, assume that the determined set of card reading applications includes a card reading application a, a card reading application B, a card reading application C, a card reading application D, a card reading application E, and a card reading application F based on the distribution type of the NFC card. Based on the fine identification result of the NFC card, namely the target type, obtaining a preset white list corresponding to the target type, wherein the preset white list comprises a card reading application A, a card reading application C and a card reading application D, and the use heat degrees of the three applications are respectively 80, 90 and 95; wherein, the larger the value, the higher the heat of use. The resulting heat of use for card reading applications a through F is then as shown in table 1 below:
TABLE 1
| Card reading application | Heat of use | Card reading application | Heat of use |
| Card reading application A | 80 | Card reading application D | 95 |
| Card reading application B | 0 | Card reading application E | 0 |
| Card reading application C | 90 | Card reading application F | 0 |
And step 210, sorting the card reading applications in the card reading application set according to the sequence of the use heat from high to low.
In some embodiments, the usage heat of each card reading application in the preset white list is characterized by a priority, and the usage heat is positively correlated with the priority; that is, the higher the priority, the higher the usage heat; conversely, the lower the priority, the lower the degree of use. Then, the electronic device may set the priority of the non-target application in the set of card reading applications to the lowest priority.
Accordingly, the electronic device may sort the card reading applications in the card reading application set according to the priority from high to low.
And step 211, displaying the sorted card reading application set for the user to select the card reading application to be used.
In some embodiments, the electronic device may display icons of the card reading applications in the set at the application selection interface. And when a selection instruction is received, sending the data stored in the NFC card to the selected card reading application, and performing data processing by the application.
Fig. 3 is a schematic flow chart illustrating an implementation of the processing method for the NFC card provided in the embodiment of the present application, and as shown in fig. 3, the method may include the following steps 301 to 311:
NFC cards belonging to a specific tag are also called direct class tags. And for the direct type tags, for example, the tags used for controlling the start of TV screen projection are identified, and then the data stored in the tags are directly sent to the corresponding application, so that the application can directly start the TV screen projection, and the application icons of the TV screen projection do not need to be displayed for the user to click. For another example, the bus card is a specific tag, and the corresponding designated card reading application is a certain payment application. After the data of the bus card is distributed to the payment application, the application processes the data as follows: and directly displaying a recharging interface of the bus card, wherein the interface comprises balance, user information and the like. Before the recharging interface is displayed, interfaces such as the application icon and the like which are irrelevant to the recharging interface do not need to be displayed. Therefore, the direct capability is added to the specific label, and the card reading process can be saved.
It is understood that when the NFC card to be processed is identified, it may be determined whether the card is a specific tag, and if so, the following steps 304 to 311 are not performed, but the data stored in the card is directly distributed to the card reading application bound to the card (i.e., the specified card reading application). Namely, the direct capability is added to the specific label, and the user does not need to select the direct capability, but directly jumps to the specified application; in this way, specific tags such as these private tags are not destroyed to the direct experience by malicious registration by the three-party software.
In some embodiments, the processing of the data by the designated card reading application may be implemented by a background service; therefore, some meaningless User Interfaces (UI) can be prevented from being displayed, and the User experience is improved.
the value of N may be a preset value, for example, 3 or 4, etc. In some embodiments, N is smaller than the number of applications in the card reading application set, so that the number of applications selected by the user can be reduced, the probability that the user selects the correct card reading application is higher, and the card reading success rate is correspondingly improved.
And 308, displaying a viewing button on the application selection interface, wherein the viewing button is used for controlling the application selection interface to expand the rest non-displayed card reading applications in the card reading application set.
As shown in fig. 4A, icons of the card reading applications using the top 4 of the hotness ranking, i.e., APP1 through APP4, and a view button 401 of "display more APPs" are displayed on the application selection interface 40.
As shown in fig. 4A, a prompt box 402 including "detect NFC tag, please select open application" may also be displayed on the application selection interface 40, and a "cancel" button 403 for canceling the display of the application selection interface 40 is displayed.
When the view button 401 receives a touch operation, as shown in fig. 4B, icons of APP5 to APP8 are additionally displayed on the application selection interface 40. When the user slides the interface 40 to the left, icons for other card reading applications are displayed on the other interface.
It should be noted that, generally, step 307 and step 308 are executed in parallel, that is, the top N card reading applications and the view button for controlling viewing of more applications are displayed on the application selection interface.
And 309, when detecting that the card reading application receives a selection instruction, displaying a direct setting button, wherein the direct setting button is used for controlling the electronic equipment to set the selected card reading application as a specified card reading application of the NFC card.
The user may issue the selection instruction in various ways. For example, the user may issue a selection instruction in a voice control mode, a touch control mode, or the like, where the selection instruction is used to instruct selection of a corresponding card reading application to process data stored in the NFC card.
The android native card reading distribution process is distributed step by step according to NDEF, TECH and TAG, the distribution precision is gradually reduced, and the distribution process is shown in FIG. 5, namely: if a label in NDEF format (i.e., an NFC card) is scanned, then Activity is started using Intent "NDEF _ DISCOVERED"; at this point, it is determined whether "NDEF _ uncovered" can be processed by registered Activity; if so, passing the Intent to Activity; otherwise, the scanned tag is considered to be a tag in an unmapped or non-NDEF format, and the Intent of "TECH _ uncovered" is used to start Activity; at this point, it is determined whether "TECH _ DISCOVERED" can be processed by registered Activity; if so, passing the Intent to Activity; otherwise, using Intent of "TAG _ DISCOVERED" to start Activity; at this point it is determined whether "TAG _ DISCOVERED" can be processed by registered Activity; if so, passing the Intent to Activity; otherwise, ending, declaring card reading failure.
If a collision occurs during distribution (i.e., multiple card reading applications are matched), an application selection box needs to be popped up to allow the user to select an application to process the card reading event, for example, as shown in fig. 6. The related distribution technology has several problems:
1. the distribution accuracy is low. Except for the high accuracy of NDEF types, the accuracy of both the TECH type and the TAG type is too low, because the TECH is a physical characteristic of each card, and the variety is small, the specific card type cannot be judged by the TECH, and the accuracy of the TAG type is the lowest, and the TAG type does not contain any characteristics of the card at all.
However, the low distribution accuracy may cause a high probability of collision during distribution, that is, a plurality of applications register reading of the same type of cards, and a program cannot determine which application to distribute a tag to process the tag, in this case, a selection box needs to be popped up to allow a user to select a card reading application that can be processed, but a general user does not have the ability to accurately judge the processing capability of the card reading application on a card to be read, and finally, an application selected by the user at a high probability after reading the card cannot correctly read the read card, and the user experience is poor;
2. the card reading application is fixed in arrangement order. The native application selection interface (UI), the applications are ordered according to names, if the applications that the user wants to use are ordered, the user needs to turn to the last to select the desired application each time, and the user experience is poor.
Based on this, an exemplary application of the embodiment of the present application in a practical application scenario will be described below.
In the embodiment of the application, more feature extractions are added in the NFC service during card reading, types are assigned to cards meeting certain features, existing card reading applications in the market are screened according to the types, a white list [ card class-card reading application ] is established, the white list simultaneously records a preset priority of each card reading application, a native distribution result is enhanced according to a mapping relation of the white list during distribution, and the overall flow is shown in fig. 7. The detailed steps are as follows:
step 1, establishing models for some common NFC cards on the market to extract features, digitizing the models, defining the models as [ rules ], endowing the cards conforming to the rules with one type, wherein each rule has one and only can uniquely determine one card type;
step 2, when reading the NFC card, the NFC service traverses all rules to identify, and binds a type for the label after the identification is successful, which corresponds to the sequence number 1 in the figure 7;
and 3, after the identification is finished, distributing the labels according to a native distribution flow, namely distributing the NDEF, the TECH and the TAG. Number 2 corresponding to fig. 7;
and 4, directly distributing to the matched application according to the native flow if no collision occurs (namely, only the single card reading application is matched) during distribution, and finishing the distribution. Corresponding to the sequence number 3 through sequence number 8 in fig. 7;
step 5, if collision occurs in the distribution process (namely, a plurality of matched card reading applications exist), judging whether the applications in the list exist in a white list of the cards; if the list exists, the priorities in the white list are selected for sorting (corresponding to the sequence number 5 in fig. 7), and the list is displayed to the user for selection through the UI (corresponding to the sequence number 6 in fig. 7) after being sorted. Meanwhile, the UI guides the user to select the application with the highest priority, only a few applications with the highest priority are displayed in a pop-up selection frame by default, and other applications are hidden by default; clicking the "show more applications" button opens the selection of other applications.
Step 6, if a certain card can determine that only one application can process, such as a private label, the application can be given the highest priority to the card of the type, and when the card of the type is read, the card is directly distributed to the application regardless of the original distribution result, namely, the card is directly distributed to the application, namely, the card is directly distributed to the rule. Corresponding to the sequence number 4 through sequence number 8 in fig. 7;
and 7: besides the preset priority, the priority of the application commonly used by the user can be increased by learning the use habit of the user, so that the application commonly used by the user can be selected more easily. The prioritization here is also done in the sequence 5 step in fig. 7;
and 8: for rule distribution of direct classes, pull Service may be supported instead of Activity.
It is understood that Service is one of the four major components in the android system, called "background Service", meaning that its own operation does not rely on a UI interface visible to the user. Activity is the core concept of android applications, in short, Activity is a user interaction manager and has a visual interface presentation, and Service differs from Activity in that it runs in the background and has no interface presentation.
The beneficial effects brought by the embodiment of the application have the following points:
1. the probability of successful card reading of the user is improved. By improving the card identification and distribution precision, screened applications are preferentially displayed, the number of applications needing to be selected by a user is reduced, the probability that the user selects the correct card reading application is greatly improved, the card reading success rate is correspondingly improved, and the card reading experience of the user is improved;
2. specific tags are supported to be directed. Direct capability is added for a specific label, a user does not need to select to directly jump to a specified application, and some private labels cannot be maliciously registered by three-party software to damage direct experience;
3. the user learns using habits. By learning the use habit of the card reading application of the user, the user can more conveniently select the application which the user wants to use;
4. the Service can be pulled up. The native distribution can only support pull-up Activity, so that the use is limited, and through expansion, the pull-up Service support is added for the direct type card distribution, so that the use scene is enriched.
It can be understood that in the embodiment of the application, the card reading applications are screened in advance, the card reading applications are associated with the supported card types, the cards are accurately identified during card reading, the card reading applications are matched according to the card types in the distribution process, and finally the application selection UI is enhanced by using the matching result, so that a user is guided to select the correct card reading application, and the card reading success rate is improved.
In some embodiments, an option of processing the card by using the application all the time is added to the application selection UI, and the recorded application is directly used for card reading after the card is read next time, so that the selection times of a user are reduced;
in some embodiments, when a known type of card is read, but a supported card reading application is not installed in the mobile phone, an application recommendation interface pops up, and a user is guided to go to an application store to download the recommended card reading application.
