It is driven by non-contact radio frequency identification and interconnection. Evolved from technology integration, by integrating the functions of inductive card readers, inductive cards and point-to-point communication on a single chip, electronic devices are used to realize mobile payment, electronic ticketing, access control, mobile identity recognition, anti-counterfeiting and other applications.

As more and more public terminals support NFC functions, one electronic device can support users to set multiple NFC cards. In order to facilitate users to use cards, electronic devices adopt automatic card selection technology. The existing automatic card selection technology is based on Electronic device base station positioning is used to assist automatic card selection, but the accuracy is low.

In view of this, embodiments of the present application provide a method for selecting a near field communication card by obtaining the first information of the electronic device, where the first information is the current location information and/or the collected current card reader information. , the current location information includes at least one of current GPS fingerprint information and current WIFI fingerprint information, and the current card reader information includes at least one of current card reader card search characteristics and current card reader application identifier ; Determine the first NFC card based on the first information and the preset corresponding relationship. This method greatly improves the success rate and accuracy of intelligent card selection.

The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

Figure 1 is a schematic flowchart of the implementation of a near field communication card selection method provided by an embodiment of the present application. This method can be applied to electronic devices. During the implementation process, the electronic devices can be various types of devices with information processing capabilities. equipment. For example, the electronic device may include a personal computer, a notebook computer, a palmtop computer, or a server; the electronic device may also be a mobile terminal. For example, the mobile terminal may include a mobile phone, a vehicle-mounted computer, a tablet computer, or a projector. As shown in Figure 1, the method may include the following steps 101 to 102:

Step 101: Obtain the first information of the electronic device. The first information is the current location information and/or the collected current card reader information. The current location information includes the current GPS fingerprint information and the current WIFI fingerprint information. At least one of the current card reader information includes at least one of the current card reader card search feature and the current card reader application identifier.

It should be noted that the electronic device can be an electronic device with GPS positioning function and WIFI wireless communication function. In order to perform intelligent card selection, the electronic device first obtains first information. The first information may be current location information, collected current card reader information, or include both current location information and collected current card reader information. Among them, the current location information can be the current GPS fingerprint information, the current WIFI fingerprint information, or include both the current GPS fingerprint information and the current WIFI fingerprint information. The current card reader information can be the current card reader card finding characteristics and the current card reader application. Identifier, or include both the current card reader card search characteristics and the current card reader application identifier.

Among them, the GPS fingerprint information is the GPS positioning information obtained through the GPS module, the WIFI fingerprint information is the WIFI positioning information obtained through the WIFI module, and the "location fingerprint information" links the location in the actual environment with a certain "fingerprint" , one location corresponds to a unique fingerprint. This fingerprint can be single-dimensional or multi-dimensional. For example, if the device to be located is receiving or sending information, then the fingerprint can be one or more features of the information or signal. The most common feature is signal strength. The card reader's card search characteristics can be the signal characteristics of the card reader that transmits radio frequency signals to search for the card, such as the characteristics of transmitting NFC signals, polling mode polling characteristics, and the card reader application identifier refers to the card reader's support for reading. The unique identifier corresponding to the NFC card application.

Step 102: Determine the first NFC card according to the first information and the preset correspondence relationship; wherein, if the first information is the current location information, the preset correspondence relationship is the fence area corresponding to the location information and The corresponding relationship of the NFC card; if the first information is the current card reader information, the preset corresponding relationship is the corresponding relationship of the card reader information and the NFC card; if the first information is the current location information and the Describing the current card reader information, the preset corresponding relationship is the corresponding relationship between the fence area corresponding to the location information, the card reader information and the NFC card.

It should be noted that the electronic device can be preset with a corresponding relationship, and the corresponding relationship can be generated by collecting relevant information after the electronic device swipes the NFC card for the first time. If the first information is the current location information, the preset correspondence is the correspondence between the fence area corresponding to the location information and the NFC card; if the first information is the current card reader information, the preset correspondence is read The correspondence between the card reader information and the NFC card; if the first information is the current location information and the current card reader information, the preset correspondence is the correspondence between the fence area corresponding to the location information, the card reader information and the NFC card . After obtaining the first information and the corresponding relationship, the first NFC card can be determined, thereby switching the current NFC card to the first NFC, achieving the purpose of automatically selecting and cutting cards.

It can be understood that the method of determining the NFC card based on the current location information can be the pre-selected card method of this solution, and the method of determining the NFC card based on the card reader information can be the real-time card selection method of this solution. Since both the current location information and the current card reader information have obvious characteristics and can determine the current card swiping scene, smart card selection based on these two types of information greatly improves the success rate and accuracy of smart card selection, and improves user experience.

Figure 2 is a system framework diagram of an NFC card selection method provided by an embodiment of the present application. As shown in Figure 2, the system framework diagram includes a wallet module and an NFC module. The wallet module: receives the card cut notification event output by the NFC module, and displays the page during and after the transaction is completed. NFC module: includes pre-selected card sub-module and real-time card selection sub-module: 1), pre-selected card sub-module includes card selection strategy, card management, fingerprint management library, NFCEngine state machine management, signal perception, positioning strategy, fence strategy module; input includes card swiping end Events, wallet add/delete card notification events, sensor Sensor signals, the output is pre-selected card notification events; 2), real-time card selection sub-module includes real-time collection of card reader features, feature value management strategy, real-time card selection, and card reader feature library , the input is the card swiping event, and the output is the real-time card selection notification event. After receiving the card swiping event, this sub-module collects the card reader characteristics in real time, performs real-time card selection based on the card reader characteristics and the application identifier AID, and notifies the wallet of the card selection event; after the card swiping is completed, it notifies the pre-selected card of the card swiping end event. module. GPS/WIFI/Sensors provide corresponding events; the card swipe event is the recognition of the card reader field strength event; the offline collection of card reader characteristics is aimed at the characteristic collection of known typical types of card readers, such as security gates that emit NFC signals, PC, car charger with NFC function; card reader AID offline collection: it collects and summarizes the currently known AID information of bus/subway card readers and bank POS machines. Among them, Sensors can be the gravity sensor, gyroscope, etc. of a mobile phone. GPS positioning uses the gravity sensor/gyroscope to calculate longitude and latitude information, floor height, etc.

In some embodiments, the first information includes current location information. Determining the first NFC card based on the first information and a preset corresponding relationship may include: determining whether the current location information is located in the first NFC card. Within the fence area, the first fence area is the GPS fence area or WIFI fence area included in the preset correspondence relationship; if the current location information is located in the first fence area, according to the preset The corresponding relationship determines that the NFC card corresponding to the first fence area is the first NFC card.

It should be noted that the trigger conditions (input) of the pre-selected card: fence trigger event and access card swipe event; output: after the fence event is triggered, the pre-selected card is completed according to the card selection algorithm, and the selected card is activated, and the wallet is notified of the pre-selected card result. Module; after the access control card swiping event is triggered, the fence is established according to the fence policy and the fingerprint database is updated; card selection logic: the corresponding card is selected according to the fingerprint database. The initial geofence setting is triggered by the access control card swiping event. The location information and WIFI fingerprint information of the card swiping point are recorded, associated with the card ID, and saved to the fingerprint & fence library; library refresh: based on the location and fingerprint collected from the latest access control card swiping event. Refresh the database.

In some embodiments, the method may further include: if the current location information is not located within the first fence area, determining that the first NFC card is a preset NFC card.

It should be noted that cards include access control cards and transportation cards. Fence triggering is mainly used to switch access control cards, because the geographical location of the user's access control card, such as home and company, is fixed, but when swiping a transportation card, it is not a fixed location, but a second choice. This process can ensure that the access control cards at work and home can be switched correctly, and it will automatically switch to the transportation card in other scenarios.

Among them, the scope of application of geofence pre-cut cards: it is suitable for fixed card swiping positions, and the swiping positions of different cards are far apart. Limitations of geofence pre-cut cards: Scenarios where the card swiping location is not fixed, such as: digital car keys, bank cards, eIDs; card swiping locations are close to each other, such as: the user's unit building elevator and the user's home access control; the user's home access control and are close to each other public transportation card points. Advantages of geofence pre-cut cards: After the card is pre-cut successfully, users do not need to switch cards when swiping their cards, which saves the time of deactivation, activation and card cutting, and shortens the time of card swiping. Disadvantages of geofence pre-cut cards: GPS/WIFI, etc. need to be used for auxiliary positioning, which increases system power consumption.

In some embodiments, the first information includes current card reader information. Before obtaining the first information of the electronic device, the method may further include: detecting whether the signal strength of the NFC signal of the card reader is Greater than a preset strength threshold; the obtaining the first information of the electronic device includes: collecting the current card reader information of the card reader when the signal strength is greater than the preset strength threshold.

It should be noted that the trigger condition (input) for real-time card selection: card swipe event, detection of external NFC field strength (Field On). Output: According to the real-time card selection algorithm, switch to the correct card, activate the card, and notify the wallet module; if the access card is selected, the notification information is sent to the geofence module to establish the fence or refresh the fence library; select the card Logic: Real-time card selection based on card reader polling mode Polling characteristics and card reader AID characteristics. Library management: The card reader AID library needs to be collected offline in advance and associated with the corresponding card type; the card reader Polling feature library is divided into offline collection and real-time collection. Offline collection collects in advance for known typical card readers and real-time collection. The collection is collected during the process of the user swiping the card; after the card swiping is successful, the real-time collection database is updated; card reader Polling characteristics: command type, event timing (including command sequence, event interval time), and event number.

In some embodiments, the current card reader information includes the current card reader application identifier. Before collecting the current card reader information of the card reader, the method may further include: setting the current card reader application identifier. The chip type parameter of the NFC card is a preset parameter value, so that the card reader reports the current card reader application identifier.

It should be noted that the real-time card cutting time optimization currently takes about 2 seconds to switch the access card to the traffic card in real time. The access card sak=28 is set by default, so that the access card can be reported to aid by default at the traffic POS, reducing the time for temporary cutting of sak and waiting for aid to be reported. It can be optimized to about 1.6s. SAK is a default configuration parameter of the card. During the interaction with the card reader, the card will send this SAK to the card reader. The card reader can determine the next step according to the SAK. Generally, the SAK for transportation cards is 28, and for access control cards. 08 is more common. If the 08 access card is close to the subway gate, the gate will not issue a card selection instruction (aid). If you change the Sak of the access card to 28, the gate will issue a card selection instruction (aid). Mobile phone You can match and switch to the appropriate transportation card based on aid.

In some embodiments, the first information includes the collected current card reader information, and determining the first NFC card based on the first information and a preset correspondence may include: determining the Whether the current card reader information matches the first card reader information, which is the card reader card search feature or the card reader application identifier included in the preset correspondence relationship; if The current card reader information matches the first card reader information, and the NFC card corresponding to the first card reader information is determined to be the first NFC card according to the preset correspondence relationship.

It should be noted that the scope of application of real-time card cutting is: applicable to card readers with different behavioral characteristics, including different behavioral characteristics of 14443-3 and -4 layer AID (if any). Limitations of real-time card cutting: card readers with the same behavioral characteristics, such as the same model of card readers, or card readers with different models but using the same chip; card readers with highly similar behavioral characteristics, such as the same command sequence , and the command time interval is less than the card reader's limit detection capability of the mobile phone chip; the advantage of real-time card cutting: it is not restricted by the geographical location of the card reader, and there is no additional increase in power consumption. Disadvantages of real-time card cutting: During the card swiping process, card reader feature recognition, card matching, card activation/deactivation, card cutting, and card swiping actions need to be completed, which will increase the time overhead in the card swiping process.

The following is a detailed introduction to the implementation of pre-selected cards and real-time card selection.

Figure 3 is a framework diagram of a card pre-selection method provided by the embodiment of the present application. As shown in Figure 3, the key processes of card pre-selection include: 1. Card management: wallet events (swipe card/leave interface/add card/delete card/cut card ) to obtain card information. 2 Fingerprint database management: fingerprint database design (format content/storage/update learning/deletion); fingerprint collection/update/aging design; fingerprint similarity algorithm; fingerprint retrieval/matching algorithm. 3 Fence strategy: dynamic fence update; access card fence design (large fence + small fence); fence distribution. 4 Pre-selected card strategy: Card selection strategy (fence event + location + WIFI similarity); notification to cut cards. 5NfCEngine engine state machine management: fence wake-up design (AlarmManager); 1). GPS+Network positioning design; 2). Indoor and outdoor detection; 3). Stationary motion detection; signal/status awareness: 1). Location monitoring, jumping Point filtering; 2). WIFI connection/interruption, WIFIscan, WIFI similarity; 3). CELL assisted update positioning of cell information of cellular network.

For card management, including wallet events: 1. The user swipes the card, 2. The user leaves the card swiping interface, 3. The user adds a new card, 4. The user deletes the card. Card information includes: 1. Card identification number ID - application identifier AID, user identity certificate UID; 2. Card type: access control card, transportation card; 3. Current default card: application identifier AID, type type; 4 .Number of cards: number of access control cards, number of transportation cards.

The NFCEngine state machine is responsible for controlling the fence state FenceState: 0: Fence service is turned off FENCE_SERVICE_OFF, 1: Fence service is turned on FENCE_SERVICE_ON. When an NFC event (add/delete/swipe card) occurs, the fence service is turned off. Strategy: 1. Event trigger, 2. Fingerprint collection; when 1. Wallet cards ≥ 2, or valid fingerprints > 0, the fence service is turned on. Strategy: 1. Location validity period (screen on: 5 minutes, screen off: 10 minutes), wake up in 2.30 minutes. Card selection strategy: 1. Trigger fence to recommend card selection, 2. NFC real-time card selection.

Figure 4 is a fingerprint collection process provided by an embodiment of the present application. As shown in Figure 4, when a card swiping event occurs, determine whether it needs to be collected (1. Valid card, 2. Access card), update the status according to the database, and collect fingerprints (1. Collect GPS, WIFI, CELL, 2. Actively trigger positioning + Scan) and perform data verification based on the fingerprint database.

Figure 5 is a fence construction process provided by an embodiment of the present application. As shown in Figure 5, when the fingerprint collection is successful or the location changes, the fence construction is triggered based on the fingerprint database, and the status update + notification is performed based on the database.

Figure 6 is an AID card selection switching process provided by an embodiment of the present application. As shown in Figure 6, when a fence event or WIFI connection/interruption occurs, relevant processing is triggered, status is updated according to the database, AID is matched according to the fingerprint database, and AID selection card is switched (1. Switch to the corresponding AID, 2. Switch to the preset Set AID); when either WIFIscan update or CELL update occurs, relevant processing is triggered and the status is updated to the database.

Figure 7 is a flow chart of a real-time card cutting method provided by an embodiment of the present application. As shown in Figure 7, the real-time card cutting process includes: NFC controller + firmware NFCC + FW: After entering the site, the firmware FW will report the air interface data when the card is swiped as Lxdebug information. This part is supported by NXP FW; NFC NCI/JNI: The NCI/JNI layer transparently transmits and reports Ledebug data, which requires NXP MW support. The NFC process includes: (1) NfcService receives the underlying card swipe event and reports it to AID; (2) Converts the hexadecimal Lxdebug data into identifiable information and saves it to implement the capture solution; (3) Save the access card name in Config .xml, the corresponding profiles and events are saved in accesscard0.xml,...,accesscard4.xml, and form a mapping between the access card and accesscard0.xml,...,accesscard4.xml; (4) When the user swipes the card again, the real-time captured The profile is compared with the accesscard profile. If there is a match, the wallet is notified to switch to the corresponding access card. Among them, Lxdebug: x here can be 1/2/3/4 corresponding to the data of L1/L2/L3/L4 layer, which is to print out the interaction data between the card reader and the card. This is the information belonging to the debugging log. . NXP is the name of the NFC chip manufacturer. The NCI layer implements the NFC protocol stack, through which the upper layer communicates with NFCC. The implementation of NCI is similar to the implementation of Bluetooth protocol stack in Android. The NCI/JNI layer transparently transmits and reports Ledebug data. Lxdebug reporting is to report these data to the application layer (NfcService) in the form of events through Nci--Jni, and the upper layer gets it. These data can be used to do corresponding things, such as determining which process of card swiping is problematic, such as what the reader's interaction process is, etc.

The feature database stores 5 sets of information, and the comparison algorithm needs to be updated according to optimization. The CPU card swiping traffic POS scenario matches the notification wallet card cutting scenario and is used in the access control scenario.

In some embodiments, after obtaining the first information of the electronic device, the method may further include: when the preset correspondence does not include a correspondence corresponding to the first information. Next, determine the first NFC card based on historical card swiping information and the current time.

The intelligent card selection solution adopted in the embodiment of this application is described below through specific scenarios.

Cards used by users usually include non-CPU access control cards, CPU access control cards, transportation cards, bank cards, electronic identity cards eID, and digital car keys. 1) Cards that require identity verification are not within the scope of smart card cutting (because activation of the card requires verification of user identity, password or biometric identification, automatic activation is not possible), including bank cards, eID, and access cards that require identity verification; 2) Because the transaction logic of CPU access control cards is similar to that of transportation cards and digital car keys, they are classified into one category. Hereinafter, they are collectively referred to as CPU cards. The following access control cards refer to non-CPU access control cards; 3) Encrypted access control cards and non-encrypted access control cards are only in the database. There are differences in reading and verification, and there is no difference in interaction logic, so no distinction is made. 4) Based on the above information, the categories included in the smart card cutting category include: non-CPU access control cards, CPU access control cards, transportation cards, and digital car keys.

Scenarios for using cards include a variety of scenarios. Single card scenario: does not involve smart card cutting; single access card and single CPU card scenario: 1) When using the access card to swipe the card, identify the configuration information Profile of the card reader, and identify the matching algorithm based on the card reader characteristics Select the card and write it into the card reader feature library according to the feature management policy; 2) When the access card is used to swipe the card, fingerprints are collected at the card swiping point and written into the fingerprint library. Subsequently, geofence pre-selected cards are enabled according to the fence policy. The user's card swiping process Enable the real-time card selection function in the access control card; 3) If the access control card has multiple card swiping location points, then set multiple fences according to the different card swiping point locations, and these fences are mapped to the same access control card; 4) If the access control card can be swiped at multiple different locations Readers with behavioral characteristics, then save the behavioral characteristics Profile of each card reader, and these Profiles are mapped to the same card; 5) When the user manually switches the access card to a transportation card and swipes the card, record the bus/subway The card reader's feature profile is written into the card reader feature database according to the card reader feature management policy. Multiple access cards and a single CPU card scenario: Multiple access cards and a single CPU card are both included in the smart card selection category. When a certain access control card is swiped for the first time, it is written into the fingerprint database; when a certain access control card is used to swipe the card, the access control configuration information Profile is identified and saved, and written into the card reader signature database. If a certain access control card has multiple card swiping locations or can be used to swipe multiple access control cards with different characteristics, refer to the above method for a single access control card. When the user manually switches the access control card to the transportation card and swipes the card, the feature profile of the card reader is recorded and written into the card reader feature library according to the card reader feature management policy. Single access card and multiple CPU cards scenarios: For access cards, refer to the above method. Card selection for multiple CPU cards uses the application identifier AID card selection scheme. Scenario with multiple access control cards and multiple CPU cards: Perform card selection based on the above solutions. Multiple access cards scenario: Multiple access cards are included in the smart card selection category. When a certain access control card is swiped for the first time, it is written into the fingerprint database; when a certain access control card is used to swipe the card, the access control profile is identified and saved, and written into the card reader signature database. If a certain access control card has multiple card swiping locations or can be used to swipe multiple access control cards with different characteristics, refer to the above method for a single access control card. Multiple CPU cards scenario: Multiple CPU cards are included in the smart card selection category. Card reader characteristic values are not collected. Cards are selected based on AID, and geofences are not established. The default card is the most recently used card by the user. Among them, the configuration information Profile is the different card-finding command sequences and their time intervals sent by the access control/gate radio frequency. Because different card readers (access control gates, etc.) will send different command sequences, or the time intervals of the commands are different, so Can be used to distinguish card readers.

To sum up, the access control card identification solutions include: using card reader features to identify STR, which has the advantage of being usable indoors and fast recognition speed (0.5s); using WIFI fingerprint library, which has the advantage of being able to be used indoors and pre-cutting the card in advance. Improve card swiping speed; GPS geofencing has the advantage of high positioning accuracy. The identification solutions for CPU cards include: AID identification, which has the advantage of reliability; using card reader characteristics to identify STR, which has the advantage of being suitable for indoor use and fast identification speed. Among them, STR is Standard Terminal Regular, which is the card reader Reader feature recognition function, that is, the device information can be confirmed through the time and regularity of some TypeA, B, and F communication through video RF.

Figures 10-14 are schematic diagrams of five card selection scenarios provided by the embodiment of the present application. As shown in Figure 10, there is only one access control card, and the bus/subway is outside the access control fence. When the user enters the fence, based on the fence policy, the card is switched to the access control card. When the user walks out of the fence, the card is switched to the transportation card.

The bus/subway is outside the access control fence. When the user enters a certain fence , Based on the fence strategy, the card is switched to the access control card of the corresponding fence. When the user walks out of the fence, the card is switched to the traffic card.

As shown in Figure 12, there is an access card and a bus/subway station inside the access card fence. The following method is adopted: the access control fence remains unchanged, and the access control card is selected by default in the fence. When the card is swiped, the card reader AID and the card reader characteristic value are used for matching. If the match is successful, the corresponding card is switched. The bus/subway characteristic values are collected when the card is swiped for the first time, and the judgment condition is that the user chooses to swipe the transportation card in the access fence.

As shown in Figure 13, there are multiple access control card fences, and the large access control card fences intersect. There are no bus/subway card swiping points in the large fence, and there are no intersections in the small access control card fences. Then the preselected card is made based on the WIFI fingerprints of the two access control card swiping points. Use the card reader feature to do real-time card selection. The difference between a large fence and a small fence is that the large fence has a larger range and circle radius, while the small fence has a smaller range and circle radius.

As shown in Figure 14, there are multiple access control cards, and the large access control fence overlaps. The large access control fence contains bus/subway card swiping points. The following methods can be used: collect the card reader characteristics and WIFI fingerprints of access control 1, access control 2, and buses/subways in the fenced area, pre-select cards through WIFI fingerprints, and select cards in real time through card reader characteristics. In the extreme scenario, the card readers of Access Control 1 and Access Control 2 have the same characteristics, and their locations are very close to each other (for example, about 20m). The small access control fences intersect, and smart card selection can be carried out through digital recommendation card selection.
