[0030] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as being limited to the examples set forth herein; on the contrary, these embodiments are provided so that the present disclosure will be more comprehensive and complete, and the concepts of the example embodiments are fully conveyed to those skilled in the art. The described features, structures, or characteristics may be combined in one or more embodiments in any suitable manner. In the following description, many specific details are provided to provide a full understanding of the embodiments of the present disclosure. However, those skilled in the art will appreciate that the technical solutions of the present disclosure may be practiced while omitting one or more of the specific details, or other methods, components, devices, steps, etc. may be adopted. In other cases, known technical solutions are not shown or described in detail to avoid obscuring various aspects of the present disclosure.

[0031] In addition, the accompanying drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the figures represent the same or similar parts, and their repeated description will be omitted. Some of the block diagrams shown in the accompanying drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities can be implemented in software form, or implemented in one or more hardware modules or integrated circuits, or implemented in different networks and / or processor devices and / or microcontroller devices.

[0032] See also Figure 1 , Figure 1 FIG. 1 shows a schematic diagram of the structure of an electronic device suitable for implementing the embodiment of the present disclosure. It should be noted that: Figure 1 The electronic device 100 shown is only an example and should not bring any limitation to the functions and scope of use of the embodiments of the present disclosure.

[0033] like Figure 1 As shown, the electronic device 100 may specifically include: a processor 110, a wireless communication module 120, a mobile communication module 130, a charging management module 140, a power management module 141, a battery 142, a USB (Universal Serial Bus) interface 150, an antenna 1, an antenna 2, an internal memory 161, an external memory interface 162, a display screen 170 and a sensor module 180, etc.

[0034] It is to be understood that the structure illustrated in the embodiment of the present application does not constitute a specific limitation on the electronic device 100. In other embodiments of the present application, the electronic device 100 may include more or fewer components than shown in the figure, or combine some components, or split some components, or arrange the components differently. The components shown in the figure may be implemented in hardware, software, or a combination of software and hardware.

[0035] The processor 110 may include one or more processing units. For example, the processor 110 may include an application processor, a modem processor, a graphics processor, an image signal processor, a controller, a video codec, a digital signal processor, a baseband processor, and / or a neural network processor. Different processing units may be independent devices or integrated into one or more processors. The controller may generate an operation control signal according to the instruction opcode and the timing signal to complete the control of fetching and executing instructions.

[0036] A memory may also be provided in the processor 110 for storing instructions and data. The memory may store instructions for implementing six modular functions: detection instructions, connection instructions, information management instructions, analysis instructions, data transmission instructions, and notification instructions, and the execution is controlled by the processor 110. In some embodiments, the memory in the processor 110 is a cache memory. The memory may store instructions or data that have just been used or are cyclically used by the processor 110. If the processor 110 needs to use the instruction or data again, it may be directly called from the memory, thereby avoiding repeated access, reducing the waiting time of the processor 110, and thus improving the efficiency of the system.

[0037] The wireless communication module 120 can provide wireless communication solutions including wireless LAN, Bluetooth, global navigation satellite system, frequency modulation, NFC technology, UWB (Ultra Wide Band) technology, infrared technology, etc. applied to the electronic device 100. The wireless communication module 120 can be one or more devices integrating at least one communication processing module. The wireless communication module 120 receives electromagnetic waves via the antenna 2, modulates the frequency of the electromagnetic wave signal and performs filtering, and sends the processed signal to the processor 110. The wireless communication module 120 can also receive the signal to be sent from the processor 110, modulate the frequency of the signal, amplify it, and convert it into electromagnetic waves for radiation through the antenna 2.

[0038] In some embodiments, antenna 1 of electronic device 100 is coupled to mobile communication module 130, and antenna 2 is coupled to wireless communication module 120, so that electronic device 100 can communicate with the network and other devices through wireless communication technology.

[0039] Among them, NFC technology is a short-range (within 10 cm) wireless communication technology. Its operating frequency is 13.56MHz. At present, this technology is widely used in people's lives, such as common subways, buses, UnionPay QuickPass and access control systems.

[0040] UWB technology is a type of wireless communication technology that uses narrow pulses (nanosecond or even picosecond pulses) to transmit information, and has the advantages of high bandwidth and low power consumption. The basic characteristics of UWB include the use of non-sinusoidal narrow pulses to transmit data, narrow pulses, and wide bandwidth (500MHz~1.3GHz). Because of these basic characteristics, UWB transmission is less affected by multipath, has low transmission power consumption, and a high transmission rate.

[0041] The charging management module 140 is used to receive charging input from a charger. The charger may be a wireless charger or a wired charger. In some wired charging embodiments, the charging management module 140 may receive charging input from a wired charger through the USB interface 150. In some wireless charging embodiments, the charging management module 140 may receive wireless charging input through a wireless charging coil of the electronic device 100. While the charging management module 140 is charging the battery 142, it may also power the electronic device through the power management module 141.

[0042] The power management module 141 is used to connect the battery 142, the charging management module 140 and the processor 110. The power management module 141 receives input from the battery 142 and / or the charging management module 140, and supplies power to the processor 110, the internal memory 161, the display screen 170 and the wireless communication module 120. The power management module 141 can also be used to monitor parameters such as battery capacity, battery cycle number, battery health status (leakage, impedance), etc. In some other embodiments, the power management module 141 can also be set in the processor 110. In other embodiments, the power management module 141 and the charging management module 140 can also be set in the same device.

[0043] The wireless communication function of the electronic device 100 can be implemented through the antenna 1, the antenna 2, the wireless communication module 120, the mobile communication module 130, the modem processor, the baseband processor, and the like.

[0044] The technical solution of the embodiment of the present disclosure is described in detail below.

[0045] For terminal devices with NFC function, the terminal devices can simulate bus cards, bank cards, access control cards, etc. Therefore, users can directly swipe cards through the terminal devices. When swiping cards through terminal devices, there are often scenarios where it is necessary to switch simulated cards. For example, after the user swipes the bus through the terminal device, he may need to swipe the access control. At this time, the simulated card can be switched.

[0046] At present, since the efficiency of switching analog cards is low, it is possible to switch automatically based on preset time. Specifically, the analog card can be automatically switched according to the user's preset itinerary. For example, the attendance card is preset at 9:00 am, and different cards are automatically switched according to these preset itineraries. However, this method requires the user to set the itinerary in advance. If the itinerary is not set or the itinerary is temporarily changed, the incorrect action of switching the analog card will be made.

[0047] In addition, automatic switching can also be performed based on the characteristic code of the card reader transaction. The card reader refers to the party that actively transmits radio frequency signals and instructions during the NFC transaction process, such as UnionPay POS machines, subway gates, access control card readers, etc. The characteristic code based on the card reader transaction refers to extracting the characteristic fields in the instructions issued by the card reader during the transaction process, judging the card reader type based on these characteristic fields, and realizing automatic card switching. However, this method must obtain the instructions of the card reader before switching cards. From receiving the card reader instruction to parsing the instruction, to card switching, and finally completing the entire transaction, the execution of the entire process requires a certain amount of time (for example, 1 to 2 seconds), which will give users a sluggish card swiping experience, and may even cause card swiping failure due to waiting time.

[0048] In order to solve the above problems, the present disclosure provides a simulation card switching method, a terminal device, a card reader and a computer-readable storage medium to improve the efficiency and correctness of simulation card switching.

[0049] See also Figure 2 , Figure 2 A flowchart of the analog card switching method according to an embodiment of the present disclosure is shown, which is applied to a terminal device and may include the following steps:

[0050] Step S210: after receiving the signal broadcasted by the card reader, establish a communication connection with the card reader.

[0051] Step S220, receiving the parameter information of the card reader itself sent by the card reader; wherein the parameter information is used to indicate the target type of the simulated card supported by the card reader.

[0052] Step S230, when the type of the enabled analog card in the terminal device is different from the target type, the enabled analog card in the terminal device is switched to a analog card of the target type.

[0053] In the analog card switching method of the disclosed embodiment, before the user swipes the card through the terminal device, the terminal device can establish a communication connection with the card reader after receiving the signal sent by the card reader. The card reader sends parameter information to the terminal device, so that the terminal device switches the analog card according to the target type of the analog card supported by the card reader indicated in the parameter information. In this way, the analog card is switched in advance before the user uses it. On the one hand, by intelligently switching the analog card, the user can avoid frequent manual operations and improve the efficiency of switching. On the other hand, directly switching according to the target type of the analog card indicated by the card reader can improve the accuracy of the switching and enhance the user experience.

[0054] See also Figure 3 , Figure 3Another flowchart of the analog card switching method according to the embodiment of the present disclosure is shown, which is applied to a card reader and may include the following steps:

[0055] Step S310: broadcast a signal to establish a communication connection with a terminal device that receives the signal.

[0056] Step S320, after establishing a communication connection with the terminal device, sends its own parameter information to the terminal device, the parameter information is used to indicate the target type of the simulated card supported by the card reader, so that the terminal device switches the enabled simulated card to the simulated card of the target type when the type of the enabled simulated card is different from the target type.

[0057] In the analog card switching method of the disclosed embodiment, before the user swipes the card through the terminal device, the card reader sends a signal through broadcasting, thereby establishing a communication connection with the terminal device that receives the signal. Afterwards, the card reader sends parameter information to the terminal device, so that the terminal device switches the analog card according to the target type of the analog card supported by the card reader indicated in the parameter information. In this way, the analog card is switched in advance before the user uses it. On the one hand, by intelligently switching the analog card, the user can avoid frequent manual operations and improve the efficiency of switching. On the other hand, directly switching according to the target type of the analog card indicated by the card reader can improve the accuracy of the switching and enhance the user experience.

[0058] See also Figure 4 , Figure 4 An interactive flow chart of the analog card switching method according to an embodiment of the present disclosure is shown, which may include the following steps:

[0059] Step S410: the card reader broadcasts a signal.

[0060] Specifically, since the card reader refers to the party that actively transmits radio frequency signals and instructions during the NFC transaction, such as UnionPay POS machines, subway gates, access control card readers, etc. Usually, the card reader can read the cards of many users. For example, the subway gate can read the bus card of every user riding the subway; the access control card reader can read the access control card of every user entering the building, etc. Therefore, when the user swipes the card with a smartphone, the card reader can broadcast and send signals in order to communicate with multiple smartphones.

[0061] In one implementation of the present disclosure, the card reader can broadcast and send an ultra-wideband signal, that is, the card reader can have an ultra-wideband function. In this case, the smart phone can also have an ultra-wideband function. Figure 5 , Figure 5A schematic diagram showing a plurality of different types of card readers broadcasting signals. It can be seen that a plurality of different types of card readers can broadcast ultra-wideband signals. Of course, the communication between the card reader and the terminal device is not limited to ultra-wideband communication. For example, the card reader can also broadcast GPS (Global Positioning System) signals, etc., which are not limited here.

[0062] Step S420: After receiving the above signal, the terminal device establishes a communication connection with the card reader.

[0063] In the disclosed embodiment, the location of the terminal device can be determined by positioning technology. If the location of the terminal device is within a preset area (e.g., near a subway station), the preset area can be a relatively large area, and the terminal device can also detect whether it can receive a signal sent by a card reader. When the distance between the terminal device and the card reader gradually approaches (e.g., 12 meters, etc.), the signal sent by the card reader can be received. At this time, a response signal can be returned to the card reader, and a communication connection can be established with the card reader.

[0064] It should be noted that the communication connection here may be a long-distance communication connection rather than a near-field communication connection. After receiving the ultra-wideband signal broadcasted by the card reader, the terminal device may establish an ultra-wideband communication connection with the card reader.

[0065] In step S430, the card reader continuously monitors the distance between itself and the terminal device, and when it detects that the distance is reduced to a distance threshold, it sends its own parameter information to the terminal device.

[0066] It should be noted that, since ultra-wideband has many functional features, the present disclosure can perform analog card switching based on the ultra-wideband high-precision positioning characteristics (positioning accuracy at the centimeter level). Based on ultra-wideband positioning technology, not only can the exact location of the terminal device be accurately located, but also the user's moving direction relative to a certain card reader can be accurately determined, for example, it can be getting closer or farther away.

[0067] Specifically, the card reader can continuously monitor the distance between itself and the terminal device, and determine whether the terminal is getting closer to the card reader or farther away from the card reader based on the change in the distance. The continuous monitoring can be continuous monitoring or periodic monitoring. For example, in the case of periodic monitoring, the monitoring can be performed every 0.5 seconds or 1 second.

[0068] When the distance between the terminal device and the card reader is monitored to decrease to the distance threshold, the card reader can send its own parameter information to the terminal device. Of course, the distance thresholds corresponding to different card readers may be different. For example, for a subway gate, the distance threshold may be 5 meters, and for an access control card reader, the distance threshold may be 10 meters, etc., which are not limited here. In addition, when the distance is monitored to increase, it indicates that the terminal device is gradually moving away from the card reader, and no processing is required.

[0069] In the disclosed embodiment, the card reader may send its own parameter information in the form of an ultra-wideband instruction. For example, the ultra-wideband instruction may carry parameter information. The parameter information may include the target type of the simulated card supported by the card reader. The types of simulated cards may include: access control cards, bank cards, bus cards, etc. Different card readers support different types of simulated cards. For example, the target type of the simulated card in the parameter information sent by the subway gate is a bus card, the target type of the simulated card in the parameter information sent by the access control card reader is an access control card, and the target type of the simulated card in the parameter information sent by the UnionPay POS machine is a bank card.

[0070] Step S440: after receiving the card reader parameter information sent by the card reader, the terminal device detects whether there is an enabled simulated card in the terminal device.

[0071] In the embodiment of the present disclosure, the NFC function in the terminal device may not be enabled. Therefore, after receiving the parameter information sent by the card reader, it is possible to first detect whether there is an enabled simulated card in the terminal device.

[0072] Step S450, when there is an enabled analog card in the terminal device, and when the type of the enabled analog card in the terminal device is different from the target type, the enabled analog card in the terminal device is switched to a simulated card of the target type.

[0073] Specifically, when the terminal device performs a card swiping operation, one of the simulated cards can be simulated. That is, one of the multiple simulated cards in the terminal device can be enabled. For example, when swiping the access control card, the access control card is enabled, and other cards are not enabled. When swiping the UnionPay POS machine, one of the bank cards is enabled, and other bank cards and access control cards are not enabled. It can be seen that different simulated cards can be enabled for different card readers.

[0074] Therefore, after receiving the parameter information sent by different card readers, the terminal device can directly switch the simulated card according to the target type. In the embodiment of the present disclosure, the switching of the enabled simulated card means setting another simulated card to the enabled state when the currently enabled simulated card is set to the disabled state. For example, after receiving the parameter information sent by the subway gate, the terminal device can be simulated as a bus card. If the currently enabled simulated card is a bus card, no processing is required. If the currently enabled simulated card is a bank card, then the bank card can be set to the disabled state and the bus card can be set to the enabled state.

[0075] It should be noted that multiple cards of the same type may be activated in the terminal device, for example, the user has activated multiple bank cards. At this time, that is, when the number of simulated cards of the target type is multiple, the activated simulated card in the terminal device can be switched to the simulated card of the target type that the user used most recently. For example, when a user consumes at a convenience store, the target type is a bank card, and the user's terminal device has activated the first bank card, the second bank card, and the third bank card. If the user used the second bank card most recently, then the activated simulated card in the terminal device can be switched to the second bank card. In this way, it can be more in line with the user's usage habits, thereby improving the user experience.

[0076] Step S460: When there is no enabled analog card in the terminal device, a prompt message indicating enabling the analog card is displayed.

[0077] In the embodiment of the present disclosure, when the NFC function is not enabled, a prompt message may be displayed to prompt the user to enable the NFC function.

[0078] It should be noted that different card readers may require different NFC radio frequency parameters when performing NFC radio frequency communication. For example, although both Metro Line 1 and Line 2 can swipe bus cards, different subway lines may have subway gates manufactured by different equipment manufacturers, and these gates may require different NFC radio frequency parameters to adapt.

[0079] In one implementation of the present disclosure, the parameter information sent by the card reader may also include the address identification information of the card reader, which may be an IP (Internet Protocol) address, a physical address, etc. Thus, before the user swipes the card through the terminal device, in addition to performing the analog card switching, the radio frequency parameters matching the card reader may be determined according to the address identification information of the card reader. The analog card switching process and the radio frequency parameter setting process may be performed simultaneously or successively, which is not limited here.

[0080] Specifically, appropriate RF parameters can be saved when the terminal device is tested before leaving the factory, and the RF parameters and address identification information are formed into a mapping table, and the mapping table is stored in the memory of the terminal device. In the case where the RF parameters corresponding to the address identification information of the card reader are stored, the RF parameters of the terminal device can be set to the RF parameters corresponding to the address identification information of the card reader, and when the user swipes the card through the terminal device, near-field communication is performed with the card reader according to the RF parameters. In the case where the RF parameters corresponding to the address identification information of the card reader are not stored, the RF parameters of the terminal device can be set to the initial RF parameters, and when the user swipes the card through the terminal device, near-field communication is performed with the card reader according to the initial RF parameters. Among them, the initial RF parameters can be pre-set universal RF parameters, and near-field communication with most card readers is relatively smooth when using the RF parameters.

[0081] See also Figure 6 , Figure 6 Another interactive flow chart of the analog card switching method according to the embodiment of the present disclosure is shown, which may include the following steps:

[0082] Step S610: the card reader broadcasts a signal.

[0083] Step S620: After receiving the above signal, the terminal device establishes a communication connection with the card reader.

[0084] Step S630: the terminal device continuously monitors the distance between itself and the card reader, and when the distance decreases to a distance threshold, sends a request message to the card reader, wherein the parameter information is used to indicate the target type of the simulated card supported by the card reader.

[0085] Step S640: After receiving the request information, the card reader sends its own parameter information to the terminal device.

[0086] Step S650: After receiving the parameter information, the terminal device detects whether there is an enabled simulation card in the terminal device.

[0087] Step S660, when there is an enabled analog card in the terminal device, and when the type of the enabled analog card in the terminal device is different from the target type, the enabled analog card in the terminal device is switched to a simulated card of the target type.

[0088] Step S670: When there is no enabled analog card in the terminal device, a prompt message indicating enabling the analog card is displayed.

[0089] It should be noted that Figure 6 Steps S610, S620 and S650-S670 in the embodiment are respectively Figure 4The processing procedures of steps S410, S420 and S440 to S460 in the embodiment are the same, for details, see Figure 4 The description in the embodiments is sufficient and will not be repeated here.

[0090] In step S630, Figure 4 The difference between the embodiments is that, in addition to the card reader actively and continuously monitoring the distance between itself and the terminal device, the terminal device can also actively and continuously monitor the distance between itself and the card reader. When the distance between the two is monitored to be reduced to a distance threshold, the terminal device can send a request message to the card reader, and the request message is used to make the card reader send parameter information.

[0091] In step S640, after receiving the request information, the card reader may send parameter information to the terminal device.

[0092] In the disclosed embodiment, the above Figure 2 , Figure 3 , Figure 4 and Figure 6 The embodiments all belong to the process of automatically switching the simulation card. The present disclosure also supports the process of manual switching. Specifically, after the user performs a switching operation on the touch screen of the terminal device, the terminal device responds to the user's simulation card switching operation and switches the enabled simulation card in the terminal device to the target simulation card to be switched by the user.

[0093] It should be noted that the user can switch the simulated card at any time. For example, the user can switch manually before the terminal device automatically switches. Then, in this case, since the user has manually switched to the correct simulated card, the terminal device may no longer switch automatically before the user swipes the card.

[0094] In addition, the user can also manually switch after the terminal device automatically switches. For example, if there are multiple analog cards of the same type in the terminal device, the user can manually switch to the analog card they want to use after the terminal device automatically switches. The terminal device can also store the scene and the operation, so that the terminal device can automatically switch to the analog card manually selected by the user when the same scene occurs next time.

[0095] In the analog card switching method of the disclosed embodiment, since the communication distance of NFC technology is generally within 10 cm, compared with the interaction between the terminal device and the card reader only through NFC technology in the related art, before the user brings the terminal device close to the card reader and performs an NFC transaction, the terminal device and the card reader can interact through UWB technology. In this way, the user can complete the switching of the analog card and the switching of the radio frequency parameters in advance at a longer distance (for example, within 1 meter to 5 meters), avoiding the problem of increased card swiping time or even card swiping failure caused by switching when approaching the card reader at a close distance, thereby improving the efficiency and accuracy of analog card switching and improving user experience.

[0096] It should be noted that although the steps of the method in the present disclosure are described in a specific order in the drawings, this does not require or imply that the steps must be performed in this specific order, or that all the steps shown must be performed to achieve the desired results.
