A memory may also be provided in 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 are controlled to be executed by the processor 110. In some embodiments, the memory in the processor 110 is a cache memory. The memory may hold instructions or data that have just been used or recycled by the processor 110. If the processor 110 needs to reuse the instruction or data, it can be called directly from the memory, avoiding repeated accesses, reducing the latency of the processor 110, and thus increasing the efficiency of the system.

The UWB technology is a wireless communication technology, and 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 narrow pulse transmission of data using non-sinusoidal waves, narrow pulse, and wide bandwidth (500MHz to 1.3GHz), and because of these basic characteristics, UWB transmission is less affected by multipath, and has low transmission power consumption and high transmission rate.

The wireless communication function of the electronic device 100 may be implemented by the antenna 1, the antenna 2, the wireless communication module 120, the mobile communication module 130, a modem processor, a baseband processor, and the like.
The technical solutions of the embodiments of the present disclosure are explained in detail below.
For terminal equipment with an NFC function, the terminal equipment can simulate a bus card, a bank card, an access control card and the like. Therefore, the user can directly carry out card swiping operation through the terminal equipment. When the card swiping operation is performed through the terminal device, a scene that the analog card needs to be switched often exists, for example, after a user swipes a bus through the terminal device, an entrance guard may need to be swiped, and at this time, the switching operation of the analog card can be performed.
At present, the method is low in efficiency when the analog card is switched, so that automatic switching can be performed based on preset time. Specifically, the analog cards can be automatically switched according to the preset routes of the user, for example, the attendance cards of 9:00 am are preset, and different cards are automatically switched according to the preset routes. However, this method requires the user to set a trip in advance, and when no trip is set or the trip is temporarily changed, an erroneous operation of switching the analog card is performed.
In addition, automatic switching can be performed based on the characteristic code of the card reader transaction. The card reader is a party which actively transmits radio frequency signals and instructions in the NFC transaction process, such as a UnionPay POS machine, a subway gate machine, an entrance guard card reader and the like. The characteristic code based on the card reader transaction refers to extracting characteristic fields in an instruction issued by the card reader in the transaction process, and judging the type of the card reader according to the characteristic fields to realize automatic card switching. However, the method must acquire the command of the card reader before the card switching action is performed, and the whole transaction is completed after the command of the card reader is received, the command is analyzed, the card switching is performed, and finally, the whole process needs a certain time (for example, 1 to 2 seconds), which may cause a slow card swiping experience for the user, and may even cause a card swiping failure due to too long waiting time.
In order to solve the above problems, the present disclosure provides an analog card switching method, a terminal device, a card reader, and a computer-readable storage medium, so as to improve the efficiency and correctness of analog card switching.
Referring to fig. 2, fig. 2 shows a flowchart of an analog card switching method according to an embodiment of the present disclosure, which is applied to a terminal device, and may include the following steps:
and step S210, after receiving the signal broadcast by the card reader, establishing communication connection with the card reader.
Step S220, receiving self parameter information sent by the card reader; wherein the parameter information is used for indicating the target type of the simulation card supported by the card reader.
Step S230, when the type of the enabled emulation card in the terminal device is different from the target type, switching the enabled emulation card in the terminal device to an emulation card of the target type.
In the analog card switching method of the embodiment of the disclosure, before a user swipes a card through a terminal device, the terminal device can establish communication connection with a card reader after receiving a signal sent by the card reader. The card reader sends the parameter information to the terminal equipment, so that the terminal equipment performs simulated card switching according to the target type of the simulated card supported by the card reader indicated in the parameter information. Thus, the analog card is switched in advance before the user uses it. On the one hand, frequent manual operation of a user can be omitted by intelligently switching the analog cards, and switching efficiency is improved. On the other hand, switching is directly performed according to the target type of the analog card indicated by the card reader, so that the switching accuracy can be improved, and the user experience is improved.
Referring to fig. 3, fig. 3 shows another flowchart of an analog card switching method according to an embodiment of the present disclosure, which is applied to a card reader and may include the following steps:
in step S310, a transmission signal is broadcast to establish a communication connection with the terminal device that received the signal.
Step S320, after establishing a communication connection with the terminal device, sending parameter information of the terminal device to the terminal device, where the parameter information is used to indicate a target type of the analog card supported by the card reader, so that the terminal device switches the enabled analog card to an analog card of the target type when the type of the enabled analog card is different from the target type.
In the analog card switching method according to the embodiment of the present disclosure, before a user swipes a card through a terminal device, a card reader sends a signal through broadcasting, so that a communication connection is established with the terminal device that receives the signal. And then, the card reader sends the parameter information to the terminal equipment, so that the terminal equipment performs simulated card switching according to the target type of the simulated card supported by the card reader indicated in the parameter information. Thus, the analog card is switched in advance before the user uses it. On the one hand, frequent manual operation of a user can be omitted by intelligently switching the analog cards, and switching efficiency is improved. On the other hand, switching is directly performed according to the target type of the analog card indicated by the card reader, so that the switching accuracy can be improved, and the user experience is improved.
Referring to fig. 4, fig. 4 shows an interactive flowchart of an analog card switching method according to an embodiment of the present disclosure, which may include the following steps:
step S410, the card reader broadcasts a sending signal.
Specifically, the card reader is a party which actively transmits radio frequency signals and instructions in the NFC transaction process, such as a union pay POS machine, a subway gate, an entrance guard card reader, and the like. In general, a card reader can read cards of many users, for example, a subway gate can read a bus card of each user who takes a subway; the access card reader can read the access card of each user entering the building. Therefore, when a user swipes a card through the smart phone, the card reader can broadcast a transmission signal to communicate with a plurality of smart phones.
In an implementation manner of the present disclosure, the card reader may broadcast and transmit an ultra-wideband signal, that is, the card reader may have an ultra-wideband function, and in this case, the smart phone may also have an ultra-wideband function. Referring to fig. 5, fig. 5 shows a schematic diagram of the broadcast transmission of signals by a plurality of different types of readers. It can be seen that many 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 the ultra-wideband communication, and for example, the card reader may broadcast a GPS (global positioning system) signal or the like, which is not limited herein.
Step S420, after receiving the signal, the terminal device establishes a communication connection with the card reader.
In the embodiment of the disclosure, the location of the terminal device may be determined through a positioning technology, and if the location of the terminal device is within a preset area range (for example, near a subway station), the preset area range may be a larger range, and the terminal device may also detect whether a signal sent by a card reader may be received. As the distance between the terminal device and the reader approaches gradually (e.g., 12 meters, etc.), a signal transmitted by the reader may be received. At this time, a response signal can be returned to the card reader, and communication connection can be established with the card reader.
It should be noted that the communication connection here may be a communication connection at a longer distance, not a near field communication connection. After receiving the ultra-wideband signal broadcast by the card reader, the terminal device can establish ultra-wideband communication connection with the card reader.
And step S430, the card reader continuously monitors the distance between the card reader and the terminal equipment, and sends the parameter information of the card reader to the terminal equipment when the monitored distance is reduced to a distance threshold value.
It should be noted that, because the ultra-wideband has many functional features, the present disclosure can perform the switching of the analog card based on the high-precision positioning characteristic (the positioning precision is in the centimeter level) of the ultra-wideband. Based on the ultra-wideband positioning technology, not only the accurate position of the terminal device can be accurately positioned, but also the moving direction of the user relative to a certain card reader can be accurately determined, for example, the user can get closer to or get farther away from the certain card reader.
Specifically, the card reader may continuously monitor the distance between itself and the terminal device, and determine whether the terminal is closer to the card reader or farther away from the card reader according to the change of the distance. The continuous monitoring may be a constant monitoring or a periodic monitoring. For example, in the periodic monitoring, the monitoring may be performed every 0.5 seconds, 1 second, or the like.
When it is monitored that the distance between the terminal device and the card reader is reduced to a distance threshold value, the card reader can send parameter information of the card reader to the terminal device. Of course, the distance thresholds may be different for different readers. For example, the distance threshold may be 5 meters for a subway gate, 10 meters for an entrance guard reader, and the like, which is not limited herein. In addition, when the distance is monitored to be increased, the fact that the terminal equipment is gradually far away from the card reader is indicated, and the terminal equipment can be not processed.
In the embodiment of the disclosure, the card reader may send its own parameter information in an ultra-wideband command manner, for example, the ultra-wideband command may carry the parameter information. The target types of the simulated cards supported by the card reader can be included in the parameter information. The types of analog cards may include: access cards, bank cards, bus cards, etc., and the types of analog cards supported by different card readers are different. For example, the target type of the analog card in the parameter information sent by the subway gate is a bus card, the target type of the analog card in the parameter information sent by the entrance guard card reader is an entrance guard card, and the target type of the analog card in the parameter information sent by the Unionpay POS machine is a bank card.
Step S440, after receiving the parameter information of the card reader sent by the card reader, the terminal device detects whether there is an enabled analog card in the terminal device.
In the embodiment of the present disclosure, there may be a case that the NFC function in the terminal device is not turned on, and therefore, after receiving the parameter information sent by the card reader, it may be detected whether an enabled analog card exists in the terminal device.
Step S450, when the enabled analog card exists in the terminal device and the type of the enabled analog card in the terminal device is different from the target type, switching the enabled analog card in the terminal device to the analog card of the target type.
Specifically, when the terminal device performs the card swiping operation, one of the simulated cards can be simulated. That is, one of the analog cards may be enabled among the plurality of analog cards in the terminal device. For example, when swiping the gate, the gate card is enabled and the other cards are not. When the bank POS machine is swiped, one bank card is started, and other bank cards, access control cards and the like are not started. It can be seen that different analog cards may be enabled for different card readers.
Therefore, after receiving the parameter information sent by different card readers, the terminal equipment can directly switch the simulation cards according to the target types. In the embodiment of the disclosure, the switching of the enabled analog card means that when the currently enabled analog card is set to the disabled state, another analog card is set to the enabled 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 analog card is a bus card, no processing may be performed. If the currently enabled analog card is a bank card, the bank card can be set to be in an enabled state, and the bus card can be set to be in an disabled state.
It should be noted that a plurality of cards of the same type may be opened in the terminal device, for example, a user opens a plurality of bank cards. At this time, that is, when the number of the target type of the emulation cards is plural, the emulation card that has been enabled in the terminal device may be switched to the emulation card of the target type that the user used last time. For example, when the user consumes in a convenience store, the target type is a bank card, the first bank card, the second bank card and the third bank card are opened in the terminal device of the user, and if the second bank card is used by the user last time, the enabled analog card in the terminal device can be switched to the second bank card. Therefore, the use habit of the user can be better met, and the user experience can be improved.
Step S460, when the enabled analog card does not exist in the terminal device, displaying a prompt message indicating that the analog card is enabled.
In the embodiment of the present disclosure, when the NFC function is not enabled, a prompt message may be displayed for prompting a user to start the NFC function.
It should be noted that, when different card readers perform NFC radio frequency communication, required NFC radio frequency parameters may be different. For example, although both subway line No. 1 and subway line No. 2 can be swiped for bus cards, different subway lines may be subway gates made by different equipment manufacturers, which may require different NFC radio frequency parameters to adapt.
In an implementation manner of the present disclosure, the parameter information sent by the card reader may further include address identification information of the card reader, where the address identification information may be an IP (Internet Protocol) address, a physical address, and the like. Therefore, before the user swipes the card through the terminal equipment, the radio frequency parameters matched with the card reader can be determined according to the address identification information of the card reader besides the simulated card switching. The process of switching the analog card and the process of setting the radio frequency parameter may be performed simultaneously or sequentially, which is not limited herein.
Specifically, the appropriate radio frequency parameters may be saved when performing a background test before the terminal device leaves the factory, the radio frequency parameters and the address identification information may form a mapping table, and the mapping table may be stored in the memory of the terminal device. Under the condition that the radio frequency parameters corresponding to the address identification information of the card reader are stored, the radio frequency parameters of the terminal equipment can be set as the radio frequency parameters corresponding to the address identification information of the card reader, and near field communication is carried out with the card reader according to the radio frequency parameters when a user carries out card swiping operation through the terminal equipment. Under the condition that the radio frequency parameters corresponding to the address identification information of the card reader are not stored, the radio frequency parameters of the terminal equipment can be set as initial radio frequency parameters, and near field communication is carried out with the card reader according to the initial radio frequency parameters when a user carries out card swiping operation through the terminal equipment. The initial radio frequency parameters can be preset general radio frequency parameters, and the radio frequency parameters are smooth when the radio frequency parameters are in near field communication with most card readers.
Referring to fig. 6, fig. 6 shows another interaction flowchart of the analog card switching method according to the embodiment of the disclosure, which may include the following steps:
step S610, the card reader broadcasts a transmission signal.
And step S620, after receiving the signal, the terminal equipment establishes communication connection with the card reader.
Step S630, the terminal device continuously monitors the distance between itself and the card reader, and sends request information to the card reader when the distance decreases to the distance threshold. Wherein the parameter information is used for indicating the target type of the simulation card supported by the card reader.
And step S640, after receiving the request information, the card reader sends the parameter information of the card reader to the terminal equipment.
Step S650, after receiving the parameter information, the terminal device detects whether there is an enabled analog card in the terminal device.
Step S660, when the enabled analog card exists in the terminal device and the type of the enabled analog card in the terminal device is different from the target type, switching the enabled analog card in the terminal device to the analog card of the target type.
Step S670, when the enabled analog card does not exist in the terminal device, displaying a prompt message indicating that the analog card is enabled.
It should be noted that steps S610, S620, and S650 to S670 in the embodiment of fig. 6 are the same as the processing procedures of steps S410, S420, and S440 to S460 in the embodiment of fig. 4, and specific reference may be made to the description in the embodiment of fig. 4, which is not described herein again.
In step S630, unlike the embodiment of fig. 4, in addition to the card reader actively and continuously monitoring the distance between itself and the terminal device, the terminal device may also actively and continuously monitor the distance between itself and the card reader. When the distance between the terminal device and the card reader is monitored to be reduced to the distance threshold value, the terminal device can send request information to the card reader, and the request information is used for enabling the card reader to send parameter information.
In step S640, the card reader may send the parameter information to the terminal device after receiving the request information.
In the embodiment of the present disclosure, the above embodiments in fig. 2, fig. 3, fig. 4, and fig. 6 all belong to a process of automatically switching analog cards. The disclosure also supports a manual switching process, specifically, after a user performs a switching operation on a touch screen of the terminal device, the terminal device responds to the analog card switching operation of the user, and switches an enabled analog card in the terminal device to a target analog card to be switched by the user.
It should be noted that the user can switch the analog card at any time. For example, the user may manually switch before the terminal device automatically switches. In this case, then, the terminal device may no longer automatically switch until the user swipes the card, since the user has manually switched to the correct emulation card.
In addition, the user can perform manual switching after the terminal equipment is automatically switched. For example, there are a plurality of analog cards of the same type in the terminal device, and after the terminal device is automatically switched, the user manually switches to the analog card that the user wants to use. The terminal device may also store the scene and the operation, so that the terminal device may also automatically switch to the simulated card manually selected by the user in the case that the same scene appears next time.
In the analog card switching method according to the embodiment of the disclosure, since the communication distance of the NFC technology is generally within 10 centimeters, compared with the interaction between the terminal device and the card reader only through the NFC technology in the related art, before the user brings the terminal device close to the card reader and executes the NFC transaction, the terminal device and the card reader may interact through the UWB technology. Therefore, 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 1-5 meters), and the problems of increased card swiping time and even card swiping failure caused by switching when the user is close to the card reader at a short distance are avoided, so that the efficiency and the accuracy of the switching of the analog card can be improved, and the user experience is improved.
It should be noted that although the various steps of the methods of the present disclosure are depicted in the drawings in a particular order, this does not require or imply that these steps must be performed in this particular order, or that all of the depicted steps must be performed, to achieve desirable results. Additionally or alternatively, certain steps may be omitted, multiple steps combined into one step execution, and/or one step broken down into multiple step executions, etc.
