[0023] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. It is understood that the specific embodiments described herein are only used to explain the related applications, rather than to limit the applications. It should also be noted that, for ease of description, only the parts related to the related applications are shown in the drawings.

[0024] As mobile phones have more and more functions and the space is becoming more and more compact, all related functions and devices in mobile phones are moving towards miniaturization, and the area of ​​NFC antennas is also moving towards smaller size; as the available area of ​​NFC decreases, the overall performance of NFC antennas also shows a downward trend. The direct impact on the parameters is that the sensing area becomes smaller, especially in reader mode. The card reading area is small and it is difficult for users to find the strong coupling point, which leads to card reading failure; that is, how to improve the performance of NFC card reading to ensure the success rate of NFC card reading is a technical problem that needs to be solved urgently.

[0025] In order to solve the above problems, in an embodiment of the present application, when the electronic device reads the target card based on the near field communication NFC antenna, it obtains the first detuning quantization parameter corresponding to the NFC antenna; wherein the first detuning quantization parameter represents the detuning degree parameter of the NFC antenna when the target card is in different coupling positions; coupling position indication information is generated according to the first detuning quantization parameter to indicate the correct moving direction of the target coupling position; when the target card is in the target coupling position, the target card is read according to the target coupling position. This can effectively improve the performance of NFC card reading and ensure the success rate of NFC card reading.

[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0027] Figure 1 Schematic diagram of the implementation process of the NFC card reading method proposed in this application embodiment Figure 1 ,like Figure 1 As shown, in an embodiment of the present application, the method for an electronic device to perform NFC card reading may include the following steps:

[0028] Step 101: When reading a target card based on an NFC antenna, obtain a first detuning quantization parameter corresponding to the NFC antenna; wherein the first detuning quantization parameter represents a detuning degree parameter of the NFC antenna when the target card is in different coupling positions.

[0029] In an embodiment of the present application, the electronic device can obtain a first detuning quantization parameter corresponding to the NFC antenna when reading a target card based on a near field communication NFC antenna; wherein the first detuning quantization parameter represents a detuning degree parameter of the NFC antenna when the target card is in different coupling positions.

[0030] It should be noted that in the embodiments of the present application, the electronic device can be any device with communication and storage functions, and the electronic device can have resource selection requirements. For example, the electronic device can be a smart lock, a tablet computer, a mobile phone, an e-reader, a remote control, a personal computer (PC), a laptop computer, a vehicle-mounted electronic device, an Internet TV, a wearable electronic device, a personal digital assistant (PDA), a portable media player (PMP), a navigation device, and other electronic devices.

[0031] It should be noted that, in the embodiments of the present application, the electronic device may include an NFC antenna for implementing some NFC functions; the electronic device acts as an external antenna interface (TX) end, and when the target card is close to the NFC antenna, the NFC antenna will produce a detuning phenomenon; the tighter the coupling, the greater the degree of detuning, and it is easier to read the card.

[0032] Further, in an embodiment of the present application, a script may be set to quantify the degree of detuning of the NFC antenna, that is, to obtain a detuning quantization parameter. When the detuning degree of the NFC antenna is greater, the detuning quantization parameter is also greater.

[0033] Furthermore, in an embodiment of the present application, the target card represents a card attached to an electronic device for NFC card reading; the target card may be a smart card, for example, the smart card may include an ordinary smart card, a standard smart card, a small smart card, and a special-shaped smart card, etc.

[0034] Exemplarily, in an embodiment of the present application, the target card is an access card, and the electronic device can read the access card based on the NFC antenna. During the reading, the access card is attached to the electronic device.

[0035] Exemplarily, in an embodiment of the present application, the target card is an ID card, and the electronic device can read the ID card based on the NFC antenna. During the reading, the ID card is attached to the electronic device.

[0036] Furthermore, in an embodiment of the present application, the first detuning quantization parameter refers to a detuning quantization parameter corresponding to the NFC antenna when a target card is attached to the electronic device.

[0037] Furthermore, in an embodiment of the present application, the electronic device can also obtain a second detuning quantization parameter corresponding to the NFC antenna in a no-load state; wherein the no-load state represents a state of no card reading; the second detuning quantization parameter represents a detuning degree parameter of the NFC antenna in the no-load state; that is, the second detuning quantization parameter refers to the detuning quantization parameter of the NFC antenna when there is no target card attached to the electronic device and the electronic device does not perform NFC card reading.

[0038] Further, in an embodiment of the present application, the first detuning quantization parameter includes an initial detuning quantization parameter and a third detuning quantization parameter; wherein the initial detuning quantization parameter represents a detuning degree parameter of the NFC antenna corresponding to an initial coupling position of the target card when the target card is in an initial attachment state; the third detuning quantization parameter represents a detuning degree parameter of the NFC antenna corresponding to a real-time coupling position of the target card when the target card moves in a target moving direction.

[0039] It should be noted that, in the embodiments of the present application, the initial attachment state refers to the state in which the target card is attached to the electronic device and the target card has not moved; thus, the initial coupling position is the coupling position corresponding to when the target card begins to be attached to the electronic device and has not moved.

[0040] Further, in an embodiment of the present application, after the target card moves in the target moving direction, its corresponding coupling position is the real-time coupling position, and the third detuning quantization parameter is the detuning degree parameter of the NFC antenna corresponding to the real-time coupling position.

[0041] It should be noted that in the embodiments of the present application, the target movement direction can be any direction, for example, the target movement direction can be any direction of up, down, left, and right, or any direction of upper left, upper right, lower left, lower right, etc., and the present application does not make any specific limitation.

[0042] That is to say, in the embodiment of the present application, when the target card moves according to the target moving direction, it can move in any direction, and the arbitrarily selected direction is the target moving direction.

[0043] Further, in an embodiment of the present application, the first detuning quantization parameter and the second detuning quantization parameter are any one of detuning data, current data, frequency data, and received signal strength indication (RSSI) data.

[0044] Exemplarily, in an embodiment of the present application, the detuning quantization parameter adopts detuning data. First, the electronic device can perform no-load self-calibration processing to obtain detuning data (second detuning quantization parameter) in the no-load state. For example, the second detuning quantization parameter is M1. Then, when the electronic device detects that a target card is attached, the detuning data at this time is obtained, that is, the initial detuning quantization parameter, expressed as M2; when the target card is detected to move in any target moving direction, the detuning data of the real-time coupling position can be obtained, that is, the third detuning quantization parameter, expressed as M3.

[0045] Further, in an embodiment of the present application, the third detuning quantization parameter may be acquired in a manner of capturing at preset time intervals through a script setting, that is, the current detuning quantization parameter is acquired once at every preset time interval.

[0046] Furthermore, in the embodiments of the present application, the specific value of the preset time interval is not limited in the present application.

[0047] Exemplarily, in an embodiment of the present application, after the electronic device performs no-load self-calibration, when it detects that a target card is attached, it obtains an initial detuning quantization parameter, and starts to obtain a third detuning quantization parameter at a preset time interval. For example, if the preset time interval is 0.5 seconds, the third detuning quantization parameter is obtained every 0.5 seconds.

[0048] Step 102: Generate coupling position indication information according to the first detuning quantization parameter to indicate a correct moving direction of the target coupling position.

[0049] In an embodiment of the present application, when the electronic device reads the target card based on the NFC antenna, after obtaining the first detuning quantization parameter corresponding to the NFC antenna, it can generate coupling position indication information according to the first detuning quantization parameter to indicate the correct moving direction of the target coupling position.

[0050] Further, in an embodiment of the present application, the coupling position indication information may be used to indicate whether the current target moving direction is correct, that is, whether it is a direction close to a strongly coupled target coupling position.

[0051] It can be understood that in the embodiment of the present application, the target coupling position is a strong coupling position, which is a position that is conducive to NFC card reading.

[0052] It should be noted that, in the embodiments of the present application, the correct moving direction is the target moving direction or a direction opposite to the target moving direction.

[0053] That is to say, in an embodiment of the present application, when a user uses an electronic device to perform NFC card reading, the electronic device can generate coupling position indication information based on the first detuning quantization parameter to instruct the user to move the target card in the correct moving direction indicated by the coupling position indication information, thereby guiding the user to quickly find a better coupling position to achieve efficient card reading.

[0054] Furthermore, in some embodiments of the present application, when the electronic device generates coupling position indication information according to the first detuning quantization parameter, it can determine coupling reference data corresponding to the real-time coupling position according to the first detuning quantization parameter and the second detuning quantization parameter; and generate the coupling position indication information according to the coupling reference data.

[0055] It should be noted that, in an embodiment of the present application, the coupling reference data can be used to determine whether the detuning degree of the current NFC antenna is increasing, that is, whether the coupling degree is increasing, so as to determine whether the current target movement direction is conducive to finding a strongly coupled target coupling position, and then generate coupling position indication information.

[0056] Furthermore, in some embodiments of the present application, when the electronic device determines the coupling reference data corresponding to the real-time coupling position based on the first detune quantization parameter and the second detune quantization parameter, it can perform a subtraction operation on the initial detune quantization parameter and the second detune quantization parameter to obtain first coupling data; perform a subtraction operation on the third detune quantization parameter and the second detune quantization parameter to obtain second coupling data; and perform a subtraction operation on the second coupling data and the first coupling data to obtain coupling reference data.

[0057] Exemplarily, in an embodiment of the present application, the electronic device obtains the second detuning quantization parameter in the no-load state as M1. When the electronic device detects that a target card is attached, it determines that the initial detuning quantization parameter at this time is M2, and the first coupling data is A1=M2-M1; after the target card moves in any direction, the electronic device obtains the third detuning quantization parameter as M3, and the second coupling data is A2=M3-M1; and then a subtraction operation can be performed on A2 and A1 to obtain the coupling reference data A2-A1.

[0058] It should be noted that, in an embodiment of the present application, when a target card is attached to the electronic device, the detuning degree corresponding to the NFC antenna should be greater than the detuning degree in the no-load state, that is, the first coupling data obtained by subtracting the second detuning quantization parameter from the initial detuning quantization parameter should be greater than 0; further, when the target card moves in a certain target moving direction, if the direction is conducive to coupling, the detuning degree of the NFC antenna will be greater, that is, at this time, the third detuning quantization parameter should be greater than the initial detuning quantization parameter, so that the second coupling data obtained by subtracting the second detuning quantization parameter from the third detuning quantization parameter is greater than the first coupling data obtained by subtracting the second detuning quantization parameter from the initial detuning quantization parameter, that is, at this time, the coupling reference data should be greater than 0; and if the target moving direction is not conducive to coupling, the detuning degree of the NFC antenna will decrease, then at this time, the third detuning quantization parameter should be less than the initial detuning quantization parameter, so that the second coupling data obtained by subtracting the second detuning quantization parameter from the third detuning quantization parameter is less than the first coupling data obtained by subtracting the second detuning quantization parameter from the initial detuning quantization parameter, that is, at this time, the coupling reference data should be less than 0.

[0059] Further, in some embodiments of the present application, the coupling position indication information may include first indication information and second indication information.

[0060] Furthermore, in some embodiments of the present application, when the electronic device generates coupling position indication information based on coupling reference data, if the coupling reference data is greater than a preset value, it generates first indication information to instruct to continue moving the target card in the target moving direction; if the coupling reference data is less than the preset value, it generates second indication information to instruct to move the target card in a direction opposite to the target moving direction.

[0061] It should be noted that, in the embodiments of the present application, the preset value may be 0 or other values.

[0062] Exemplarily, in an embodiment of the present application, assuming that the preset value is 0, when the electronic device determines that the current coupling reference data is greater than 0, a first indication information is generated, that is, the current target movement direction is correct, and the user can be instructed to continue moving the target card in the current target movement direction to find the target coupling position; and when the electronic device determines that the current coupling reference data is less than 0, a second indication information is generated to instruct the user to move the target card in the direction opposite to the target movement direction.

[0063] Furthermore, in an embodiment of the present application, the electronic device may display the first indication information or the second indication information based on any one of a floating window, a floating ball, and an APP.

[0064] Furthermore, in an embodiment of the present application, when the electronic device displays the first indication information or the second indication information, it can indicate the correct moving direction by displaying specific data such as detuned quantization parameters and coupling reference data, and can also indicate patterns such as arrows.

[0065] For example, in the embodiments of the present application, Figure 2 Implementation diagram of the NFC card reading method proposed in this application embodiment Figure 1 ,like Figure 2 The figure shows a schematic diagram of coupling position indication information displayed by an electronic device based on a floating window. For example, a floating window is displayed through a user interface (User Interface, UI) design, and the coupling position indication information is displayed in the floating window. For example, the coupling position indication information is the first indication information, and the current target movement direction is left, then the first indication information can be a left arrow to indicate that the user can continue to move the target card to the left.

[0066] For example, in the embodiments of the present application, Figure 3 Implementation diagram of the NFC card reading method proposed in this application embodiment Figure 2 ,like Figure 3 The figure shows a floating ball displayed by an electronic device through an electronic screen; a function or APP for displaying coupling position indication information can be opened based on the floating ball, thereby displaying the coupling position indication information.

[0067] For example, in the embodiments of the present application, Figure 4 Implementation diagram of the NFC card reading method proposed in this application embodiment Figure 3 ,like Figure 4 Shown is an icon of an APP displayed on an electronic screen of an electronic device, where the APP can be used to display coupling position indication information.

[0068] Furthermore, in an embodiment of the present application, the electronic device may also generate third indication information to indicate that the current coupling position is better and reading can be performed, that is, the target coupling position has been found.

[0069] It can be understood that in an embodiment of the present application, the user can move the target card based on the coupling position indication information and move the target card according to the prompted correct moving direction, for example, the target moving direction is right; when at moment T1, the electronic device determines that the coupling reference data is greater than the preset value based on the current real-time coupling position, that is, the detuning degree of the NFC antenna increases and the coupling degree increases, then a first indication information can be generated to instruct the user to continue moving the target card to the right, and at moment T2, the electronic device determines that the coupling reference data is less than the preset value based on the current real-time coupling position, then a second indication information can be generated to instruct the user to move the target card to the left until the target coupling position is found, and a third indication information is generated to instruct the user that the current target card is already in the target coupling position and can stop moving.

[0070] Step 103: When the target card is at the target coupling position, the target card is read according to the target coupling position.

[0071] In an embodiment of the present application, after the electronic device generates coupling position indication information according to the first detuning quantization parameter to indicate the correct moving direction of the target coupling position, it can complete reading of the target card according to the target coupling position when the target card is in the target coupling position.

[0072] In summary, in the embodiments of the present application, the variation trend of the detuning quantization parameter is used to determine the tightness of the current coupling, thereby enabling the user to quickly find a better coupling position, achieve efficient card reading, and improve NFC card reading performance.

[0073] The embodiment of the present application provides an NFC card reading method, in which the electronic device obtains a first detuning quantization parameter corresponding to the NFC antenna when reading a target card based on a near field communication NFC antenna; wherein the first detuning quantization parameter represents the detuning degree parameter of the NFC antenna when the target card is in different coupling positions; coupling position indication information is generated according to the first detuning quantization parameter to indicate the correct moving direction of the target coupling position; when the target card is in the target coupling position, the target card is read according to the target coupling position. It can be seen that in the embodiment of the present application, when the electronic device performs NFC card reading on the target card, the detuning degree of the NFC antenna at the current coupling position can be determined by obtaining the first detuning quantization parameter of the NFC antenna corresponding to the coupling position where the target card is attached in real time, thereby generating coupling position indication information to guide the moving direction that can approach the strong coupling point that is easy to read the card, that is, the correct moving direction of the target coupling position, so that when it is determined that the target card moves to the target coupling position, the target card can be read according to the target coupling position, so as to achieve efficient NFC card reading, effectively improve the performance of NFC card reading, and ensure the success rate of NFC card reading.

[0074] Based on the above embodiment, in another embodiment of the present application, exemplarily, the electronic device is a mobile phone, Figure 5 Schematic diagram of the implementation process of the NFC card reading method proposed in this application embodiment Figure 2 ,like Figure 5 As shown, the mobile phone can first perform no-load self-calibration without performing NFC card reading to obtain the second detuning quantization parameter in the no-load state (step 201), and then when it is detected that a target card is attached, that is, when it is necessary to start NFC card reading, first when the target card is in the initial attachment state, the initial detuning quantization parameter is obtained (step 202), and then when it is detected that the target card moves in the target moving direction, the third detuning quantization parameter is obtained (step 203), so as to determine the coupling reference data according to the above detuning quantization parameters, including the second detuning quantization parameter, the initial detuning quantization parameter and the third detuning quantization parameter (step 204), so as to generate the coupling position indication information based on the coupling reference data, and further, when the coupling reference data is greater than the preset value, the first indication information is generated (step 205), and when the coupling reference data is less than the preset value, the second indication information is generated (step 206).

[0075] Further, in the embodiment of the present application, when the mobile phone detects that the target card moves to the target coupling position and completes the reading of the target card according to the target coupling position, the above-mentioned Figure 5 process.

[0076] It should be noted that, in the embodiment of the present application, the mobile phone serves as the TX end. When the target card is close to the NFC antenna, the NFC antenna will produce a detuning phenomenon; when the coupling is tighter, the detuning degree is greater, and it is easier to read the card; when the detuning quantization parameter is used to measure the detuning degree of the NFC antenna, the greater the detuning degree, the greater the detuning quantization parameter, so that the correct moving direction of the target card can be determined by the change of the detuning quantization parameter to achieve more efficient card reading.

[0077] Further, in an embodiment of the present application, a script may be set to quantify the degree of detuning of the NFC antenna, that is, to obtain a detuning quantization parameter. When the detuning degree of the NFC antenna is greater, the detuning quantization parameter is also greater.

[0078] It should be noted that, in the embodiments of the present application, the initial attachment state refers to the state in which the target card is attached to the mobile phone and has not moved; thus, the initial coupling position is the coupling position corresponding to when the target card begins to attach to the mobile phone and has not moved.

[0079] Further, in an embodiment of the present application, after the target card moves in the target moving direction, its corresponding coupling position is the real-time coupling position, and the third detuning quantization parameter is the detuning degree parameter of the NFC antenna corresponding to the real-time coupling position.

[0080] Furthermore, in an embodiment of the present application, the target moving direction may be any direction, for example, the target moving direction may be any direction of up, down, left, and right, or any direction of upper left, upper right, lower left, and lower right.

[0081] Further, in an embodiment of the present application, the first detuning quantization parameter and the second detuning quantization parameter are any one of detuning data, current data, frequency data and RSSI data.

[0082] Exemplarily, in an embodiment of the present application, the detuning quantization parameter adopts detuning data, and the correct moving direction of the target card is quickly determined according to the change trend of the detuning data to achieve efficient card reading.

[0083] Exemplarily, in an embodiment of the present application, the mobile phone first performs no-load self-calibration processing to obtain detuning data in the no-load state, such as M1, and then when the electronic device detects that a target card is attached, the detuning data at this time is obtained, which is represented by M2; when the target card is detected to move in any target moving direction, the detuning data of the real-time coupling position can be captured at a preset time interval, which is represented by M3.

[0084] Among them, in the embodiments of the present application, the original instantaneous grabbing mechanism of the mobile phone in the loaded state can be improved and adjusted to continuously grab at preset time intervals.

[0085] Furthermore, in some embodiments of the present application, when the electronic device determines the coupling reference data corresponding to the real-time coupling position based on the first detune quantization parameter and the second detune quantization parameter, it can perform a subtraction operation on the initial detune quantization parameter and the second detune quantization parameter to obtain first coupling data; perform a subtraction operation on the third detune quantization parameter and the second detune quantization parameter to obtain second coupling data; and perform a subtraction operation on the second coupling data and the first coupling data to obtain coupling reference data.

[0086] Exemplarily, in an embodiment of the present application, the electronic device obtains the second detuning quantization parameter in the no-load state as M1. When the electronic device detects that a target card is attached, it determines that the initial detuning quantization parameter at this time is M2, and the first coupling data is A1=M2-M1; after the target card moves in any direction, the electronic device obtains the third detuning quantization parameter as M3, and the second coupling data is A2=M3-M1; and then a subtraction operation can be performed on A2 and A1 to obtain the coupling reference data A2-A1.

[0087] Further, in an embodiment of the present application, assuming that the preset value is 0, when the coupling reference data A2-A1 is greater than 0, it indicates that the degree of detuning is greater and the coupling is stronger, then a first indication information is generated, that is, the current target movement direction is correct, and the user can be instructed to continue moving the target card in the current target movement direction to find the target coupling position; and when the coupling reference data A2-A1 is less than 0, a second indication information is generated to instruct the user to move the target card in the direction opposite to the target movement direction.

[0088] Exemplarily, in an embodiment of the present application, the electronic device is a mobile phone. The following Table 1 shows the detuning quantization parameter obtained through experiments. The detuning quantization parameter adopts detuning data, including the second detuning quantization parameter corresponding to the NFC antenna in an unloaded state, and the initial detuning quantization parameter and the third detuning quantization parameter corresponding to the NFC antenna when loaded and the target card is in the initial attachment state; it can be seen that for the first column of data, the second detuning quantization parameter corresponding to the NFC antenna in the unloaded state is 160, when the target card is attached, the initial detuning quantization parameter is 13408, and the target moving direction is upward, for example, moving upward by 1.After 3cm, the third detuning quantization parameter obtained is 3680, so the first coupling data can be 13408-160=13248, the second coupling data is 3680-160=3520, and the coupling reference data is 3520-13248=-9728. Assuming that the preset value is 0, the second indication information can be generated, indicating the movement in the opposite direction to the current target movement direction, that is, moving downward; for the second column of data, the second detuning quantization parameter corresponding to the NFC antenna in the unloaded state is 160, and when the target card is attached, the initial detuning quantization parameter is 1596 8, the target moving direction is downward, for example, after moving downward for a certain distance, the third detuning quantization parameter obtained is 7840, so that the first coupling data can be 15968-160=15808, the second coupling data is 7840-160=7680, and the coupling reference data is 7680-15808=-8128. Assuming that the preset value is 0, the second indication information can be generated, indicating moving in the opposite direction to the current target moving direction, that is, moving upward; for the third column data, the second detuning quantization parameter corresponding to the NFC antenna in the unloaded state is 160. When the target is attached When the card is used, the initial detuning quantization parameter is 15616, and the target moving direction is left. For example, after moving a certain distance to the left, the third detuning quantization parameter obtained is 14208, so that the first coupling data can be 15616-160=15456, the second coupling data is 14208-160=14048, and the coupling reference data is 14048-15456=-1408. Assuming that the preset value is 0, the second indication information can be generated, indicating moving in the opposite direction to the current target moving direction, that is, moving to the right; for the fourth column of data, the NFC antenna in the unloaded state The corresponding second detuning quantization parameter is 160. When the target card is attached, the initial detuning quantization parameter is 15776. The target moving direction is right. For example, after moving a certain distance to the right, the third detuning quantization parameter obtained is 10080, so that the first coupling data can be 15776-160=15616, the second coupling data is 10080-160=9920, and the coupling reference data is 9920-15616=-5696. Assuming the preset value is 0, the second indication information can be generated, indicating moving in the opposite direction of the current target moving direction, that is, moving to the left. .
