However, most business users in the consumer market do not support access to the use of virtual radio frequency cards, and real radio frequency cards are still the main payment tools. Therefore, when a ward (e.g., a child) uses a real radio frequency card to make consumption payments, the guardian cannot timely obtain the consumption data of the real radio frequency card, which is disadvantageous to the guardian's consumption supervision and management.

[0010] It is understood that the specific examples described herein are used only to illustrate the present disclosure and are not used to limit the present disclosure.

[0011] In the following description, suffixes such as "module", "part", or "unit" used to represent components are used only to facilitate the description of the present disclosure and do not have any special meaning in themselves. Therefore, "module", "part", or "unit" may be used interchangeably.

[0012] The Near Field Communication (NFC) technology provided by the embodiments of the present disclosure has an operating frequency of 13.56 MHz and is a short-range, high-frequency wireless communication technology that enables contactless point-to-point data transmission between electronic devices, with a communication distance of 0-20 cm (in practice, most products are within 10 cm), and supports one or more protocols of Type A, Type B, and Type F.

[0013] In an embodiment of the present disclosure, a terminal device is provided, the terminal device includes a detection circuit and a built-in NFC unit. A physical radio frequency card is provided in the housing of the terminal device. The detection circuit detects a first radio frequency signal. The built-in NFC unit transmits a second radio frequency signal to the physical radio frequency card. The terminal device further controls the built-in NFC unit to transmit a second radio frequency signal to the physical radio frequency card in response to the first radio frequency signal, thereby obtaining transaction data of the physical radio frequency card.

[0014] The present disclosure is applicable to the case where there are consumption POS devices (Point Of Sale, sales terminals) such as buses, subway stations, and beverage vending machines. The POS devices (sales terminals) and the terminal devices can perform data interaction through NFC technology. The terminal devices also need to support short message or data services. The physical radio frequency card can be a bus card, a work card, a bank card, etc., and the main body of the terminal device can be a mobile terminal, which includes electronic devices such as mobile phones, tablets, laptops, desktop computers, personal digital assistants, and wearable devices.

[0015] In the current application of NFC technology, users spend using real radio frequency cards or virtual radio frequency cards simulated by NFC in mobile phones. Although NFC technology has been added to mobile phones for nearly 10 years, it is still not practically usable due to many non-technical reasons. For example, compatibility issues between mobile phone radio frequency NFC antennas and POS machine antennas, and the use of virtual radio frequency cards requires access to the use of business users, and mobile phone manufacturers or operators need to complete debugging work with business users' POS machines before spending using virtual radio frequency cards. In the case where most business users do not support access to the use of virtual radio frequency cards, real radio frequency cards have become the main payment tool. However, transaction data generated by wards such as children and the elderly using real radio frequency cards cannot be transmitted to the guardian in real time, which is disadvantageous for the guardian to track and supervise the consumption behavior of the ward. In addition, the transaction data includes the payment amount, payment time, consumption type, and business name.

[0016] On this basis, the terminal device provided by the present disclosure combines a physical radio frequency card, a detection circuit and a built-in NFC unit to realize real-time supervision and management of transaction data of the physical radio frequency card.

[0017] 1, an embodiment of the present disclosure provides a terminal device 100. The terminal device 100 includes a housing 101, a card slot 102, and a physical radio frequency card 103. The card slot 102 is provided in the housing 101, and may be configured to accommodate the physical radio frequency card 103.

[0018] The card slot 102 may be provided inside the housing 101 or outside the housing 101. The fixing method for placing the physical radio frequency card 103 in the card slot 102 includes any suitable method, such as clamping, gluing, or welding.

[0019] When the card slot 102 is provided outside the housing 101, the card slot 102 may be a groove on the visible outer surface of the housing 101. The card slot 102 may be a strap of the terminal equipment 100, and the strap may be used together with a rope chain. The card slot 102 may be provided in the protective case of the terminal equipment 100. In some examples, the card slot 102 may be a gap between the terminal equipment 100 and the protective case, the purpose of which is to ensure that the distance between the real radio frequency card 103 and the housing 101 is sufficiently close, so as to ensure that the strength of the first radio frequency signal received by the real radio frequency card 103 and the strength of the first radio frequency signal received by the terminal equipment 100 are essentially the same, thereby ensuring that the terminal equipment 100 can accurately determine whether the real radio frequency card 103 has entered an external radio frequency field.

[0020] When the card slot 102 is provided inside the housing 101, the card slot 102 may be a groove on an invisible inner surface of the housing 101. The card slot 102 may be a fitting groove on a circuit board of the terminal device 100. In some examples, the fitting opening of the card slot 102 is on an invisible outer surface of the housing 101, and the physical radio frequency card 103 may be fitted inside the housing 101 through the fitting opening.

[0021] In addition, the physical radio frequency card 103 may be a card that enables a transaction, such as a bus card, a work card, or a bank card, and the protective case may be a decorative item that protects or decorates the appearance of the terminal device 100.

[0022] In some exemplary embodiments, the terminal device 100 may further include a detection circuit and a built-in NFC unit.

[0023] The detection circuit and the built-in NFC unit may be provided inside the terminal device 100 surrounded by the housing 101. The terminal device 100 uses the detection circuit to determine whether the physical radio frequency card 103 on the terminal device 100 enters an external radio frequency field. The external radio frequency field is a radio frequency field generated by a sales terminal. When a user uses the physical radio frequency card 103 to consume, the physical radio frequency card 103 enters the external radio frequency field, and the terminal device 100 turns off the NFC function of the mobile phone to prevent interference with the transaction process. Based on this, it is guaranteed that the physical radio frequency card 103 can transmit data stably when interacting with the sales terminal, and the user can make a normal card payment. When the physical radio frequency card 103 is removed from the external radio frequency field, the terminal device 100 can automatically turn on the built-in NFC unit of the mobile phone to read the transaction data of the physical radio frequency card 103 and send it to the target user by a method such as a shot message, ensuring that the target user can instantly know the status of the monitored physical radio frequency card 103 without long delay.

[0024] 2, the present disclosure provides a detection circuit 300. The detection circuit 300 includes a combining circuit 301, an acquiring circuit 302, and a processing unit 303.

[0025] The operation principle of the coupling circuit 301 is the inductive coupling principle, in which the coupling circuit 301 detects a first radio frequency signal and converts the magnetic field energy of the external radio frequency field into electric energy. The coupling circuit 301 includes an induction coil. The induction coil may be an antenna of the built-in NFC unit in the terminal device 100, or may be an independently installed coil. When the induction coil and the built-in NFC unit share the same antenna, when the built-in NFC unit is off, the antenna is used as a part of the coupling circuit 301, and when the built-in NFC unit is on, the antenna is also used as the antenna of the built-in NFC unit.

[0026] For example, the physical radio frequency card 103 may be a bank card, and the external radio frequency field may be generated by a POS machine. When the bank card enters the external radio frequency field, both the bank card and the coupling circuit 301 may receive a first radio frequency signal, and the coupling circuit 301 converts the first radio frequency signal into an induced electric signal, such as a current signal or a voltage signal, and the terminal equipment 100 may determine whether the bank card has performed a card payment operation according to the induced electric signal. In order to prevent false alarms, the terminal equipment 100 may determine whether the bank card has performed a card payment operation according to whether the voltage amplitude or current size generated on the coil reaches a set threshold, and because the radio frequency NFC card may generate a persistent magnetic field energy when performing a card payment, the terminal equipment 100 may further determine whether the bank card has performed a card payment operation according to the length of time generated by the induced voltage or current.

[0027] The induced electrical signal collected by the induction coil is usually a weak signal with noise and cannot be directly observed and analyzed, so the induced electrical signal needs to be rectified, filtered, amplified and other signal shaping to remove the noise in the signal, so as to make it into a characteristic electrical signal in a stable state. The characteristic electrical signal can record the characteristic information of the first radio frequency signal and reflect the change rule of the first radio frequency signal.

[0028] The acquisition circuit 302 converts the induced signal into a feature electrical signal and sends the feature electrical signal to the processing unit 303. The acquisition circuit 302 obtains the induced electrical signal generated by the coupling circuit 301, and performs signal shaping on the induced electrical signal by an amplifier, a filter, etc., and a transistor circuit, etc. For example, the feature electrical signal is generated by removing noise from the induced electrical signal by a filter and providing excitation to the induced electrical signal by an amplifier. The feature electrical signal after signal shaping can be analyzed by the processing unit 303. Finally, the acquisition circuit 302 transmits the feature electrical signal to the processing unit 303.

[0029] The processing unit 303 analyzes the characteristic electrical signal and obtains the characteristic information of the first radio frequency signal to determine whether the terminal device 100 has entered an external radio frequency field. The processing unit 303 may be an application processor (AP) of the terminal device 100, or another processor of the terminal device 100.

[0030] Taking the induced electrical signal as an example of voltage, when a user consumes through the physical radio frequency card 103 of the terminal equipment 100, the terminal equipment 100 enters the external radio frequency field, the coupling circuit 301 generates an induced voltage, and the induced voltage is converted into a characteristic voltage through the sampling circuit, but when the consumption of the physical radio frequency card 103 is completed, the induced voltage disappears. The closer the distance between the terminal equipment 100 and the vending terminal, the larger the induced voltage becomes. When the terminal equipment 100 and the vending terminal reach a set distance, the physical radio frequency card 103 on the housing 101 of the terminal equipment 100 may realize payment of consumption by data interaction with the vending terminal. The induced voltage in this case is set as a reference value, and if the acquired induced voltage is equal to or greater than the reference value, it is deemed that the physical radio frequency card 103 has entered the external radio frequency field of the vending terminal. Thus, the processor may determine whether the physical radio frequency card 103 has entered or exited the external radio frequency field according to the height of the characteristic voltage.

[0031] In other embodiments, the processor may further perform processing analysis on the induced electrical signal, such as a current signal or an interruption signal. Because the physical radio frequency card 103 generates a continuous magnetic field energy when performing a card transaction, the processor may further use the length of time generated by the induced voltage or current as a criterion. The processor may determine whether the terminal device 100 has entered or exited the radio frequency field in response to any one or more induced electrical signals.

[0032] The processing unit 303 determines whether the physical radio frequency card 103 enters or exits the external radio frequency field according to the characteristic electrical signal. When the physical radio frequency card 103 enters the external radio frequency field to make a consumption payment, the characteristic electrical signal received by the processing unit 303 is equal to or greater than the set intensity, and the built-in NFC unit of the terminal equipment 100 should be turned off to prevent interference with the consumption payment between the physical radio frequency card 103 and the POS machine. After the physical radio frequency card 103 leaves the external radio frequency field, the characteristic electrical signal received by the processing unit 303 changes from equal to or greater than the set intensity to less than the set intensity, and the built-in NFC unit of the terminal equipment 100 should be started to timely read the transaction data of the physical radio frequency card 103. For example, after a 1-second interval after recognizing that the physical radio frequency card 103 has left the external radio frequency field, the built-in NFC unit is started to read the transaction data of the physical radio frequency card 103 by sending a second radio frequency signal to the physical radio frequency card. Here, the interval time may be set artificially.

[0033] The built-in NFC unit transmits a second radio frequency signal to the physical radio frequency card 103, causing the physical radio frequency card 103 to return transaction data, and further obtains the transaction data returned from the physical radio frequency card 103, and transmits the transaction data to the application processor of the terminal device 100.

[0034] The terminal device 100 further includes a mobile phone side application program. When the application program is installed in the terminal device 100, it is necessary to grant the corresponding authority to the terminal device 100. For example, the authority of the current location information, the user's mobile phone number, the account of the instant messaging software, and the network information may be obtained.

[0035] Through the application, the terminal device 100 may generate notification information according to the transaction data and related information, and send the notification information to the target user, for example, by generating the notification information according to the transaction data and current location information.

[0036] Based on this, the terminal device 100 provided in the embodiment of the present disclosure can obtain transaction data generated when the ward uses the physical radio frequency card 103 to consume in real time, and send the transaction data to the guardian, thereby solving the problems of poor timeliness and incomplete message notification of the physical radio frequency card 103, and thereby improving the guardian's ability to supervise and manage consumption.

[0037] As shown in Fig. 3, in this embodiment, a data processing method is provided, which is applied to the above terminal device. The steps of the method may include the following operations: S101 to S103.

[0038] S101, acquiring a first radio frequency signal of a sales terminal.

[0039] In the current application of NFC technology, users spend using real radio frequency cards or virtual radio frequency cards simulated by NFC in mobile phones. Although NFC technology has been added to mobile phones for nearly 10 years, it is still not practically usable due to many non-technical reasons. For example, compatibility issues between mobile phone radio frequency NFC antennas and POS (Point Of Sale) machine antennas, and the use of virtual radio frequency cards requires access to the use of business users, and mobile phone manufacturers or operators need to complete debugging work with business users' POS machines before spending using virtual radio frequency cards. In the case where most business users do not support access to the use of virtual radio frequency cards, real radio frequency cards have become the main payment tool. However, transaction data generated by wards such as children and the elderly using real radio frequency cards cannot be transmitted to the guardian in real time, which is disadvantageous for the guardian to track and supervise the consumption behavior of the ward. In addition, the transaction data includes the payment amount, payment time, consumption type, and business name.

[0040] On this basis, the data processing method provided by the present disclosure realizes real-time supervision and management of transaction data of a physical radio frequency card through a physical radio frequency card, a detection circuit, and a built-in NFC unit on a terminal device.

[0041] The terminal device includes a physical radio frequency card, a detection circuit, and a built-in NFC unit. The detection circuit includes a coupling circuit, a collection circuit, and a processing unit. The physical radio frequency card is placed in a location such as a housing that is sufficiently close to the mobile phone, thereby ensuring that the strength of the first radio frequency signal received by the physical radio frequency card and the strength of the first radio frequency signal received by the mobile phone are essentially the same. The terminal device may be a mobile phone, and when the physical radio frequency card enters the external radio frequency field generated by the sales terminal, it obtains the first radio frequency signal output by the POS machine through an induction coil on the coupling circuit on the mobile phone.

[0042] The operation principle of the coupling circuit is the inductive coupling principle, and the coupling circuit may detect a first radio frequency signal and convert the magnetic field energy of the external radio frequency field into electrical energy. The coupling circuit includes an induction coil. The induction coil may be an antenna of the built-in NFC unit in the terminal device, or may be an independently installed coil. If the induction coil and the built-in NFC unit share the same antenna, when the built-in NFC unit is off, the antenna is used as part of the coupling circuit, and when the built-in NFC unit is on, the antenna is also used as the antenna of the built-in NFC unit.

[0043] The physical radio frequency card may be a bank card, and the external radio frequency field may be generated by a POS machine. When the bank card enters the external radio frequency field, both the bank card and the coupling circuit can receive a first radio frequency signal, and the physical radio frequency card completes a transaction with the sales terminal in the external radio frequency field, and the coupling circuit converts the first radio frequency signal into an induced electrical signal, such as a current signal or a voltage signal. The terminal device may determine whether the bank card has performed a card payment operation according to the induced electrical signal.

[0044] The induced electrical signal collected by the induction coil of the coupling circuit is usually a weak signal with noise and cannot be directly observed and analyzed, so the induced electrical signal needs to be rectified, filtered, amplified and other signal shaping to remove the noise in the signal, so as to make it into a characteristic electrical signal in a stable state. The characteristic electrical signal can record the characteristic information of the first radio frequency signal and reflect the change rule of the first radio frequency signal.

[0045] It should be noted that the physical radio frequency card may be a bus card, a work card, a bank card, etc., and the main body of the terminal device may be other mobile terminals, including mobile phones, tablets, laptops, desktop computers, personal digital assistants, wearable devices and other electronic devices.

[0046] In this way, the recognition of the external radio frequency field of the physical radio frequency card and the mobile phone can be performed synchronously, so as to realize the acquisition of the transaction status information of the physical radio frequency card in the subsequent process.

[0047] S102, in response to the first radio frequency signal, transmitting a second radio frequency signal to the physical radio frequency card, thereby causing the physical radio frequency card to transmit transaction data.

[0048] To prevent false alarms, the terminal device may determine whether the bank card has performed a card payment operation according to whether the voltage amplitude or current size generated on the coil reaches a set threshold, and because a radio frequency NFC card may generate persistent magnetic field energy when performing a card payment, the terminal device may further determine whether the bank card has performed a card payment operation according to the length of time generated by the induced voltage or current.

[0049] The collecting circuit on the mobile phone converts the induced signal into a characteristic electrical signal and sends the characteristic electrical signal to a processing unit. The collecting circuit obtains the generated induced electrical signal and performs signal shaping on the induced electrical signal by an amplifier, a filter, etc., and a transistor circuit, etc. For example, the filter removes noise from the induced electrical signal, and the amplifier provides excitation to the induced electrical signal. The characteristic electrical signal after signal shaping may be analyzed by the processing unit. Finally, the collecting circuit transmits the characteristic electrical signal to the processing unit.

[0050] The induced electrical signal collected by the induction coil is usually a weak signal with noise and cannot be directly observed and analyzed, so the induced electrical signal needs to be rectified, filtered, amplified and other signal shaping to remove the noise in the signal, so as to make it into a characteristic electrical signal in a stable state. The characteristic electrical signal can record the characteristic information of the first radio frequency signal and reflect the change rule of the first radio frequency signal.

[0051] The acquisition circuit performs signal shaping on the induced electrical signal by amplifiers, filters, etc., and transistor circuits, etc. For example, the filter removes noise from the induced electrical signal, and the amplifier provides excitation to the induced electrical signal. The characteristic electrical signal after signal shaping may be analyzed by a processing unit. Finally, the acquisition circuit transmits the characteristic electrical signal to the processing unit.

[0052] The characteristic electrical signal is analyzed by a processing unit to obtain the characteristic information of the first radio frequency signal, thereby determining whether the terminal device has entered the radio frequency field. The processing unit may be an Application Processor (AP) of the terminal device, or another processor of the terminal device.

[0053] The closer the distance between the terminal device and the sales terminal, the greater the signal strength of the first radio frequency signal received by the terminal device. When the signal strength of the first radio frequency signal received by the physical radio frequency card reaches a set value, the physical radio frequency card may be deemed to have completed a payment at the sales terminal. Thus, when the terminal device detects that the first radio frequency signal is equal to or greater than the set strength, it turns off the built-in NFC unit, thereby preventing the internal radio frequency field generated by the built-in NFC unit from interfering with the transaction process. After the first radio frequency signal is converted, an induced electric signal is obtained, and the induced electric signal is amplified by the collection circuit to obtain a characteristic electric signal, so that the signal strength of the first radio frequency signal may be obtained by conversion. When the processing unit detects that the first radio frequency signal is less than the set strength, it turns on the built-in NFC unit, and transmits a second radio frequency signal to the physical radio frequency card via the built-in NFC unit.

[0054] Take the induced electrical signal as voltage for example, when the user consumes through the real radio frequency card of the terminal device, the terminal device enters the external radio frequency field, the coupling circuit generates an induced voltage, and the induced voltage is converted into a characteristic voltage through the sampling circuit, but when the consumption of the real radio frequency card is completed, the induced voltage disappears.Therefore, the processor can determine whether the real radio frequency card enters or leaves the external radio frequency field according to the height of the characteristic voltage.

[0055] In other embodiments, the induced electrical signal may be a current signal or a voltage interruption signal. Because the real radio frequency card generates a continuous magnetic field energy when making a card payment, the determination criterion may further depend on the duration of the induced voltage or current. The processor may determine whether the terminal device enters or exits the radio frequency field according to any one or more methods.

[0056] In the embodiment, when the bank card is close to the POS machine to make a consumption payment, the built-in NFC unit of the terminal device should be turned off to prevent interference with the consumption payment between the bank card and the POS machine.After the physical radio frequency card leaves the external radio frequency field, the built-in NFC unit of the terminal device should be automatically turned on to timely read the transaction data of the physical radio frequency card.

[0057] The built-in NFC unit transmits a second radio frequency signal to the physical radio frequency card, causing the physical radio frequency card to return transaction data, obtains the transaction data returned from the physical radio frequency card, and transmits the transaction data to the application processor of the terminal device.

[0058] In this way, the consumption supervision and management and consumption data processing of the physical radio frequency card are realized without interfering with the consumption of the physical radio frequency card.

[0059] S103, acquire transaction data.

[0060] The terminal device further includes a mobile phone side application program. When the application program is installed in the terminal device, it is necessary to grant the terminal device corresponding authority. For example, the authority of the current location information, the user's mobile phone number, the account of the instant messaging software, and the network information may be obtained.

[0061] The application program is used to generate notification information according to the transaction data and the current location information, and send the notification information to the target user.

[0062] The present disclosure further provides a flowchart of an application example of the data processing method, as shown in Figure 4. The steps of the application example include S201 to S206.

[0063] S201, turn on the mobile phone.

[0064] S202, turn off the built-in NFC unit on your phone.

[0065] S203, the detection circuit detects whether the mobile phone enters or exits the external radio frequency field; if it is detected that the mobile phone enters the external radio frequency field, proceed to step S204;

[0066] S204, turn on the built-in NFC unit, enter into a card reading mode, and obtain transaction data from the physical radio frequency card.

[0067] S205, obtaining transaction data and location data through an application program.

[0068] S206, the transaction data and the location data are sent to the target user in the form of message or data through the application program, and after the sending is completed, return to step S202.

[0069] Based on the data processing method provided by the embodiment of the present disclosure, the problem of the real radio frequency card's message notification being untimely and incomplete can be solved, and the problem of the virtual radio frequency card being unusable due to non-technical reasons can also be solved. When the ward uses the terminal device, the guardian can instantly know the ward's consumption status and current location address, so as to supervise and manage the ward's transactions in a timely manner.

[0070] As shown in Fig. 5, in an embodiment of the present disclosure, a data processing device 20 is provided. The device 20 includes a memory 21, a processor 22, a program stored in the memory and executable on the processor, and a data bus 23 for realizing a connection communication between the processor 21 and the memory 22. When the program is executed by the processor, the device 20 realizes the steps shown in Fig. 3 below: acquiring a first radio frequency signal, sending a second radio frequency signal to the physical radio frequency card in response to the first radio frequency signal, thereby causing the physical radio frequency card to send transaction data, and acquiring the transaction data.

[0071] In some embodiments, data processing device 20 may also facilitate transmitting the transaction data to the target user.

[0072] In some embodiments, the data processing device 20 may further realize obtaining current location information of the terminal device, and sending the current location information and the transaction data to the target user.

[0073] In some embodiments, the data processing device 20 may further be implemented to turn off the built-in NFC unit upon detecting that the first radio frequency signal is above a set strength.

[0074] In some embodiments, the data processing device 20 may further realize, when detecting that the first radio frequency signal is less than a set strength, turning on the built-in NFC unit and sending a second radio frequency signal to the physical radio frequency card via the built-in NFC unit.

[0075] In an embodiment of the present disclosure, a computer-readable storage medium is provided, which may store one or more programs and may be executed by one or more processors to realize any of the data processing methods provided by the embodiment of the present disclosure.

[0077] Based on the terminal device, data processing method, device and storage medium provided by the embodiments of the present disclosure, the real radio frequency card and the mobile terminal are bound, the consumption data of the real radio frequency card is monitored and obtained through the mobile terminal, and the consumption data and the current location of the mobile terminal are sent to the target user, so that the problem of the real radio frequency card's message notification being untimely and incomplete can be solved, and the problem of the virtual radio frequency card being unusable due to non-technical reasons can also be solved. When the ward uses the terminal device, the guardian can instantly know the ward's consumption situation and the address of the current location, so as to supervise and manage the ward's transactions in a timely manner.

[0078] It will be understood by those skilled in the art that all or some of the steps in the methods, systems, and functional modules / units of the devices disclosed above may be implemented as software, firmware, hardware, or an appropriate combination thereof.
