Description

[Technical field]

[0001] This application is filed based on a Chinese patent application with application number 202111144004.3 and filing date September 28, 2021, and claims priority to the Chinese patent application, the entire contents of which are hereby incorporated by reference into this application.

[0002] The embodiments of the present application relate to the technical field of Internet, and in particular to a data processing method, system, terminal, and computer-readable storage medium. [Background technology]

[0003] With the rapid development of communication technology, the application of Near Field Communication (NFC) technology is gradually increasing. NFC is a short-range high-frequency wireless communication technology that enables easy and secure two-way communication between multiple electronic devices. NFC technology is an evolution of the integration of contactless RF identification technology (RFID) and interconnection technology, realizing induction card reader, induction card, and point-to-point communication on a single chip, enabling identification and data exchange with compatible devices within a short distance.

[0004] Terminals that support NFC technology have the ability to simulate a physical RF card, that is, the terminal itself is simulated as a physical RF card, such as an access control card, bank card, bus card, etc., and users only need to bring the terminal simulated as a physical RF card close to a card reader, enter the password to confirm the transaction, or swipe the card directly to perform the transaction.

[0005] However, terminals that support NFC technology have many limitations in simulating physical RF cards. For example, telecommunications carriers and manufacturers that sell point of sales terminals (POS terminals) do not allow terminals that support NFC technology to simulate physical RF cards, and terminals cannot simulate physical RF cards. Terminal owners have no choice but to use physical RF cards to consume, but in the case of physical RF cards, there is a certain delay in data processing, and users cannot query consumption records in real time through the terminal, especially the consumption of the elderly and children cannot be monitored in real time.

[0012] In order to clarify the purpose, technical solution and advantages of the embodiments of the present application, various embodiments of the present application will be described in detail below with reference to the drawings. However, although many technical details are provided in various embodiments of the present application to allow the reader to better understand the present application, the technical solution claimed for protection of the present application can be realized without these technical details and various changes and modifications based on the following embodiments. The division of the various embodiments below is made for the convenience of explanation and does not constitute any limitation on the specific embodiment of the present application, and various embodiments can be combined with or referenced to each other unless inconsistent.

[0013] An embodiment of the present application relates to a data processing method applied to a terminal. Hereinafter, the implementation details of the data processing method of the present application will be described in detail, but the following contents are merely implementation details provided for ease of understanding and are not essential for implementing the present application.

[0014] The terminal of the embodiment of the present application may be a mobile phone, a tablet computer, a smart watch, smart glasses, a smart bracelet, etc. that supports the NFC function. This embodiment and the following various embodiments will be described by taking a smartphone that supports the NFC function as an example.

[0015] A specific flow of the data processing method of this embodiment may include steps 101 to 103, as shown in FIG.

[0016] Step 101: Detect whether a first terminal with an NFC function turned on enters an RF field.

[0017] Step 102: When the first terminal enters the RF field and leaves the RF field within a preset time, read the consumption record of the RF card.

[0018] In one embodiment, the first terminal always has the NFC function turned on, and detects whether the first terminal enters the RF field at any time, and reads the consumption record of the RF card when the first terminal enters the RF field and leaves the RF field within a preset time. Here, the preset time may be set by those skilled in the art according to actual needs, but the embodiment of the present application is not particularly limited thereto.

[0019] In one exemplary embodiment, the first terminal is provided with an RF card, the RF card provided in the first terminal is a physical RF card, a card slot is provided on the back side or outside of the rear case of the first terminal, the card slot is configured to fix the physical RF card, the position of the card slot is generally near the NFC antenna of the first terminal, and the physical RF card may be a subway card, a bus card, a campus card, etc., although the embodiment of the present application is not particularly limited thereto.

[0020] In one example, as shown in FIG. 2, FIG. 2 is a side view of a first terminal when a card slot is provided on the back side of a rear case of the first terminal, and the position of the card slot corresponds to the position of the NFC antenna.

[0021] In one example, as shown in Figures 3 and 4, Figure 3 is a side view of a first terminal when a card slot is provided on the outside of the rear case of the first terminal, and Figure 4 is a rear view of the first terminal when the card slot is provided on the outside of the rear case of the first terminal, the position of the card slot corresponds to the position of the NFC antenna, and an RF card is fixed in the card slot.

[0022] In one example, the outside of the rear case of the first terminal may be provided with a card back clip configured to secure an RF card at a position corresponding to the position of the NFC antenna.

[0023] In one exemplary embodiment, when the RF card is in the RF field, consumption can be made through the RF field, but the real RF field may be generated by devices such as subway gates, bus card readers, and POS terminals, or may be transmitted by a wireless charger based on RF charging technology. The RF card can make consumption in the RF field generated by devices such as subway gates, bus card readers, and POS terminals, but cannot make consumption in the RF field transmitted by a wireless charger. Therefore, in this embodiment, after the first terminal enters the RF field, it needs to determine whether it will leave the RF field within a preset time. The preset time may be set to a short time such as 10 seconds, and when the first terminal confirms that it enters the RF field and leaves the RF field within 10 seconds, it is considered that the RF field is generated by devices such as subway gates, bus card readers, and POS terminals, and consumption has occurred on the RF card. The first terminal can more accurately determine whether consumption has occurred on the RF card by reading the consumption record of the RF card, thereby better meeting the actual needs of the user.

[0024] In one exemplary embodiment, if the first terminal does not detect that it has entered the RF field, it may continue to detect until it detects that it has entered the RF field.

[0025] In one example, the first terminal may detect whether the first terminal has entered the RF field by an identification message. Here, the identification message includes at least an RF_FIELD_INFO_NTF message in a Near Field Communication Control Interface Layer (NFC Controller Interface, abbreviated as NCI layer) protocol. When the first terminal enters the RF field, the first terminal can detect whether the first terminal has left the RF field within a preset time by an identification message such as an RF_FIELD_INFO_NTF message, which is a standard message explicitly defined in the NCI layer protocol. The RF_FIELD_INFO_NTF message can be used to more accurately and reliably detect whether the first terminal has entered or left the RF field.

[0026] Step 103: Send the consumption record to a second terminal.

[0027] In one embodiment, after reading the consumption record of the RF card, the first terminal may transmit the acquired consumption record of the RF card to the second terminal for viewing by the second terminal.

[0028] In one example, after the first terminal obtains the consumption record of the RF card, the first terminal may send the obtained consumption record of the RF card to the second terminal in the form of a short message for the second terminal to view based on the telephone number of the second terminal.

[0029] In one example, after the first terminal obtains the consumption record of the RF card, it may notify a pre-developed consumption query application, and the consumption query application may send the obtained consumption record of the RF card to the registered second terminal in the form of an in-application short message.

[0030] In one exemplary embodiment, after the first terminal transmits the consumption record to the second terminal, it may start monitoring anew to continue to detect whether it has entered the RF field.

[0031] In the data processing method, system, terminal, and computer-readable storage medium of the present application, a first terminal has an NFC function turned on and is equipped with an RF card that can be consumed through an RF field, and the first terminal can detect in real time whether it has entered the RF field, and when it detects that it has entered the RF field and left the RF field within a predetermined time, it reads the equipped RF card and obtains the consumption record of the RF card, and after reading the consumption record of the RF card, the first terminal may transmit the consumption record of the RF card to the second terminal for viewing by the second terminal. If the first terminal cannot simulate an RF card, the owner of the first terminal can only use the RF card to consume, and in this case, there is a delay in data processing, i.e., updating the consumption record, so that the owner of the second terminal cannot monitor the consumption of the owner of the first terminal in real time. In consideration of this, in this embodiment, the first terminal is provided with an RF card, and when the first terminal detects that it has entered an RF field and left the RF field within a preset time, it determines that a consumption event has occurred, and in this case, reads the RF card, obtains the consumption record of the RF card, and transmits it to the second terminal in real time. This meets the user's demand for real-time monitoring of the consumption of the owner of the first terminal, such as the elderly and children, and improves the user's usage experience.

[0032] Another embodiment of the present application relates to a data processing method. Hereinafter, the details of the implementation of the data processing method of this embodiment will be specifically described. The following contents are merely implementation details provided for easy understanding, and are not essential to implementing this embodiment. Figure 5 is a flowchart of the data processing method described in this embodiment, including steps 201 to 204.

[0033] Step 201: Detect whether a first terminal that has the NFC function turned on but does not have the card reading function of the NFC function turned on enters the RF field.

[0034] Step 202: When the first terminal enters the RF field and leaves the RF field within a preset time, turn on the card reading function.

[0035] In one embodiment, the first terminal keeps the NFC function turned on, but does not turn on the card reading function of the NFC function until it leaves the RF field, and turns on the card reading function of the NFC function only when the first terminal confirms that it has entered the RF field and left the RF field within a preset time.

[0036] In one exemplary embodiment, considering that the first terminal also generates an RF field after turning on the card reading function of the NFC function, when the first terminal enters the RF field generated by devices such as subway gates, bus card readers, and POS terminals, the RF card installed in the first terminal will enter two RF fields at the same time. As a result, not only will the first terminal be unable to read the RF card, but the consumption of the RF card may also fail. Therefore, in this embodiment, the NFC function is subdivided, and the card reading function of the NFC function is turned on only when the first terminal leaves the RF field, thereby ensuring that the RF card only enters one RF field at the same time, and avoiding the consumption of the RF card being interfered with and failing.

[0037] Step 203: Read the consumption record of the RF card. Here, step 203 is substantially the same as step 102 and will not be further discussed here.

[0038] Step 204: Send the consumption record to a second terminal.

[0039] In one exemplary embodiment, the first terminal may turn off the card reading function of the NFC function after transmitting the consumption record to the second terminal, thereby ensuring that the first terminal does not generate an RF field, and ensuring that the next time the first terminal enters an RF field, the RF card only enters an RF field generated by devices such as subway gates, bus card readers, and POS terminals, and ensuring that the RF card can smoothly perform consumption.

[0040] In this embodiment, the first terminal does not turn on the card reading function of the NFC function before leaving the RF field, and when the first terminal enters the RF field and leaves the RF field within a preset time, the step of reading the consumption record of the RF card includes the steps of turning on the card reading function when the first terminal enters the RF field and leaves the RF field within a preset time, and reading the consumption record of the RF card. The first terminal does not turn on the card reading function by default, and only when the first terminal detects that it has entered the RF field and left the RF field within a preset time, does it turn on the card reading function and read the consumption record of the RF card. This can effectively prevent the RF field of the first terminal from interfering with the consumption of the RF card, and ensure that the consumption of the RF card is normal.

[0041] In another embodiment, the owner of the second terminal may monitor the location of the owner of the first terminal in real time by the steps shown in FIG. 6, which specifically include steps 301 to 302.

[0042] Step 301: Obtain location information of a first terminal.

[0043] Step 302: The location information of the first terminal is sent to the second terminal together with the consumption record.

[0044] In one embodiment, after reading the consumption record of the RF card, the first terminal may turn on a positioning function, obtain the real-time location of the first terminal, generate location information of the first terminal, and send the location information of the first terminal together with the consumption record to the second terminal for viewing by the second terminal.

[0045] In one exemplary embodiment, the user is not only interested in the consumption of the elderly and children, but also interested in where the elderly and children consume. For example, the first terminal is owned by a student, and one of its consumption records is the purchase of instant noodles, and the importance to the user is obviously different between the consumption record that occurred at the school supermarket and the consumption record that occurred at the Internet cafe. Therefore, in this embodiment, after obtaining the consumption record, the first terminal obtains its own location in real time, and transmits the location information of the first terminal together with the consumption record to the second terminal, so that the user can monitor where the owner of the first terminal consumes, thereby better meeting the usage needs of the user.

[0046] In one example, the first terminal may include the location information of the first terminal in the consumption record after obtaining the location information of the first terminal. The first terminal transmits the consumption record to the second terminal for the second terminal to view, i.e., transmits the location information of the first terminal to the second terminal for the second terminal to view. In some cases, the consumption record of the RF card itself includes the location information. For example, in the case of subway ride consumption, the consumption record may show that the first terminal gets off at station A and gets off at station B, in which case the location information of the first terminal is included in the consumption record, and the first terminal only needs to transmit the consumption record to the second terminal. This reduces the amount of data interaction and better meets the usage needs of users.

[0047] Another embodiment of the present application relates to a data processing method. Hereinafter, the details of the implementation of the data processing method of this embodiment will be specifically described. The following contents are merely implementation details provided for easy understanding, and are not essential to implementing this embodiment. Figure 7 is a flowchart of the data processing method described in this embodiment, including steps 401 to 405.

[0048] Step 401: Detect whether a first terminal with an NFC function turned on enters an RF field.

[0049] Here, step 401 is substantially the same as step 101 and will not be further discussed here.

[0050] Step 402: When a first terminal enters the RF field and leaves the RF field within a preset time, read the balance information of the RF card.

[0051] In one embodiment, when the first terminal detects that it has entered an RF field and left the RF field within a preset time, it may read balance information of the RF card, where the balance information may represent a monetary value remaining on the RF card.

[0052] Step 403: It is determined whether the currently acquired balance information is the same as the previously acquired balance information. If they are the same, the process returns to step 401; if they are not the same, step 404 is executed.

[0053] Step 404: Obtain the consumption record of the RF card.

[0054] In one exemplary embodiment, after obtaining the balance information of the RF card, the first terminal may determine whether the currently obtained balance information is the same as the previously obtained balance information. If the currently obtained balance information is different from the previously obtained balance information, it indicates that consumption has been made on the RF card, and the first terminal may obtain a consumption record of the RF card.

[0055] In one example, the first terminal determines that the currently acquired balance information is the same as the previously acquired balance information, which indicates that the RF card has entered the RF field but no consumption has occurred. In this case, the first terminal does not need to acquire a consumption record, and may end the current consumption query and perform the next monitoring to continue detecting whether the first terminal has entered the RF field.

[0056] Step 405: Send the consumption record to a second terminal. Here, step 405 is substantially the same as step 103 and will not be further discussed here.

[0057] In this embodiment, the step of reading the consumption record of the RF card includes the steps of reading the RF card and obtaining the balance information of the RF card; if the balance information is the same as the previously obtained balance information, determining that the RF card has not been consumed and re-detecting whether the first terminal has entered the RF field; and if the balance information is different from the previously obtained balance information, obtaining the consumption record of the RF card. When the first terminal detects that it has entered the RF field and left the RF field within a preset time, it further detects whether the balance of the RF card has changed. If the balance has not changed, it indicates that no consumption has been made on the RF card, and the first terminal re-detects whether the first terminal has entered the RF field. If the balance has changed, it indicates that consumption has been made on the RF card, and the first terminal obtains the consumption record of the RF card. Thereby, it can effectively prevent the first terminal from sending a useless empty consumption record to the second terminal, reduce unnecessary information exchange, and save communication resources.

[0058] Another embodiment of the present application relates to a data processing method. The details of the implementation of the data processing method of this embodiment will be specifically described below. The following contents are merely implementation details provided for easy understanding and are not essential to implement this embodiment. Figure 8 is a flowchart of the data processing method described in this embodiment, including steps 501 to 506.

[0059] Step 501: Detect whether a first terminal that has the NFC function turned on but does not have the card reading function of the NFC function turned on enters the RF field.

[0060] Step 502: When the first terminal enters the RF field and leaves the RF field within a preset time, turn on the card reading function.

[0061] Step 503: Read the balance information of the RF card.

[0062] Step 504: Determine whether the currently acquired balance information is the same as the previously acquired balance information. If they are the same, return to step 501 to continue detection; if they are different, execute step 505.

[0063] Step 505: Obtain the consumption record of the RF card.

[0064] Step 506: Send the consumption record to a second terminal.

[0065] Another embodiment of the present application relates to a data processing system. The details of the data processing system of this embodiment will be specifically described below.

Figure 9 is a schematic diagram of the data processing system described in this embodiment, including a first terminal 601, an RF card 602 provided in the first terminal 601, and a second terminal 603.

[0066] The first terminal 601 is configured to detect whether the first terminal 601 has entered an RF field, and if the first terminal 601 has entered the RF field and left the RF field within a preset time, to read the consumption record of the RF card 602 and transmit the consumption record to the second terminal 603.

[0067] The RF card 602 is configured to consume through the RF field if the first terminal 601 enters the RF field and leaves the RF field within a pre-set time.

[0068] The second terminal 603 is configured to receive the consumption record sent by the first terminal 601 .

[0069] It should be noted that this embodiment is a system embodiment corresponding to the above method embodiment, and this embodiment may be implemented in cooperation with the above method embodiment. The relevant technical details and technical effects described in the above embodiment are also valid in this embodiment, so they will not be further mentioned here in order to reduce duplication. Therefore, the technical details described in this embodiment may also be applied to the above embodiment.

[0070] In addition, each module according to the present embodiment is a logical module, and in reality, one logical unit may be one physical unit, may be a part of one physical unit, or may be realized by a combination of multiple physical units. Furthermore, in order to emphasize the innovative part of the present application, units that are not very related to solving the technical problem of the present application are not introduced in this embodiment, but this does not mean that other units do not exist in this embodiment.

[0071] Another embodiment of the present application relates to a terminal, as shown in Fig. 10. The terminal includes at least one processor 701 and a memory 702 communicatively connected to the at least one processor 701, the memory 702 storing instructions executable by the at least one processor 701, which, when executed by the at least one processor 701, cause the at least one processor 701 to perform the data processing method in the above embodiment.

[0072] Here, the memory and the processor are connected in a bus manner, which may include any number of interconnected buses or bridges, and the bus connects together one or more processors and various circuits of the memory. The bus may also connect together various other circuits, such as peripherals, regulators, power management circuits, etc., all of which are known to those skilled in the art and will not be described further herein. The bus interface provides an interface between the bus and the transceiver. The transceiver may be one unit or multiple units, such as multiple receivers and transmitters, providing the unit for communicating with various other devices over a transmission medium. The data processed by the processor is transmitted over a wireless medium via an antenna, which further receives the data and transmits the data to the processor.

[0073] The processor is responsible for managing the bus and general processing and may provide a variety of functions including timing, peripheral interfaces, voltage regulation, power management, and other control functions, while memory may be used to store data used by the processor in performing operations.

In the case where the first terminal cannot simulate an RF card, the owner of the first terminal can only use the RF card to consume, and in this case, there is a delay in data processing, i.e., updating the consumption record, so that the owner of the second terminal cannot monitor the consumption of the owner of the first terminal in real time. In view of this, in this embodiment, the first terminal is provided with an RF card, and when the first terminal detects that the first terminal has entered the RF field and left the RF field within a preset time, the first terminal determines that a consumption event has occurred, and in this case, reads the consumption record of the RF card and transmits it to the second terminal in real time. This meets users' demands for real-time monitoring of consumption by primary device owners, such as the elderly and children, and improves users' usage experience.
