[0054] 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.

[0055] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0056] In the following description, reference is made to “some embodiments”, which describe a subset of all possible embodiments, but it will be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0057] It should be pointed out that the terms "first\second\third" involved in the embodiments of the present application are merely used to distinguish similar objects and do not represent a specific ordering of the objects. It can be understood that "first\second\third" can be interchanged in a specific order or sequence where permitted, so that the embodiments of the present application described here can be implemented in an order other than that illustrated or described here.

[0058] In the related art, the process of writing numbers for mobile terminals / terminal devices (such as mobile phones) can mainly include three steps: the first step is to manually connect the mobile phone to be written with the writing tool, and the writing tool writes the number for the mobile phone to be written; the second step is to print out an IMEI label with the IMEI number written into the mobile phone by a printer, and manually attach the IMEI label to the mobile phone; the third step is to manually scan the IMEI label attached to the mobile phone, and the writing tool reads the scanned IMEI number and compares it with the IMEI number written into the mobile phone to check whether the number written into the mobile phone is consistent with the number on the IMEI label. However, this traditional method has at least the following problems: the existing process of writing numbers for mobile terminals requires three steps, which takes a long time, and each step requires an operator to perform manual operation, which has a high labor cost.

[0059] In view of the problems existing in the traditional number writing process, some technicians have studied it and proposed certain improvement methods, such as: writing numbers by connecting the number writing fixture to the terminal device through a hardware interface, or writing numbers by sending data through the server in a network manner. Although the relevant technology has made certain improvements to the number writing process of the terminal device, the existing number writing method still has the following defects:

[0060] (1) If the terminal device is required to provide a relevant reserved hardware interface, such as a serial port or a pin port, then a number writing fixture is required to write numbers to each terminal device through the hardware interface connection. It is impossible to complete the number writing function without contacting the terminal device.

[0061] (2) If the number is written by sending data through the server via the network, then the dependence on the network environment is relatively high. At this time, a good network or wireless signal is required to achieve contactless number writing on the terminal device. Once the network or wireless signal is interrupted, the number writing work cannot be carried out.

[0062] Based on this, the embodiment of the present application provides a contactless number writing method, the basic idea of ​​which is: the terminal device and the NFC card establish a connection through NFC communication, wherein the NFC card carries the device information of the terminal device; the terminal device reads the device information carried by the NFC card based on NFC communication; when the device information is read successfully, the device information is stored in the preset cache area of ​​the terminal device. In this way, when writing numbers to the terminal device, the terminal device only needs to establish a connection with the NFC card through NFC communication, and the device information carried by the NFC card can be saved locally in the terminal device to complete the number writing to the terminal device. The number writing process does not require the terminal device to have a hardware interface corresponding to the number writing fixture, and does not rely on the network environment, so that the contactless number writing function can be realized, and there is no requirement for the network environment, which reduces the dependence on the network environment and is convenient and fast.

[0063] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0064] In one embodiment of the present application, see Figure 1 , which shows a schematic flow chart of a contactless number writing method provided by an embodiment of the present application, and the method is applied to a terminal device. Figure 1 As shown, the method may include:

[0065] S101. Establish a connection with an NFC card through NFC communication, wherein the NFC card carries device information of a terminal device.

[0066] It should be noted that the number writing is usually done during the production process of terminal devices such as mobile phones. After the terminal devices are assembled, they need to be numbered and the written numbers need to be checked. The contactless number writing method provided in the embodiment of the present application is applied to the terminal device. Based on the contactless number writing method provided in the embodiment of the present application, the terminal device can be numbered in a contactless manner. Here, the terminal device can be such as a computer, a smart phone, a tablet computer, a laptop computer, a PDA, a personal digital assistant (PDA), a navigation device, etc., and the embodiment of the present application does not specifically limit this.

[0067] It should also be noted that Near Field Communication (NFC) is a short-range high-frequency wireless communication technology developed on the basis of contactless radio frequency identification technology combined with wireless interconnection technology. The embodiment of the present application utilizes NFC technology to achieve contactless number writing.

[0068] It should also be noted that, in the embodiment of the present application, the terminal device supports the NFC function, so that the terminal device can directly establish a connection with the NFC card through NFC communication, and the NFC card carries the device information of the terminal device, so that the terminal device can directly read the device information of the terminal device based on the NFC communication connection between the two, thereby completing the number writing.

[0069] Here, the device information of the terminal device is the information such as the number of the terminal device that needs to be written in. It is equivalent to the identity mark of the terminal device, and the terminal device can be traced through the number.

[0070] In some embodiments, the device information may include at least: an identification number of the terminal device and a product serial code of the terminal device.

[0071] It should be noted that in the embodiment of the present application, the identity identification number of the terminal device may include the identity identification numbers of each module inside the terminal device, such as the communication module, battery module, display screen module, etc. inside the terminal device; through the identity identification number of each module, each module can be traced. For example, through the identity identification number of the display screen module, it is possible to determine which manufacturer the screen comes from, the production time, batch information, etc.

[0072] It should also be noted that the product serial number (SN code) of the terminal device is sometimes referred to as the product serial number (SerialNo). Here, the product serial number is a concept introduced to verify the "legal identity of the product". It is used to protect the user's genuine rights and interests and enjoy legal services. A set of genuine products only corresponds to one set of product serial numbers. The SN code can also be called: machine code, authentication code, registration application code, etc.

[0073] It should also be noted that when the terminal device is a mobile phone, the label information of the terminal device may also include: International Mobile Equipment Identity (IMEI), which is commonly known as the mobile phone serial number or mobile phone "serial number", which is used to identify each independent mobile phone and other mobile communication devices in the mobile phone network, which is equivalent to the ID card of the mobile phone.

[0074] S102: Read device information carried by the NFC card based on NFC communication.

[0075] It should be noted that after the terminal device and the NFC card establish a connection through NFC communication, the terminal device can read the device information carried by the NFC card based on the NFC communication between the terminal device and the NFC card.

[0076] In some embodiments, before reading the device information carried by the NFC card based on NFC communication, the method may further include:

[0077] Determine whether the target sector information of the NFC card is successfully identified; wherein the target sector information includes the target sector and the encrypted data in the target sector.

[0078] It should be noted that in an embodiment of the present application, the device information can be written into the target sector of the NFC card in advance, and when the device information is written into the target sector of the NFC card, the device information can also be encrypted based on a preset encryption algorithm, so that the NFC card carries the encrypted data obtained after the device information is encrypted.

[0079] When the terminal device reads the information in the NFC card, it only reads the target sector information corresponding to the target sector, thereby avoiding reading errors. It can be set during the development of the terminal device, so that the terminal device only reads the specified sector when reading the NFC card information.

[0080] In some embodiments, the method may further include:

[0081] If the target sector information of the NFC card is successfully identified, the step of reading the device information carried by the NFC card based on NFC communication is performed;

[0082] If the target sector information of the NFC card cannot be successfully identified, the step of establishing a connection with the NFC card through NFC communication is performed.

[0083] It should be noted that if the terminal device can successfully identify the target sector information of the NFC card, it will continue to read the device information carried by the NFC card based on NFC communication; however, in some cases, such as due to inappropriate placement of the NFC card or connection errors, the terminal device fails to successfully identify the target sector information of the NFC card, and then returns to the step of establishing a connection with the NFC card through NFC communication; in some cases, it may be because the chip of the NFC card is damaged, or the target sector of the NFC card does not match the target sector that can be read by the terminal that currently needs to write the number, etc., resulting in the terminal device failing to successfully identify the target sector information of the NFC card. At this time, it is necessary to replace the NFC card or re-execute the contactless writing method through other reasonable methods.

[0084] In some embodiments, reading the device information carried by the NFC card based on NFC communication may include:

[0085] Based on the NFC communication, the encrypted data in the target sector is decrypted using a preset decryption algorithm to obtain the device information carried by the NFC card.

[0086] It should be noted that the device information carried by the NFC card may be encrypted and converted into encrypted data. At this time, the terminal device needs to decrypt the encrypted data in the target sector of the NFC card based on NFC communication and use a preset decryption algorithm to obtain the device information carried by the NFC card.

[0087] It should also be noted that the preset decryption algorithm used by the terminal device when decrypting encrypted data may correspond to the encryption algorithm used when writing device information to the NFC card, thereby enabling direct and rapid decryption success.

[0088] S103: When the device information is read successfully, the device information is stored in a preset cache area of ​​the terminal device.

[0089] It should be noted that when the terminal device successfully obtains the device information carried in the NFC card, the read device information can be stored in a preset cache area of ​​the terminal device, that is, stored locally in the terminal device, thereby completing the writing of the terminal device.

[0090] It should also be noted that in some cases, the terminal device may fail to successfully read the device information or fail to successfully save the device information due to power outages (for example, the terminal device has just read the device information but has not yet completed saving it). At this time, it returns to the step of establishing a connection with the NFC card through NFC communication and re-executes the method of writing the number to the terminal device.

[0091] In some embodiments, after storing the device information in a preset cache area of ​​the terminal device, the method may further include:

[0092] The device information is displayed on a preset display device.

[0093] It should be noted that after the terminal device stores the device information in the preset cache area, the device information can also be displayed on the preset display device to confirm that the number writing is successful. That is, only when the number writing is successful, the preset display device will display the device information; on the one hand, it can confirm whether the number writing is successful; on the other hand, it can also verify whether the number writing is correct.

[0094] Here, the preset display device may be a display device such as a display screen of the terminal device itself; or a preset display device connected to the terminal device, such as an ink screen or any other device that can be connected to the terminal device to display the label information. The terminal device may print the device information on the preset display device based on the connection between the terminal device and the preset display device. In addition, the device information displayed on the preset display device may be all the device information stored in the terminal device, or only a part of it.

[0095] This embodiment provides a contactless number writing method, which is applied to a terminal device, and establishes a connection with an NFC card through NFC communication, wherein the NFC card carries the device information of the terminal device; the device information carried by the NFC card is read based on the NFC communication; when the device information is read successfully, the device information is stored in a preset cache area of ​​the terminal device. In this way, when writing a number to the terminal device, the terminal device only needs to establish a connection with the NFC card through NFC communication, and the device information carried by the NFC card can be saved locally in the terminal device to complete the number writing to the terminal device. The number writing process does not require the terminal device to have a hardware interface corresponding to the number writing fixture, and does not rely on the network environment, so that the contactless number writing function can be realized, and there is no requirement for the network environment, which reduces the dependence on the network environment and is convenient and fast.

[0096] In another embodiment of the present application, see Figure 2 , which shows a schematic flow chart of another contactless number writing method provided by an embodiment of the present application, which is applied to NFC cards. Figure 2As shown, the method may include:

[0097] S201. Obtain device information of a terminal device.

[0098] S202: Use a preset device to write device information into a target sector of the NFC card.

[0099] It should be noted that in the embodiment of the present application, after obtaining the device information of the terminal device, the obtained device information can be written into the target sector of the NFC card using a preset device. Here, the target sector of the NFC card means that when the terminal device reads the information in the NFC card, it only reads the data in the target sector, thereby avoiding reading errors. It can be set during the development of the terminal device, so that when the terminal device reads the NFC card information later, it only reads the target sector. The preset device is a device, apparatus, etc. that can write device information, etc. into the NFC card.

[0100] It should also be noted that in the embodiment of the present application, combined with the positioning requirements of the product, if the NFC card needs to be shipped with the corresponding terminal device, then each terminal device can be equipped with an NFC card, that is, only the device information of the corresponding terminal device is written into this NFC card.

[0101] If the NFC card does not need to be shipped with the terminal device, then after completing the number writing for one terminal device, the device information written in the NFC card can be cleared, and then the device information of the next terminal device can be written, so that the NFC card can be used to write the number for the next terminal device.

[0102] In addition, since an NFC card can have multiple sectors, the embodiments of the present application can also enable the sectors in which the NFC card can write data to correspond to different terminal devices respectively. In this way, the tag information of multiple terminal devices can be written in different sectors on an NFC card. Moreover, since each terminal device will only read the tag information of its corresponding designated sector, there will be no reading confusion, thereby realizing the use of one NFC card to write numbers to multiple terminal devices.

[0103] In some embodiments, writing device information into a target sector of an NFC card using a preset device may include:

[0104] Encrypt device information using a preset encryption algorithm to generate encrypted data;

[0105] The encrypted data is written into the target sector of the NFC card using a preset device.

[0106] It should be noted that when the present application is implemented to write device information into the target sector of the NFC card, in order to ensure security, the device information can also be encrypted using a preset encryption algorithm to generate encrypted data, and then the encrypted data can be written into the target sector of the NFC card using a preset device.

[0107] In some embodiments, the preset device may include an NFC card reader, and the preset encryption algorithm may include an AES algorithm.

[0108] It should also be noted that an NFC card reader is a device that can write data to an NFC card. The device information can be encrypted using the Advanced Encryption Standard (AES) method, or the tag information can be encrypted using other feasible methods, such as various asymmetric encryption algorithms or symmetric encryption algorithms. This is not specifically limited in the embodiments of the present application.

[0109] In some embodiments, the device information may include at least: an identification number of the terminal device and a product serial code of the terminal device.

[0110] S203: Establish a connection with the terminal device through NFC communication, so that the terminal device can write device information contactlessly based on NFC communication.

[0111] It should be noted that in the embodiment of the present application, after the device information of the terminal device is written into the target sector of the NFC card, the NFC card can establish a connection with the terminal device through NFC communication, so that the corresponding device information can be directly obtained from the NFC card based on NFC communication, thereby realizing contactless number writing. Since NFC is a near-field communication technology, at this time, the NFC card needs to be brought close to the terminal device (such as within 10 cm of the distance between the two), and the NFC card needs to be placed in the NFC receiving area of ​​the terminal device so that the terminal device can recognize the NFC card to complete the number writing.

[0112] This embodiment provides a contactless number writing method, which is applied to an NFC card, by obtaining the device information of a terminal device; using a preset device to write the device information into a target sector of an NFC card; and establishing a connection with the terminal device through NFC communication, so that the terminal device can write the device information contactlessly based on NFC communication. In this way, since the device information of the terminal device is written into the target sector of the NFC card, after the NFC card and the terminal device establish a connection through NFC communication, the terminal device can directly obtain the device information from the NFC card to complete the number writing. Thus, contactless number writing is achieved, and there is no requirement for the network environment.

[0113] In another embodiment of the present application, see Figure 3, which shows a detailed flow chart of a contactless number writing method provided by an embodiment of the present application. Figure 3 As shown, the detailed process may include:

[0114] S301, using an NFC card reader to write encrypted terminal device ID, SN code and other information into the target sector of the NFC card.

[0115] It should be noted that the embodiment of the present application first uses an NFC card reader to write the encrypted terminal device's identity document (ID), SN code and other information into the specified sector of the NFC card. Here, the ID of the terminal device is the identity document of the device terminal in the aforementioned embodiment, which can also be called the unique identification ID of the device end, and the SN code is the product serial code in the aforementioned embodiment, also called the SN number.

[0116] Since the target sector of the NFC card can be a corresponding sector that can be recognized by a pre-specified terminal device, it can also be called a designated sector. In addition, in the embodiment of the present application, the NFC card is also called an NFC card end, and the terminal device is also called a device end.

[0117] S302: Place the NFC card in the NFC receiving area of ​​the terminal device.

[0118] S303: Determine whether the terminal device can recognize the data of the target sector of the NFC card.

[0119] It should be noted that after placing the NFC card in the NFC receiving area of ​​the terminal device, it is determined whether the terminal device can recognize the data of the target sector of the NFC card. At this time, the terminal device may fail to recognize the data of the target sector of the NFC card due to reasons such as the NFC card being placed in an inappropriate position, being placed too far away, or the chip of the NFC card being damaged or causing errors.

[0120] If the judgment result is yes, execute step S304, otherwise execute step S302.

[0121] It should also be noted that if it is determined that the failure to successfully identify is due to damage to the NFC card, the NFC card can be replaced, the encrypted terminal device ID, SN and other information can be rewritten, and identification can be performed again.

[0122] S304: The terminal device reads the specified data of the NFC card and decrypts it.

[0123] It should be noted that the designated data is the encrypted data in the target sector of the NFC card, that is, the encrypted device ID, SN code and other information, which is read and decrypted by the terminal device.

[0124] S305: Whether the terminal device successfully reads the data and stores it in the flash.

[0125] It should be noted that after the terminal device reads the data of the target sector of the NFC card and decrypts it, it needs to further determine whether the terminal device has successfully read the data and stored it in the flash. At this time, the terminal device may fail to successfully read the data or fail to save the read data to the flash due to power failure, poor signal, etc.

[0126] If the judgment result is yes, execute step S306, otherwise execute step S302.

[0127] S306, printing the ID of the terminal device on the ink screen.

[0128] After the terminal device successfully reads the data and stores it in the flash, the terminal device ID is printed on the ink screen to confirm that the number writing is successful and to verify whether the number writing is correct.

[0129] The specific implementation of the aforementioned embodiment is elaborated in detail through the above-mentioned embodiment, from which it can be seen that the contactless number writing method proposed in this embodiment, on the one hand, when writing the number to the terminal device, it is only necessary to place the NFC card with the device information of the terminal device written close to the NFC receiving area of ​​the terminal device to realize the number writing process and realize contactless number writing; on the other hand, because the device information of the terminal device is written into the specified sector of the NFC card, and the terminal device will only read the data of the specified sector of the NFC card, errors caused by confusion in reading and writing are avoided; on the other hand, when the device information of the terminal device is written into the NFC card, the device information is also encrypted, and the terminal device decrypts it accordingly when reading, which also improves the security of the number writing process; finally, the device information read by the terminal device is displayed on the ink screen, thereby ensuring the success of number writing and verifying whether the device information is correct.

[0130] In short, the embodiment of the present application provides a method for contactless number writing for a terminal device supporting NFC function through NFC card recognition technology. The unique identification ID, SN number and other related data information of the terminal device (such as a mobile device) are written to the target sector of the NFC card through the NFC card reader, and then the NFC card is brought close to the terminal device. The terminal device will recognize the data of the target sector of the NFC card, write the data recognized from the NFC card into the flash, and display the relevant device ID of the terminal device on the ink screen.

[0131] The contactless number writing method provided in the embodiment of the present application uses an NFC card to perform a contactless number writing function for a terminal device. On the one hand, it does not require contact with the hardware interface of the terminal device, such as a pin, a serial port, etc., and the number writing function of the terminal device is realized through the relevant information of the NFC card sector, which is convenient and fast; on the other hand, the contactless number writing function can be realized without relying on the network environment. It only needs to place the NFC card in the NFC receiving area of ​​the terminal device, and the terminal device can automatically realize the number writing function, which is fast and convenient.

[0132] Compared with the number writing scheme of the related art, the number writing scheme provided by the embodiment of the present application has at least the following advantages: Different from the traditional number writing jig that needs to use the hardware interface of the terminal device, such as serial port, pin, etc. to connect and communicate with the terminal device to complete the number writing operation, the embodiment of the present application uses NFC card for information transmission, writes the ID, SN and other information of the terminal device on the NFC card end, and only needs to put the NFC card close to the NFC receiving area of ​​the terminal device to realize the number writing process, completing the contactless number writing function. Different from some devices that use network servers to write numbers, the embodiment of the present application uses NFC cards for number writing operations, which also realizes the contactless number writing function, and does not rely on the network environment, is minimally affected by the environment, and is convenient and fast.

[0133] In summary, the embodiment of the present application is a method for contactless number writing on a device supporting NFC function based on an NFC card. First, an NFC card reader is used to write the ID, SN and other device information of the terminal device to the target sector of the NFC card using AES encryption, and then the NFC card is placed close to the NFC reading position of the terminal device. The terminal device can automatically read the sector information of the NFC card, decrypt the encrypted data, and store the read terminal device ID, SN and other data information to the flash of the device. The number writing function of the terminal device is completed. After the number is successfully written, the ink screen of the terminal device will display the entered terminal device ID number. Therefore, there is no need for the terminal device to provide relevant hardware interfaces, and there is no need to use a number writing fixture. Only the NFC card can be used through the NFC function to write relevant data for the terminal device contactlessly. Moreover, it does not rely on the network environment. It only needs to write relevant device information for the NFC card through the NFC reader, and then place the NFC card at the NFC reading position of the terminal device. The terminal device can read the NFC card information and automatically complete the number writing process. The embodiment of the present application does not require the terminal device to set aside a special hardware interface for number writing operations, nor does it need to use the network environment to write numbers, which greatly simplifies the number writing process and reduces costs.
