It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0036] Near Field Communication (NFC) is a short-range, high-frequency wireless communication technology that allows devices to exchange data within a contactless range. NFC technology boasts advantages such as portability, high security, and strong anti-interference capabilities. Leveraging these advantages, NFC technology has been widely applied in various fields including mobile payment, identity authentication, transportation, access control, and security.

[0037] In related technologies, if a near-field communication device 100 is accidentally lost, it is difficult to find it after it is lost, which will cause inconvenience to the user's life and cause unnecessary trouble.

[0038] In this application embodiment, the near-field communication device 100 includes, but is not limited to, smart bracelets, smartwatches, access cards, public transport cards, etc.

[0039] To improve the problem of near-field communication device 100 being difficult to recover after being lost, please refer to the following: Figure 1 This application provides a near-field communication device anti-loss system, which includes a near-field communication device 100, a mobile terminal 200, a loss reporting terminal 300, and a server 400.

[0040] The near-field communication device 100 internally includes an interaction module 20, which is the core module used by the near-field communication device 100 to realize information transmission and feedback between the user and the mobile terminal 200 or other devices. In this embodiment, the interaction module 20 includes a main control chip 21 and a communication antenna 22, which are electrically connected. The main control chip 21 stores the identification information of the near-field communication device 100, which is unique. The communication antenna 22 is used to broadcast a handshake signal containing the identification information to the external mobile terminal 200. In this embodiment, the handshake signal refers to a series of control signals or messages exchanged between the two communicating parties (i.e., the near-field communication device 100 and the mobile terminal 200) before establishing a formal connection or starting data transmission, for negotiating parameters, synchronizing states, confirming the existence of the other party, establishing trust, and ensuring that both parties are ready.

[0041] Mobile terminal 200 communicates with server 400. In some embodiments, mobile terminal 200 and server 400 communicate via Wi-Fi, and signal and data transmission are achieved through Wi-Fi connection. In some embodiments, mobile terminal 200 receives handshake signals sent by near-field communication device 100 via Bluetooth. After receiving the handshake signal, mobile terminal 200 can upload the identification information carried in the received handshake signal and its own location information (i.e., geographical location, which can be provided by the GPS (Global Positioning System) module of mobile terminal 200) to server 400. Mobile terminal 200 includes, but is not limited to, devices such as mobile phones, tablets, or smartwatches.

[0042] The reporting terminal 300 is the terminal device of the user who lost the near-field communication device 100. In some embodiments, the reporting terminal 300 and the server 400 are connected via Wi-Fi, and signal and data transmission is achieved through the Wi-Fi connection. In some embodiments, the reporting terminal 300 and the near-field communication device 100 were already bound before the device was lost. The reporting terminal 300 can be a mobile phone, tablet, or smartwatch, etc.

[0043] After receiving the identification information and location information, the server 400 can match the corresponding reporting terminal 300 (i.e., the terminal device that has been bound to the near-field communication device 100) according to the identification information, and feed back the location information to the corresponding reporting terminal 300. Specifically, the feedback can be sent to the reporting terminal 300 through APP reminders, pop-up notifications, or SMS notifications. The server 400 in this application utilizes cloud technology, i.e., a cloud server 400.

[0044] The near-field communication (NFC) device anti-loss system of this application involves the NFC device 100 actively broadcasting a handshake signal containing unique identification information. When a mobile terminal 200 enters the broadcast range, it can recognize the presence of the NFC device 100 and receive the handshake signal. Subsequently, the mobile terminal 200 can upload the identification information and its own location information to the server 400, and then communicate with the reporting terminal 300 through the server 400 to feed back the location information to the reporting terminal 300. This system effectively improves the problem of the NFC device 100 being difficult to find after loss, provides a technical means for quickly locating the lost NFC device 100, and significantly improves the success rate of finding the lost NFC device 100.

[0045] In some implementations, the reporting terminal 300 is communicatively connected to the server 400 and can send control commands to the server 400. Upon receiving a control command, the server 400 can store it. Once a mobile terminal 200 with the same operating system as the near-field communication device 100 establishes a communication connection with the near-field communication device 100 based on a handshake signal, the server 400 can forward the stored control commands to the mobile terminal 200. Subsequently, the mobile terminal 200 sends the control commands to the main control chip 21 of the near-field communication device 100. Upon receiving the control commands, the main control chip 21 can control the corresponding components to perform actions.

[0046] In some implementations, the main control chip 21 and the mobile terminal 200 run the same operating system. On the one hand, this reduces development difficulty and costs; on the other hand, it reduces compatibility issues and facilitates subsequent version updates, thereby improving convenience.

[0047] It should be noted that this application does not specifically limit the type of operating system, and those skilled in the art can choose flexibly according to the actual product situation. For example, both the main control chip 21 and the mobile terminal 200 run the Android operating system; or, both the main control chip 21 and the mobile terminal 200 run the iOS operating system; or, both the main control chip 21 and the mobile terminal 200 run the HarmonyOS operating system.

[0048] Please continue reading. Figure 1 The working process of the near-field communication device anti-loss system of this application is described.

[0049] Specifically, after the near-field communication device 100 is lost, it can actively broadcast a handshake signal carrying identification information. If a mobile terminal 200 running the same operating system as the lost near-field communication device 100 is nearby, the mobile terminal 200 can receive the handshake signal sent by the near-field communication device 100. After receiving the handshake signal, the mobile terminal 200 can upload the identification information carried in the received handshake signal and its own location information to the server 400. Subsequently, the server 400 matches the corresponding reporting terminal 300 based on the identification information and sends the location information back to the corresponding reporting terminal 300. The user who lost the near-field communication device 100 can retrieve the near-field communication device 100 by viewing the location information on the reporting terminal 300.

[0050] Furthermore, after a user discovers the near-field communication device 100 is missing, the user can operate the reporting terminal 300 to send control commands (including but not limited to commands to activate alarm notifications) to the server 400. Upon receiving the control commands from the reporting terminal 300, the server 400 can store them. When a mobile terminal 200 with the same operating system as the lost near-field communication device 100 approaches it, the mobile terminal 200 can receive a handshake signal and establish a communication connection with the near-field communication device 100 based on the handshake signal. Subsequently, the server 400 can forward the stored control commands to the mobile terminal 200, which then sends the control commands to the main control chip 21 of the near-field communication device 100. Upon receiving the control commands, the main control chip 21 can control the corresponding components to perform actions according to the commands.

[0051] Among them, the reporting terminal 300 and the mobile terminal 200 can be the same terminal device.

[0052] In the embodiments of this application, please refer to the following: Figure 1 The near-field communication device 100 of this application includes a housing 10 and an interaction module 20.

[0053] Housing 10 is the outer shell of near-field communication device 100, providing installation space for internal components and protecting them. Housing 10 is typically made of PVC (polyvinyl chloride) plastic, which has good stability, corrosion resistance, and lightweight.

[0054] The interaction module 20, located within the housing 10, is the core module of the near-field communication device 100 used to enable information transmission and feedback between the user and the mobile terminal 200 or other devices. In this embodiment, the interaction module 20 includes a main control chip 21 and a communication antenna 22, which are electrically connected. The main control chip 21 stores the identification information of the near-field communication device 100, which is unique and includes, but is not limited to, the MAC address (Bluetooth address) of the near-field communication device 100. The communication antenna 22 is used to broadcast a handshake signal containing the identification information to the external mobile terminal 200.

[0055] This application provides an interaction module 20 within the housing 10 of a near-field communication (NFC) device 100. This interaction module 20 actively broadcasts a handshake signal containing unique identification information to the outside world, enabling a mobile terminal 200 to receive the handshake signal and, upon receiving it, upload its identification information and location information to a server 400. By incorporating the interaction module 20 within the NFC device 100, hardware support is provided for locating a lost NFC device 100, thereby helping to improve the difficulty of recovering a lost NFC device 100.

[0056] In some implementations, the main control chip 21 is a Bluetooth Low Energy (BLE) SOC (System on Chip) chip. A BLE SOC chip is a highly integrated chip with a built-in Bluetooth wireless communication module. It integrates a processor, communication radio frequency, memory, and peripheral interfaces, and is the core component for the near-field communication device 100 to achieve wireless communication and device control. This allows the near-field communication device 100 to complete data transmission, reception, processing, and control functions on a single chip, greatly improving the system's integration and reliability. Furthermore, the BLE SOC chip has advantages such as low power consumption, high integration, and small size. It can be housed inside the casing 10 without affecting the original appearance of the near-field communication device 100, which is beneficial for the compact design of the near-field communication device 100. It also allows the device to operate for extended periods without frequent charging, making it more convenient to use. It should be noted that this application does not specifically limit the type of the main control chip 21; those skilled in the art can flexibly adjust the type of the main control chip 21 according to actual product requirements.

[0057] In some implementations, see Figure 1The interaction module 20 also includes a timer 23, which is electrically connected to the main control chip 21. The timer 23 provides a basic and stable clock signal for the operation of the main control chip 21, helping to maintain system stability and ensure the accuracy of signal transmission. The main control chip 21 can control the communication antenna 22 to periodically broadcast handshake signals based on the timing signal provided by the timer 23. This saves energy. The timer 23 includes, but is not limited to, a crystal oscillator.

[0058] In some implementations, see Figure 1 The interaction module 20 also includes a battery 24, which is electrically connected to the main control chip 21. The battery 24 supplies power to the main control chip 21, providing essential power for its operation and ensuring its stable operation. This application does not specify the type of battery 24; those skilled in the art can flexibly adjust the type of battery 24 according to actual product requirements. For example, the battery 24 can be a button cell battery, etc.

[0059] In some implementations, see Figure 1 The interaction module 20 also includes an alarm 25, which is electrically connected to the main control chip 21 and is used to issue an alarm notification under the control of the main control chip 21. With this configuration, firstly, if the near-field communication device 100 is lost in a relatively hidden corner, issuing an alarm notification can help the lost user quickly locate and retrieve the near-field communication device 100; secondly, issuing an alarm notification can attract attention from the surrounding area, and when someone approaches the near-field communication device 100, if there is a mobile terminal 200 with the same operating system as the main control chip 21 nearby, the near-field communication device anti-loss system in this application can provide the lost user with the location information of the near-field communication device 100, facilitating its retrieval; thirdly, issuing an alarm notification can also deter unauthorized possessors to a certain extent.

[0060] Understandably, after discovering the loss of the near-field communication device 100, the user can operate the reporting terminal 300 to send a control command to the server 400 to activate the alarm notification. Upon receiving the control command, the server 400 can store it. When a mobile terminal 200 with the same operating system as the lost near-field communication device 100 approaches it, the mobile terminal 200 can receive a handshake signal from the near-field communication device 100 and establish a communication connection based on the handshake signal. Subsequently, the server 400 can forward the stored control command to the mobile terminal 200. The mobile terminal 200 can then send the control command to the main control chip 21 of the near-field communication device 100. Upon receiving the control command, the main control chip 21 can control the alarm 25 to issue an alarm notification.

[0061] It should be noted that this application does not specifically limit the type of alarm 25, and those skilled in the art can flexibly adjust the type of alarm 25 according to the actual product situation. For example, alarm 25 can be a buzzer, which can emit a buzzing sound under the control of main control chip 21; or alarm 25 can also be an indicator light, which can emit a flashing light under the control of main control chip 21; or, a buzzer and an indicator light can be set at the same time, which can emit a buzzing sound and / or flashing light under the control of main control chip 21.

[0062] In some implementations, see Figure 1 The near-field communication device 100 also includes a near-field sensing module 30. The near-field sensing module 30 is a component that enables data transmission and interaction between devices through short-range high-frequency wireless signals. It is the core module for realizing the basic functions of the near-field communication device 100 (i.e., access control, identity recognition, etc.). The near-field sensing module 30 is located inside the housing 10 and is used to communicate with the external card reader 500 to realize the basic functions of the near-field communication device 100.

[0063] In some implementations, such as Figure 1 As shown, the near-field sensing module 30 also includes a sensing chip 31, an induction coil 32, and an AC / DC converter 33. The sensing chip 31 is used to store data. The induction coil 32 is disposed around the outer periphery of the sensing chip 31 and is electrically connected to it. The induction coil 32 can establish a communication connection with the card reader 500 and, during the establishment of the communication connection, cuts the magnetic field lines of the card reader 500 to generate alternating current. The AC / DC converter 33 is electrically connected to the sensing chip 31 and the induction coil 32, and can convert the alternating current output by the induction coil 32 cutting the magnetic field lines of the card reader 500 into direct current to power the sensing chip 31, providing power support for the sensing chip 31.

[0064] Specifically, when the near-field communication device 100 enters the sensing range of the card reader 500, the induction coil 32 cuts the magnetic field lines generated by the card reader 500, generating alternating current. The AC / DC converter 33 converts the AC current into DC current and supplies power to the sensing chip 31. After receiving power, the sensing chip 31 can transmit its stored data to the card reader 500 via electromagnetic induction through the induction coil 32 to achieve data transmission, thereby realizing the basic function of the near-field communication device 100.
