[0067] In this embodiment, the electronic business card component 100 includes a communication unit 102, a display unit 104, and a controller unit 106. The communication unit 102 communicates with a server storing business card information, and the display unit 104 communicates with the communication unit 102 to display the business card information obtained by the communication unit 102 according to a specified mode. The controller unit 106 controls the working state of the communication unit 102 and the display unit 104, thereby improving the portability, ease of use, and information security of the electronic business card.

[0068] The following is a detailed description of the structure of the electronic business card component 100.

[0069] In one exemplary embodiment of this disclosure, such as Figure 2As shown, the controller unit 106 is equipped with an ESP32-C3 Mini development board 202. The ESP32-C3 Mini development board 202 includes a wireless communication control module 2022, an I2C communication module 2024, GPIO pins 2026, and a low-power management module 2028. The wireless communication control module 2022 can control the communication unit 102 to communicate with the server storing the business card information. The I2C communication module 2024 communicates with the display unit 104 based on the I2C communication protocol. The GPIO pins 2026 are provided with multiple general-purpose pins. The low-power management module 2028 is used to control the display unit 104 to display according to the specified mode.

[0070] In one exemplary embodiment of this disclosure, such as Figure 3 As shown, the wireless communication control module 2022 is a Wi-Fi communication control module 20222. The Wi-Fi communication control module 20222 can control the communication unit 102 to access the Wi-Fi network based on the 802.11b / g / n protocol and communicate with the server storing the business card information.

[0071] In one exemplary embodiment of this disclosure, such as Figure 4 As shown, the communication unit 102 is equipped with a Wi-Fi scanning module 302. The Wi-Fi scanning module 302 scans Wi-Fi networks within a specified distance to determine open Wi-Fi networks within the specified distance, and accesses the corresponding open Wi-Fi network according to the signal strength of at least one open Wi-Fi network determined by the scan.

[0072] In the above embodiments, by scanning open Wi-Fi networks and accessing them based on signal strength, the electronic business card component can be automatically connected to the network. By using signal strength as a factor to determine the access order, the communication quality of the accessed open Wi-Fi network can be improved, thereby helping to improve the reliability and timeliness of updating and maintaining business card information.

[0073] In one exemplary embodiment of this disclosure, such as Figure 5 As shown, the display unit 104 is provided with a display module 402 and an I2C interface 404. The display module 402 is used to display the business card information. The I2C interface 404 is connected to the controller unit 106. The display module 402 receives the business card information obtained by the communication unit 102 based on the I2C interface 404, and displays the business card information according to the specified mode sent by the controller unit 106 received by the I2C interface 404.

[0074] In one exemplary embodiment of this disclosure, such as Figure 6 As shown, the electronic business card component 100 also includes:

[0075] The power supply unit 108 is provided with a power supply and / or a power access module. The power supply unit 108 is connected to the display unit 104, the communication unit 102 and the controller unit 106 for power supply. The power supply includes a storage battery and / or a solar energy conversion device. The power access module is used to connect to industrial frequency AC power or external DC power.

[0076] In the above embodiments, by setting multiple power supply methods, the electronic business card component can operate more flexibly, diversely, and for longer periods while powered on, reducing the time cost of manual maintenance of electronic business cards. The battery can be a lead-acid battery, a lithium battery, or a button battery, but is not limited to these.

[0077] In one exemplary embodiment of this disclosure, such as Figure 7 As shown, the electronic business card component 100 also includes:

[0078] A low-power management unit 110 is connected to the power supply unit 108 and is configured to control the power supply unit 108 to supply power in a low-power mode.

[0079] In the above embodiments, after the communication unit is connected to the network or disconnected from the network for an extended period, the low-power management unit can adjust its operating power according to the network status. When it detects that the communication unit cannot connect to the Wi-Fi network for an extended period, the low-power management unit can automatically switch the system to a deeper sleep mode to further reduce power consumption. Conversely, when the communication unit successfully connects to the network, the low-power management unit can appropriately increase the system's operating power to ensure the timeliness of business card information data updates and data interaction.

[0080] In one exemplary embodiment of this disclosure, such as Figure 8 As shown, the electronic business card component 100 also includes:

[0081] A touch button 112 is connected to the controller unit 106. The touch button 112 responds to an external touch signal to trigger the controller unit 106 to determine that the business card information is displayed in a specified mode.

[0082] In the above embodiments, users can adjust the display mode of the electronic business card component by touch buttons, for example, switching from normal display mode to encrypted display mode, or from encrypted display mode to normal display mode. Normal display mode displays all information, while encrypted display mode masks or does not display key information.

[0083] In the above embodiments, the touch button can also be used for exchanging business card information within the near-field communication range. A function similar to AirDrop can be integrated into the communication module, allowing users to exchange electronic business cards with other electronic business card components via near-field communication technology (Bluetooth) without displaying the business card content. This method not only improves user privacy and security but also enhances user interactivity. Specifically, upon detecting that a user has pressed the button to trigger the electronic business card exchange mode, the system automatically searches for other electronic business card components within a specified distance or belonging to the same open Wi-Fi network, and exchanges the electronic business cards after user confirmation.

[0084] Figure 9 This is a flowchart of a method for displaying business card information according to an exemplary embodiment of this disclosure.

[0108] In one exemplary embodiment of this disclosure, such as Figure 11 , Figure 12 and Figure 13 As shown, the display unit is responsible for showing the user the privacy number and consists of the following parts:

[0109] 1. 2.4-inch OLED LCD screen: A small, low-power display that can clearly show relevant information.

[0110] 2. I2C interface 404: Connects to controller unit 106 to receive and display privacy number.

[0121] In one exemplary embodiment of this disclosure, such as Figure 14 As shown in step 1400 of the electronic business card component's business card information maintenance process, a business card maintenance app and a corresponding WeChat official account have been developed to support the electronic business card component. Users can modify their company, job title, real phone number, and linked privacy account information through the app or official account. The platform modifies the information submitted by the user and retains a record of the changes for the user to review.

[0122] In the above embodiments, we thank you for your valuable suggestions on the Mini Privacy Number Business Card System. Regarding your suggestions on supporting the display of multiple business cards and how to implement this function based on the existing design, I have conducted in-depth consideration and research. Given that you mentioned the original design can basically achieve the required functions, only the gesture logic for switching business cards needs to be added, and multiple numbers need to be bound to one business card in the app and official account backend. The specific implementation plan is reported as follows:

[0123] (1) Business card switching gesture logic:

[0124] Based on the existing external buttons, long press and double tap gestures will be introduced as triggers for switching business cards. For example, users can enter the business card switching mode by long pressing the button for more than 3 seconds, and then cycle through different business cards by short pressing the button.

[0125] The display screen will show the serial number or name of the current business card to help users identify which business card is currently displayed.

[0126] (2) Support for APP and WeChat Official Account backends:

[0127] Add a feature to the app and official account backend that allows users to bind multiple privacy numbers to a single business card. Users can set multiple different privacy numbers for each business card in the backend, with each number corresponding to a different scenario or purpose.

[0128] Users can select the currently displayed business card and its corresponding privacy number through the system backend. Each time a business card is switched, the electronic business card component will retrieve the latest business card information and privacy number from the backend and update the display accordingly.

[0129] (3) Backend logic adjustment:

[0130] The backend system maintains a private number list for each user's business card. Users can manage these numbers through the app or official account backend, including adding, deleting, or modifying them.

[0131] When a user switches business cards using the electronic business card component, the component will send a request to the backend to obtain the latest privacy number information of the currently selected business card and update the display accordingly.

[0132] In one exemplary embodiment of this disclosure, such as Figure 15 As shown, the workflow of the electronic business card component includes:

[0133] Step S1502: After the system is powered on, the microcontroller module starts up and performs a Wi-Fi scan: the microcontroller module scans the surrounding Wi-Fi networks.

[0134] Step S1504, Filter open networks: Select open networks from the scan results.

[0135] Step S1506, Waiting for manual wake-up: The device enters low power mode and waits for the user to manually wake it up. The user can manually wake up the device by pressing an external button.

[0136] Step S1508, Wi-Fi connection: The microcontroller module connects to the open network with the strongest signal.

[0137] Step S1510, Obtain Privacy Number: Once the connection is successful, the microcontroller module sends an HTTP request to the server to obtain the latest privacy number. After obtaining the privacy number, the microcontroller module sends data to the display module via the I2C interface to update the privacy number displayed on the screen.

[0138] Step S1512, Low power mode: When there is no operation, the system enters deep sleep mode to save energy.

[0139] In one exemplary embodiment of this disclosure, such as Figure 16 As shown, the architecture 1600 to which the electronic business card component belongs includes: a communication cloud privacy number platform gateway server cluster, a communication cloud privacy number platform OpenApi server cluster, a communication cloud privacy number platform business card server cluster, a database persistent storage device, an in-memory database device, a user information maintenance platform, and a mini electronic business card terminal.

[0140] The core innovation of this disclosure lies in the design of a novel miniature electronic business card component, which can instantly update the displayed privacy number and other information after the user triggers a button, and provides a privacy protection mechanism through a miniature LCD screen.

[0141] The key technological innovations that this disclosure aims to protect include:

[0142] Information such as privacy numbers can be displayed in a timely manner, and data exchange can be achieved using the Wi-Fi module and HTTP request function of the ESP32-C3 Mini development board;

[0143] The 11-digit privacy number is displayed using a miniature LCD screen, providing a privacy protection mechanism to prevent users' real phone numbers from being leaked;

[0144] Low-power design, extending battery life through deep sleep mode and external button wake-up mechanism;

[0145] In addition, solar panel-assisted power supply solutions enhance the product's sustainability and environmental friendliness.

[0146] These technological innovations collectively constitute the unique value of this disclosure—providing a secure and convenient business card solution that achieves the dual goals of privacy protection and information management.

[0147] Corresponding to the above method embodiments, this disclosure also provides a business card information display device, which can be used to execute the above method embodiments.
