NFC Screen Flooding Operation Process

Step 1: Bind the device (mandatory for first-time use)

Open the installed NTAG, enter the home page and click "Bind Device" to prepare for the device binding operation.

Step 2: Complete the binding

Bring your mobile phone close to the NFC center of the device, and the system will automatically scan and complete the binding.

After successful binding, the page will display device-related information (such as UID, colors: white (1), black (0), yellow (2), red (3), resolution: 240×416).

Step 3: Select the picture

After binding the device, click "Select lmage", which supports two ways to import pictures. After making your selection, click the check button in the upper right corner of the picture to confirm.

Step 4: Select the algorithm and prepare to refresh

By default, the "Dithering Algorithm" is used. You can switch to the "Color Grading" as needed. For screen preview, click "Refresh Screen".

Step 5: Complete the screen refresh

Bring your phone close to the NFC center of the device again. The system will display "Refreshing screen".

Once it prompts "Operation successful", the entire screen refreshing process is completed.
