Embodiment 1
[0076] see figure 1 , figure 1 It is a schematic flowchart of a method for starting two-dimensional code display disclosed in an embodiment of the present invention. in, figure 1 The described method for starting two-dimensional code display can be applied to a display device and a background server, wherein the display device establishes a connection with the user terminal based on wireless Bluetooth, and the display device communicates with the background server through the user terminal. Further, the screen of the display device is an electronic paper display screen (also called electronic paper screen or digital paper screen), and the display device is used to dynamically display a two-dimensional code. like figure 1 As shown, the method for starting two-dimensional code display may include the following steps:
[0077] 101. The display device sends a target parameter to the background server, where the target parameter includes the cumulative update times of the displ...
