qr code decoder

Technology selectionIn order to solve the problem that the QR code cannot be scanned, the appropriate technical means must be chosen. Since our app refers to someone else's developed zbar-based image recognition plug-in, without the ability to modify the image recognition plug-in, I decided to solve this problem on the server side, considering the general type of the algorithm, in the service-side verificat
