I found many libraries / posts in B4A forum for QR code creation & scanning. I'm confused which one to use / which one is latest and simplest to use with basic features.
If anypne has gone through this excersice recently, it will save me some time.
The one I use is B4aZxing (V1.5). Extremly happy with results. I only would like to put a customized message in the scan screen, but I can live without it.
This project will allow you to put a customized message in the scan window. It also allows you to change the size of the scan window. See the next post (#4) for a link to an explanation about how to change the color of the laser, viewfinder, mask, possible result point, result points, frame, etc
