But I have absolute no clue if it works, I can install it but it needs cordova and it's for the C2 Runtime only. It's converted with the Plugin Converter from BlackHornet.
This guy uploaded the QR plugin, install the .c3addon he uploaded and you just have to run it with c2 runtime. I have not made the example with HTML since it worked with the QR, just use c2 runtimes as i said, if u need help on how that works i can upload an example of the QR plugin on c3 but with c2 runtime.
