I'm trying to print QR Code in a paper but it's now not readable by any application from mobile app. Also tried the latet e-invoicing oss note, pretty much worked but it's not decoding it properly. As we already know there is a MIME type or something while creating QR Code to identify text, URL, SMS etc.
Kindly let me know how to implement or show a QR Code to end user? What kind of encoding and decoding is required to achieve this?
