I was looking for QR code example. And I found the below link for creating QR code from a string. This solution is working fine but if I have a class lets say Student and have fields: id,name,phone. Then create an object of Student class and want to make QR code out of all the info of an object(Which should be information of 1 student).
How am I going to do it? And after making the QR code, how am I going to retrieve it back to the original object?
