Hello everyone, I am a new user, just registered and I congratulate you on the forum.
I do not know if they are in the right section if it is in the wrong section, prey moderators to move my question.

I would ask if there is a similar or more complex method of QR-Code - http://en.wikipedia.org/wiki/QR_Code

Thanks and regards

This is a web programming/development forum, QR and barcodes don't really fall in to that scope.
