First of all, regarding the QR-code. I haven't seen it on any packaging in the Nordic Country's the past years?
It used to be on some media big posters but it never "hit the market" to say. It was a bit popular in middle of 2000.
Is it a big thing in SK and Thailand maybe? Haven't seen it much here, but if it helps with marketing and people use it, of course we should have it :)
