goldnugget i do note you stated " some areas......"
bored people at bus stops, tags on people entering seminars, events and conventions, i think qr is valid.
qr is a good use of "realestate" in a traditional media advert, it basically is the click/link button of a paper advert, i have a few clients that use it VERY well and get success.
saves typing "www.domainname.com.au/2013, for your pubs new years eve promo page.
blue wren: as you enter a pub in your town of 10 pubs and you can scan a qr that will in the future tell you when every happy hour is about to begin, what specials are on bundy rum, what bands are playing next week. it will take you to a webpage where you can signup for a free case of beer promo and then automatically download the App that is called "tamworth" because thats where the person lives ( or ulladulla it doesn't matter)
