Anyone actually use these things? Do you scan them with your phone/tablet if you see them?
Depends on if I'm interested in what they're on or not. I uses Google goggles and it does a great job recognizing these as well as text and even some images.
It's a good way to save stuff for looking up later.
All men dream, but not equally. Those who dream by night in the dusty recesses of their minds wake in the day to find that it was vanity; but the dreamers of the day are dangerous men, for they may act their dreams with open eyes, to make it possible. - Lawrence
I know what they are, but never use them.
Used it to load Gator's steel composition database once last year

We had a Christmas cookie recipe contest at the paper I work at. The winning recipe was sold at Central Market here with the proceeds going to a our goodfellows charity. In central market we had QR codes on all the signs and posters in the store that linked back to the winning recipe online.
