I've never been convinced by QR codes in mainstream use, but when I
was at Kew we used them in a very specific way in our gardens mobile
app that addressed some of the points raised:
- the main call to action was through the app which had a reader built
in as a core feature, so the target user group didn't have the barrier
of wondering what to do, getting a reader app etc
- crucially, if the user scanned it from within the app they would get
an in-app action, typically going to a new screen of info, but for
those people who might just open up their own reader and scan it they
would get the url, and hence a page on the Kew site.
- the QR codes pointed to short URLs that we controlled, and hence we
could change their action
Unfortunately I left Kew soon after and I'm not sure if any evaluation
has been done, but there might be some useful data in there.
