Mobiles & QR codes

I tried Curtin's library catalogue on my iphone & it's very easy to use. Even the covers of books came through with the call number on the first screen. How much time could this save students on public transport on the way to Uni?? I don't know any students without a mobile but not everyone has an iphone...they are getting cheaper though and mobiles are so important now socially that getting the latest is a priority! QR codes could be useful, how about a competition for O Week? Could we be ready in time? We are always looking for something cool & new in orientation. Testing a Librarian is a natural progression from our current email format. I would volunteer to trial it! I remember thinking 10 years ago that I didn't need a mobile phone. Everyone laughs at me now if I admit to that...
