No, not Queensland Rail. I wonder how their shares are travelling? I considered buying some when they were released. Maybe Colin or Diane are up to speed with them?
I was aware my current phone had a facility for reading QR codes. After owning it for over a year, I think, I decided to look at it. Ah, the QR code reader is a trial version from Telstra. I take that to mean they will want me to pay at some point. Barley that Charlie. I looked at Application shop with my phone. Goodie, a free one.
Downloaded and installed, now to try it. Oh, I don't have any QR codes lying around the house. I think I saw somewhere that they can read bar codes. The first things that came to hand was a box of Barbeque Shapes, kept only for visitors of course. It worked! It told me the Shapes came from Officeworks and cost $3.86. Well, they didn't. They came from Coles supermarket and cost $2. Never pay more than $2 for your Shapes and always send an email to the manufacturer about how much less spicy stuff they put on their Shapes.
Being a person with a great focus, I promptly forgot all about the QR code reader. A week or so later we were meeting a friend for lunch in town. As we waited in the building's foyer for her to come down from her office, we examined the sculptures on display. There was some information about each work and also a QR code. There was one work I particularly liked, so I whipped out my phone and read the code. It gave me a link to a website and there was all the information about the work, including the horrendous price of the work.
I have read some writers waxing lyrical about QR codes. While they may be vaguely useful, if they haven't really taken off by now, I doubt they will.
