Recently I saw a symbol on the side of the pepsi can that looked something like this and all it said with it was want to know more... visit us, with some url back to pepsi's website.

I thought that was all a bit odd, but unusually for me I disregarded it as some kind of new marketing game I wasn't interested in.

Today however I was starting to catch back up with months of missed Google reader posts, saw a similar thing on Matt Cutt's blog where he was talking about the chart types that the google charting API can produce and found out these things are called QR codes.

And apparently "QR codes can be read by any device that has the appropriate software installed. Such devices range from dedicated QR code readers to mobile phones."

When I received my Nokia E71 a year or so ago I noticed it had bar-code reader software pre-installed on it, but had no idea what that was really for, until now, it's for reading codes like this!

So why not try it yourself. If you have a phone with bar code reader software built in and want to give it a try, point it at the screen and find out what this says:

If you have an interest in having these codes produced please get in touch!
