Do any of you recognise the above image?  Do you know what it does?  Do you know what to do with it?

QR codes are springing up all over the place.  You can find them on your telephone bill, on DVD stands in your local supermarket, the leaflets that Lightwater Valley hand to your youthgroup as they enter the theme park or even on bottles of wine!  What the heck is it?

It is an image that a smart phone can scan that links you to a web address without having to type it in.  On the DVD stand it takes you to a video trailer for the film they are selling.  The leaflet they were handing out takes you to the Lightwater Valley home page.

The good thing about QR codes is that they are free to use for anyone.  Simply go to a QR code generator such as http://qrcode.kaywa.com/ and type in your web address.  Hey presto.  Totally open source and free at the point of access.

If you look at the poster I made for The Rock Mass @ Biblefresh Wakefield you will notice that I’ve put a QR code on the bottom corner.  I also put them on the promo material for Silverthorn.

So what do you think about them?  Is it something we should be using?  If you’ve never heard of them, try downloading a QR reader app to your phone and try scanning this one.  See what you think.
