Dennis Hettema of OP3 that we talked about last year, a mobile tech company based in Netherlands, has launched ShotCode.com. The site promotes a free (for non-commercials) technology to create real world barcode-like hyperlinks that can be used by cameraphones to link consumers to web locations...
From the how they work page
The circular sequence of black and white blocks represents a url, any url you want, for example to your products website or a point of sale. The ShotCode reader understands this code and connects the end users mobile phone to your location in three clicks or less
End-users download special ShotCode software on their cameraphones. When they scan a ShotCode, the software contacts our servers and identifies the right url. We then broker a connection between the phone and your server, meaning neither you nor the end-user need to do any of the hard work.
Interesting tech no? First thoughts are that it might need a little tweaking if it takes a punter 3 clicks to reach the url, and that one company "brokering" the connection is not the greatest indication of long term success for a system such as this, but with a few choice deals with handset/software vendors and it could well take off...
Good luck Dennis!
