Microsoft Tag Beta has been released that allows data to be stored in a graphical bitmap using shapes and colors is based on a whole new technology called High Capacity Color Barcodes (HCCBs). Microsoft Tags don’t actually store the information, all it stores is a unique ID which it then sends to Microsoft’s servers. This way, you can include much more information, and more variety of information, then if it was just on the tag itself. A nice side-effect of this is also the ability for publishers to gather reporting data on how many times it was seen.
To read these tags, Microsoft is making available a downloadable application to a handful of mobile platforms including Windows Mobile, J2ME, iPhone, Blackberry, and Symbian S60 phones. A camera and internet connection is obviously required. To get the application, point your phone’s browser to http://gettag.mobi.
The “tag maker” service is also available so anyone can create these tags.
