MS Tag seems to be an interesting idea. I have known some similar technologies (3D bar codes) so I still don't get the real advantages of this one since 3D tags can be produced and read for free a long time ago. Maybe it is the integration with each mobile phone browser that MS will be providing for free.
MS tag allows people linking easily to web contents only by scanning (on phones) the image displayed on catalogs, wall advertisements, etc. This will avoid you having to take note of a link or having to type it later on in your browser. Typing by hand a link is cumbersome. Even short ones.
You login into the site (MSN credentials will work) and you can start creating your tags by providing a sentence and an URL to what you want to link to. After that the tag is listed on a grid. On the render grid column you can create several versions of the tag to embed in your site, publishing magazines, etc.
Tip: The first time you try to render, a different popup appears that forces you to read the publishing guidelines. After doing this for the first time, the next time you press render a popup menu with options to render the currently selected tag line apears: PDF, png, tiff, jpg, etc. are some options available.
MS tagging publisher guidelines can be found at: http://www.microsoft.com/tag/content/why/guidelines.aspx
The bad news is that you'll have to pay for each generated coloured tag when the service goes off Beta.
Also, I've tried the above logo with the iPhone. Open the MS Tag app, photographed the logo on my laptop LCD, chose "Use" action and there you go: A browser page with this blog on the iPhone browser appeared. Nice and sweet and with no sweat!
I have tested it and it works very well: You open the MS Tag app in the iPhone, it opens the Camera shooter. You shoot the image in your LCD and select "Use" and it opens the Safari browser in the right place. Very interesting!
ResponderEliminarNote: If you don't have the app installed first open the iPhone browser and then go to the address indicated in one of the tags with full instructions.
