Microsoft quietly released Microsoft Beta Tag, which he says is colored leap in mobile barcode technology. This is actually a fairly simple system that allows a printed image to be translated by a camera phone into a URL.
Tag format Microsoft uses a system of colored triangles so that the amount of data that can be stored in the same space is greater than can be accommodated by a black triangle and white. Microsoft is smart enough to realize that in order to be useful, Tag-it system should still work even if the camera that captured images of the Tag is bad, as is the case in many mobile phones. Some good error correction algorithms to ensure that tags are disabled it is still readable. Microsoft is also aware that the size of 5/8 inches square for the Tag-it is consistent with the targeted neighborhood.
