Microsoft has developed a new type of two-dimensional code and  they have simply called Tag. We can see at a glance that there are two major differences with the rest of codes that we know (QR, DataMatrix, BiDi). These new tags are made up of triangles and they have color, that allows them to have a higher capacity.

The creators have designed this new type of code thinking in the devices that have focus problems  (as might happen with  low quality camera phones). 
Nowadays the service that they offer is free and it’s in a beta version.
