High Capacity Color Barcode

The High Capacity Color Barcode is a two-dimensional square "bar code" (actually using triangles rather than bars) developed by Microsoft and used as one of the formats for the Microsoft Tag system. As the name implies, the color of the triangles is relevant to their meaning, though there is also a monochrome version. Codes can be created with a two, four, or eight color palette.

These bar codes are generally used to store web links associated with products, signs, and the like, similar to the manner that QR codes are used. Though this is a Microsoft technology, reader apps exist for iOS and Android devices as well as those running Microsoft operating systems.
