2D barcodes gone high capacity and color

“High Capacity Color Barcode (HCCB) is the name coined by Microsoft for its proprietary technology of encoding data in a 2D “barcode” using clusters of colored triangles instead of the square pixels traditionally associated with 2D barcodes.^[1] Data density is increased by using a palette of 4 or 8 colors for the triangles, although HCCB also permits the use of black and white when necessary. It has been licensed by the ISAN International Agency for use in its International Standard Audiovisual Number standard,^[2] and serves as the basis for the Microsoft Tag mobile tagging application .” – Wikipedia

Microsoft is actually doing something quite interesting and quite disturptive
