The Tag reader then directs the user's mobile browser to the appropriate website. The print size can be varied to allow reasonable reading by a mobile camera phone for example, a Tag on a real estate sign might be printed large enough to be read from a car driving by, whereas a Tag in a magazine could be smaller because the reader would likely be nearer.Ī Microsoft Tag is essentially a machine readable web link, analogous to a URL shortening link: when read, the Tag application sends the HCCB data to a Microsoft server, which then returns the publisher's intended URL. Additionally, the code works in monochrome. Microsoft Tag is a discontinued but still available implementation of High Capacity Color Barcode (HCCB) using 4 colors in a 5 x 10 grid. Microsoft Tag logo indicating compatibility Microsoft claims that laboratory tests using standard off-the-shelf printers and scanners have yielded readable eight-color HCCBs equivalent to approximately 3,500 characters per square inch. HCCB can use an eight-, four-, or two-color (black-and-white) palette. Depending on the target use, the grid size (total number of symbols), symbol density (the printed size of the triangles), and symbol count (number of colors used) can be varied. HCCB uses a grid of colored triangles to encode data. Ours is more of a niche barcode where you want to put a lot of information in a small space.'" Technology "'It's more of a 'partner' barcode', he said. Quoted by BBC News in 2007, he said that HCCB was not intended to replace conventional barcodes. The technology was created by Gavin Jancke, an engineering director at Microsoft Research. It has been licensed by the ISAN International Agency for use in its International Standard Audiovisual Number standard, and serves as the basis for the Microsoft Tag mobile tagging application. ![]() 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. High Capacity Color Barcode ( HCCB) is a technology developed by Microsoft for encoding data in a 2D "barcode" using clusters of colored triangles instead of the square pixels conventionally associated with 2D barcodes or QR codes.
