Have you ever heard about bar codes that cellphones or PDAs could read? No? Well, they exist and are around for about 14 years!
Imagine that your CellPhone or PDA is capable of reading “Bar Codes”, and that these “Bar Codes” have more information than the typical product ID, well this is a reality for about 14 years. Of course that the “Bar Code” is not the typical one we are used to see in products, but instead it is a graphical representation of colors.
This technology has been around for 14 years, and is essentially a square with black and white squares that represent data.

Microsoft Tag is the answer from Microsoft based in the HCCB technology, is represented by a square with multiple color triangles.

In the battle between these 2 technologies, QR Code is way ahead due to its 14 years of existence and of appliance, but because HCCB is capable of having more data in a smaller Tag and it is Microsoft there is in my personal view a serious contendant to QR Code, and depending on Microsofts stategy, it might be a part of our life quicker than we though.
