Microsoft's multicolour bar code

Microsoft is hoping its newly developed multicolour bar code, which packs more information than traditional bar codes, will be used by DVD makers and others to help categorize their products.Microsoft's colour bar code is shown on a sample Xbox 360 disc of Viva Piñata. The bar code could be used to carry additional information about a product and help prevent counterfeiting.
