Microsoft has developed a nanotechnology based color barcode system which will be attached to DVDs. Nanotechnology is being used for controlling counterfeiting. In this case nanoparticles will be embedded into the code for countering piracy. To be integrated into the code and packaging structure the material will be illuminated under a particular frequency of light and a handheld digital reader will be used for detection. Even cell phones with cameras and webcams will be used for interacting with the barcodes.

Now it will offer more security and even link to any bonus feature or movie trailer. There are some cons of using these nanotechnology labels since besides requiring color even high quality printing is required which might be expensive for some. Also, special scanner is needed and standard bar code scanners would be rendered redundant. As of now, these codes would be used in case of high value commercial media such as video games, movies and other recordings.
