individual Wikipedia articles. These tags can then be attached to the physical objects mentioned in the Wikipedia articles. Reading a tag with a camera phone will then retrieve an article from Wikipedia and display it on the phone screen, creating a "Mobile Wikipedia". An alternative to using 2d barcodes is to apply computer vision techniques to identify more complex patterns and images. Companies like kooaba, Daem, or Neven Vision (acquired by Google in 2006) develop image recognition platforms to turn any image into object hyperlinks. Microsoft has developed a system for creating hyperlinks using image matching. Google is now planning to tag 100,000 businesses in the United States with QR codes.
