Fujitsu's Invisible Cameraphone Hyperlinks

[NEAsiaOnline] Fujitsu has developed a method for invisibly embedding information into printed images as small as one centimeter square. By printing a series of imperceptible yellow dots into an image, up to 12 digits of numeric information can be hidden, allowing a company to embed a phone number or encoded URL. Then, by taking a picture of the image with a cameraphone or PDA, special software can decode the numbers and call the company's phone number or look up their webpage. [via]

"Fujitsu Laboratories expects the following applications: users can make a phone call by reading a phone number from a picture on a name card they obtain from a business; download ring melody data for their mobile phone by scanning a picture on a CD jacket they like; and collect information on a shop/restaurant while reading about them in a magazine."
