Google Celebrates the Invention of the BarCode
The Barcode was invented 57 years ago today. October 7, 1952 the official patent was issued US Patent 2,612,994.
The Washington Post reports The barcode on the Google homepage is Code 128 encoded, which is a standard way of encoding ASCII character strings (ie. A-Z, a-z, 0-9, etc.) into a barcode. It would be safe to assume that Google used their own open source barcode project, ZXing, to generate the barcode. The same library is used in Android for barcode recognition.
