Still, the barcode regarded as standard today is a linear, 1D barcode inspired by Morse Code that consists of white and black lines of varying widths. Barcodes typically store product information such as price and weight, date of manufacture, expiration date, and the manufacturer's name.
A barcode symbol typically consists of five parts: a quiet zone, a start character, data characters (including an optional check character), a stop character and another quiet zone.
There may only be 12 numbers on a barcode, but when a laser from a computer scans a barcode it's actually scanning through a series of ninety-five evenly spaced columns! Computers only think in terms of binary, ones and zeros, so for each of these 95 columns, it either recognises it as black (one) or white (zero)
