How do barcodes work?
Different combinations of bars and spaces are used to encode characters into barcodes. Differences in light and dark and the width of the elements are the variables used for encoding. The barcode reader illuminates the symbol and measures the amount of light that is reflected back. The reader determines the pattern of light and dark or wide and narrow, then compares it to the encoding table for that type of barcode (called a symbology) and decodes the symbol.
