A barcode is an optical machine-readable representation of data, which shows data about the object to which it attaches. Originally, barcodes represented data by varying the widths and spacings of parallel lines, and may be referred to as linear or 1 dimensional (1D). Later they evolved into rectangles, dots, hexagons and other geometric patterns in 2 dimensions (2D). Although 2D systems use a variety of symbols, they are generally referred to as barcodes as well. Barcodes originally were scanned by special-optical scanners called barcode readers, scanners and interpretive software are available on devices including desktop printers and smartphones.

Before you Start What Information is Required to Generate a Bar Code?
1. ISBN Number - Each unique book product must be assigned a separate ISBN number. This is a 10-digit number assigned by the ISBN Agency.
2. Retail or List Price Information - To the right of the large bar code is a smaller bar code which contains the 5-digit price information. This symbol indicates either the retail price or that "no pricing information" (90000) is encoded.
3. Size of the symbol - The symbol occupies a space 2.00" x 1.25". This is the standard size used in most circumstances.
