UPC AND EAN/JAN BAR CODES
UPC and EAN/JAN bar codes are typically used for
marking products with a unique code used to look up
prices and to track inventories of goods sold. They are
also used for store coupons, periodicals, and paperback
books. UPC and EAN/JAN bar codes are generally
rectangular, contain a fixed amount of data, and in most
cases are accompanied by human readable text printed
below them. For best results, this text should be an
OCR-A (resident font 2), a sans serif font (resident font 7)
or an OCR-B font.
