EAN/UPC
Today, barcodes that use EAN/UPC symbology (including the UPC-A, UPC-E, EAN-13 and EAN-8 barcodes) are the only barcodes allowed for products scanned at retail point of sale. EAN/UPC barcodes ensure that all products are properly identified at any retail point of sale, speed up data collection, and result in more accurate data that can be used by trading partners.
