Barcodes encode data as a series of parallel lines of varying widths and spacings that optical scanners can read in milliseconds. They are the backbone of retail point-of-sale systems, inventory management, logistics, and parcel tracking worldwide.
Code 128 is a high-density barcode that encodes the full ASCII character set. It is used in shipping labels, warehouse management, healthcare barcodes (GS1-128), and any application needing alphanumeric data.
EAN-13 (International Article Number) is the standard for retail products sold in Europe, Australia, Asia, and most of the world. It encodes a 13-digit number that identifies the country, manufacturer, and product.
UPC-A (Universal Product Code) is the North American retail standard, encoding a 12-digit number. Every UPC-A is a subset of EAN-13 (with a leading zero).
