*Code 128 is a very high-density barcode symbology. It is used for alphanumeric or numeric-only barcodes. It can encode all 128 characters of ASCII and, by use of an extension character (FNC4), the Latin-1 characters defined in ISO/IEC 8859-1 [[File:262px-Code_128B-2009-06-02.svg.png|center|150 px]]<br><br><br> | *Code 128 is a very high-density barcode symbology.
