The Global Trade Item Number ( GTIN), or previously known as EAN14, is the product identification structure in the GS1 (EAN/UCC) system.ISS Code 128 (International Symbology Specification Code 128) is the USS Code 128 barcode symbology with a new feature that allows the encoding of extended ASCII characters for non-English languages.USS Code 128 (Uniform Symbology Specification Code 128) is the published specification for the Code 128 barcode.
It was developed by the International Society of Blood Transfusion (ISBT) and the Working Party on Automation and Data Processing ( WPADP). ISBT-128is specifically designed for printing blood product barcode labels.Application Identifiers (AIs) define the purpose of the data in the symbol and how it is to be used. GS1-128(previously known as UCC-128 and EAN-128) is defined by GS1 and used to create several types of barcode symbols that include Application Identifiers.Several standards exist that dictate how Code 128 barcodes should be generated for certain implementations a few of these include: Various Standards for Code 128 Barcode Symbology The above Code 128 barcode symbol was created with the IDAutomation Barcode Image Generator. The complete Code 128 barcode consists of a start character, data digits, a modulo 103 check digit and a stop character. The Code 128 barcode may be complex to use because of the different character sets, which is the primary reason IDAutomation provides the Code 128 auto function, “Code128( )”, in several of the Font Tools, Components and Applications.
Functions are also provided in the barcode symbology to switch between character sets and encode Application Identifiers. Each printed barcode may have one of three different meanings depending upon which of the character sets are being used, with the availability of three different Code 128 start characters to program the initial character set. The Code 128 barcode is a high-density linear symbology that encodes text, numbers, numerous functions and the entire 128 ASCII character set (from ASCII 0 to ASCII 128.) It is commonly used for several implementations and is also referred to as ISBT-128, GS1-128, UCC-128, EAN-128 and USS Code 128.Ĭode 128 contains 106 different printed barcode patterns.
