Specification. Schematic of a barcode (Code 128B). 1:quiet zone, 2:Start Code B, 3:data, 4:checksum, 5:stop. A Code 128 barcode has seven sections: Quiet zone. Start symbol. Encoded data. Check symbol (mandatory) Stop symbol. Final bar (often considered part of the stop symbol) Quiet zone.
23 Νοε 2012 · Code 128 is one of the more complex linear barcodes, with a greater capacity than Code 25 or Code 39, but requiring better quality images for reliable recognition. Key features: 4 different width of bar/space.
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.
ISO/IEC 15417:2007 specifies the requirements for the bar code symbology known as Code 128. It specifies Code 128 symbology characteristics, data character encodation, dimensions, decoding algorithms and the parameters to be defined by applications.
This International Standard specifies the requirements for the bar code symbology known as Code 128. It specifies Code 128 symbology characteristics, data character encodation, dimensions, decoding algorithms and the parameters to be defined by applications. It specifies the symbology identifier prefix strings for Code 128 symbols.
The most common use of Code 128 is for certain shipping labels, primarily as defined by GS1 in the GS1-128 barcode standard. Code 128 is defined in ISO/IEC 15417 Information technology - Automatic identification and data capture techniques - Code 128 bar code symbology specification.
Previously called the UCC-128, the GS1-128 barcode can carry up to 48 characters of information and can include a wide variety of attribute data such as batch/lot information, serial number, expiration date or country of origin.
