An ITF-14 bar code. The thick rectangular border is the Bearer Bar. ITF is often used for marking product ID numbers or other codes, of various lengths, on item cartons and multi-unit cases. One specific instance of this, standardized by GS1, is the ITF-14 bar code used to mark packages with Global Trade Item Numbers. In these uses, the ITF bar ...
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; The check symbol is calculated from a weighted sum (modulo 103) of ...
Industrial 2 of 5 could include optional checksum character which is added to the end of the barcode. Industrial 2 of 5 features: character set is a number (0-9); encoding density low: barcode length on 50% longer than Interleaved 2 of 5 symbology and on 172% than Code 128; variable length of symbol; can include optional checking character.
A UPC barcode. The Universal Product Code (UPC or UPC code) is a barcode symbology that is used worldwide for tracking trade items in stores.. The chosen symbology has bars (or spaces) of exactly 1, 2, 3, or 4 units wide each; each decimal digit to be encoded consists of two bars and two spaces chosen to have a total width of 7 units, in both an "even" and an "odd" parity form, which enables ...
Despite the fact that ITF-6 barcode isn’t included into ISO standards, it is widely used as add-on to encode items quantity in package or item weight.At this time, it is used only with ITF-14 (Global Trade Item Number), but up to 2010 it was used with standardized only in Japan ITF-16 (Extended Symbology for Physical Distribution).
In the UK alone, the introduction of the barcode in the retail industry has resulted in savings of 10.5 billion pounds per year. [ 1 ] [ 9 ] Some of the barcodes that GS1 developed and manages are: EAN / UPC (used mainly on consumer goods), GS1 Data Matrix (used mainly on healthcare products), GS1-128 , GS1 DataBar , and GS1 QR Code.
Matrix 2 of 5 barcode. Matrix 2 of 5 (also known as Code 2 of 5 Matrix. [1]) is a variable length, discrete, two width symbology. Matrix 2 of 5 is a subset of two-out-of-five codes. Unlike Industrial 2 of 5 code, Matrix 2 of 5 can encode data not only with black bars but with white spaces.
The data message in DotCode is represented with data codewords from 0 to 112 which are encoded with 5-of-9 binary dot patterns. DotCode supports the following features: [ 2 ] : 5.2.1 Natively encodes digits or ASCII charset (between 0 and 127) with A, B and C code sets and extended ASCII values (128 to 255) with Upper Shift;
