Attention is drawn to the possibility that some of the elements of this document may be the subject of patent. The technology of bar coding is based on the recognition of patterns encoded in bars and spaces of defined.

There are numerous methods of encoding information in bar code form, known as symbologies. The rules defining the translation of characters into bar and space patterns,. The major benefit for the users of the GS1 system. Annex C gives an. Manufacturers of bar code equipment and users of bar code technology require publicly available standard. It specifies the Symbology Identifier prefix strings. Data content and the rules governing the use of this symbology are outside the scope of this International.

The following referenced documents are indispensable for the application of this document. For dated. For undated references, the latest edition of the referenced.

ASCII characters 48 - 57 inclusive, in accordance with. The four symbol types are described in 4. Symbol characters shall encode digit values in 7-module characters selected from different number sets. Annex D illustrates Table 1 graphically. The sum of the bar modules in any symbol character determines its.

Symbol characters in number set A are odd parity characters. Symbol characters in number sets B and. C are even parity characters. Number set C characters are mirror images of number set B characters.

Symbol characters in number sets A and B always begin on the left with a light module and end on the right. Symbol characters in number set C begin on the left with a dark module and end on the. A data character shall normally be represented by a symbol character. However in certain specific instances.

This technique is referred to as variable parity encodation. The normal guard pattern corresponds to the start and stop patterns in other symbologies. The special guard. The rightmost symbol character shall encode the check digit calculated in accordance with Annex A.

Since the EAN symbol comprises only 12 symbol characters but encodes 13 digits of data including the. The coding system for values of the leading digit is specified in Table 3. Figure 1 is an example.

These zeros are removed. Figure 4 shows an. D12 denote the GTIN data characters including check digit. D1 shall always be. D12 shall be the symbol check digit calculated according to the algorithm in Annex A. Let X1,. NOTE The number sets used to implicitly encode the check digit are shown below the digits in the zero-suppressed. Derivation of the 12 digit data structure from the characters encoded in the UPC-E symbol can be performed.

The symbol characters at positions P1, P Because they provide reduced security their use shall be limited to applications where rules in the. The add-on is. The add-on has no right guard pattern. It does not have an explicit check digit. Checking is done through the. The choice of number sets is linked to the value of the. A value v is determined by the following rules:.

It specifies the QR Code symbology characteristics, data character encoding methods, symbol formats, dimensional characteristics, error correction rules, reference decoding algorithm, production quality requirements, and user-selectable application parameters.

The stacked variations are two-row symbols. Composite symbologies are a class of bar code symbology, the principal distinguishing feature of which is that they comprise two, or more, components, each of which is a distinct symbol, but which contain a set of related data.

Typically one component is a linear symbol containing primary data, which can be read on its own in some areas of the application. The other component s is a two-dimensional symbol containing supplementary data which qualifies the primary message, and requiring all compo The need exists to identify the data carrier a reader detects in autodiscrimination environments.

The Symbology Identifier concept provides a standardized way for a device receiving data from a reader to differentiate between the data carriers. This identification is It specifies the Symbology Identifier prefix strings for Interleaved 2 of 5 symbols.

The technology of bar coding is based on the recognition of patterns encoded in bars and spaces of defined dimensions. Code is one such symbology. The rules defining the translation of characters into bar and space patterns, and other essential features of each symbology, are known as the symbology specification. In the past, symbology specifications were developed and published by a number of organiza Code 39 is one such symbology. The rules defining the translation of characters into bar and space patterns and other essential features are known as the symbology specification.

In the past, symbology specifications were developed and published by a number of organizations, resulting in c It specifies the Data Matrix symbology characteristics, data character encodation, symbol formats, dimensions and print quality requirements, error correction rules, decoding algorithm, and user-selectable application parameters.

It applies to all Data Matrix symbols produced by any printing or marking technology. Data Matrix is a two-dimensional matrix symbology which is made up of nominally square modules arran Users of bar code systems have experienced problems with poor read rates.

These read rate problems can sometimes be attributed to spectral gloss from either the substrate or the image or both. In many bar code applications, the position and orientation of the scanner relative to the bar code symbol can be directly controlled by the operator. In these applications, the presentation of the bar code symbol to the reader will usually be manipulated by the operator to achieve optimal performance.
