Nat
20、ional bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interes
21、t. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. International Standards are drafted in accordance with th
22、e rules given in the ISO/IEC Directives, Part 2. The main task of the joint technical committee is to prepare International Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard require

ISO and IEC shall not be held responsible for identifying any or all such patent rights. ISO/IEC 24723 was prepared

25、(E) vi ISO/IEC 2010 All rights reservedIntroduction 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 compon
26、ent 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 components to be read to extract the complete message
27、. The GS1 Composite symbology is one such symbology. The use of the symbology is intended to comply with the GS1 General Specifications. A GS1 Composite symbol consists of a linear component (encoding the items primary identification) associated with an adjacent 2D component (encoding supplementary
28、data, such as a batch number or expiration date). The GS1 Composite symbol always includes a linear component so that the primary identification is readable by all scanning technologies, and so that 2D imagers can use the linear component as a finder pattern for the adjacent 2D component. The GS1 Co
29、mposite symbol always includes a multi-row 2D component, for compatibility with linear and 2D imagers, and with linear and rastering laser scanners. GS1 Composite symbols are intended for encoding identification numbers and data supplementary to the identification in accordance with the GS1 General
30、Specifications. The administration of the numbering system by GS1 ensures that identification codes assigned to particular items are unique world-wide and that they and the associated supplementary data are defined in a consistent way.
