| - | 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 [[dido:public:ra:xapend:xapend.a_glossary:a:application|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. The GS1 Composite symbology is one such symbology. The use of the symbology is intended to comply with the GS1 General Specifications. | + | Composite symbologies are a class of [[dido:public:ra:xapend:xapend.a_glossary:b:barcode|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.

| A GS1 Composite symbol consists of a linear component (encoding the item’s primary identification) associated with an adjacent 2D component (encoding supplementary 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 Composite symbol always includes a multi-row 2D component, for compatibility with linear and 2D imagers, and with linear and rastering laser scanners. | A GS1 Composite symbol consists of a linear component (encoding the item’s primary identification) associated with an adjacent 2D component (encoding supplementary data, such as a batch number or expiration date).
