The GS1 Databar is a family of barcodes based on the ISO/IEC 24724:2006 specifications to be used with the UCC/EAN system. The barcode is intended for encoding the identification numbers of items and their supplementary data. It is more compact and can carry more information than the current EAN/UPC barcode and is thus capable of identifying small items more easily.
As the EAN/UCC system is defined in a consistent manner around the world, it is extremely useful for the identification of trade items.
Important Dates
There is a GS1 mandate for all trade-item scanning systems to achieve the capability to read GS1 DataBar bar codes and GS1 Application Identifier System by January 1, 2010. This is also known as the GS1 global sunrise date.
