GS1 Databar Limited
GS1 Databar Limited has the same data characteristics as the GS1 Databar Omni-
directional barcode, except that it may only include values up to 4 trillion. This symbology is
specifically designed to be read by wands and handheld laser scanners. Omni-directional
scanners can not read it efficiently.

GS1 Databar Expanded
GS1 Databar Expanded is a variable length symbology capable of encoding up to 74
numeric or 41 alphabetic characters. This symbology does allow for the linkage flag, which
determines if there is a 2D composite barcode associated with the linear barcode. Despite
the possible length of the symbol, it can still be omni directionally read by suitably
programmed laser point-of-sale scanners because the symbol can be decode in up to 22
segments and then reconstructed.
