GS1 DataBar
GS1 Databar, formerly Reduced Space Symbology (RSS) permits more data to be
recorded in a smaller physical space. This is accomplished by encoding the data in
large symbol characters rather than encoding each data character separately. Also, no
quiet zone is required around the symbols. The RealScan 74 can read four types of
GS1 Databar barcodes.

GS1 Databar–14
GS1 Databar–14 is a linear symbology that encodes 14 UCC/EAN digits. This
structure provides four segments that can be scanned and decoded separately, then
reconstructed. The total symbol contains 96 modules combined into 46 elements (bars
and spaces).

GS1 Databar–14 Stacked
GS1 Databar–14 Stacked is a 2–row format. The bottom row is higher than the top row
and the two are separated with a separator pattern. The stacked format is used when
not enough linear space is available. An example use is marking produce in a grocery
store.
