Reduced Space Symbology
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 7883 can read four types of RSS bar codes.
RSS14
RSS-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).

RSS-14 Stacked
RSS-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. A typical use is marking produce in a
grocery store.
