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.

RSS Expanded

RSS Expanded is a variable length linear symbology. It can encode 74 numeric or 41 alpha characters. RSS Expanded can be scanned and decoded in up to 22 segments and then reconstructed.

RSS Expanded Stacked

RSS Expanded Stacked is similar to RSS-14 Stacked except it uses the RSS Expanded format for creating the symbol.
