Introduction
The EAN. UCC Reduced Space
Symbology (RSS) family contains three linear symbologies to be used
within the EAN. UCC system. The use of the symbology is inteended
to comply with the EAN International (EAN) and Uniform Code Council.
Inc. (UCC) application guidelines.
RSS-14 encodes the full 14
digit EAN. UCC item identification in a linear symbol that can be
scanned ominidirectionally by suitably programmed point-of-sale barcode
scanners. RSS Limited encodes a 14 digits EAN.UCC item
identification with Indicator digits of zero or one in a linear symbol
for use on small items that will not be scanned at the point-of-sale.
RSS Expanded encodes EAN.UCC item identification plus supplementary AI
element strings such as weight and "best before" date in a linear symbol
that can be scanned omindirectionally by suitably programmed
point-of-sale bar code reader.
RSS-14 Stack is a variation
of the RSS-14 symbology that is stacked in two rows and is used when the
normal symbol would be too wide for the application. It comes in
two versions, a truncated version used for small item marking
applications and a taller ominidirectional version which is designed to
be read by
ominidirectional scanners RSS Expanded can also be printed in
multiple rows as a stacked symbol.
Any member of the RSS family
can be printed as a stand-alone linear symbol or as a Composite symbol
with an accompanying 2D Composite Component printed directly above the
RSS linear component.
EAN.UCC RSS bar code symbols
are intended for encoding identification numbers and data supplementary
to the identification. The administration of the numbering system
by EAN and UCC ensures that identification codes assigned to particular
items are unique worldwide and that they and the associated
supplementary data are defined in a consistent way. The major
benefit for the users of the EAN scanner is the availability of uniquely
defined identification codes and supplementary data formats for use in
their trading transactions.
