The smaller size of the RSS family is due to clever innovations in modern symbology design that allow RSS symbols to be

printed in various compact forms without compromising the performance of scanners designed to read them RSS Limited

and some forms of RSS-14 are designed to be read only by single-line hand-held scanners Other forms of RSS-14 and all RSS

Expanded symbols are designed to be read efciently by omni-directional scanners

Any member of the RSS family can be printed as a stand-alone linear symbol or as a composite symbol with an accompanying

EAN/UCC 2D Composite Component printed directly above the RSS Linear Component All RSS symbols encode a linkage ag

to indicate the existence of a 2D Composite Component

All of the RSS family is patented and placed in the public domain

RSS-14®

RSS-14 enables encoding of the full 14-digit UCC/EAN Global Trade Item

Number (GTIN), the EAN/UCC system for numbering of items Some

formats have omni-directional scanning capabilities The full height version

of RSS-14 has omni-directional scanning capability so that it can be scanned at retail point-of-sale

RSS-14 Truncated®

RSS-14 Truncated has a reduced height to t on small items that will be

read by hand-held scanners

RSS-14 Stacked®

RSS-14 Stacked is a truncated two-row format It has the same application

as RSS-14 Truncated but is used where a narrower symbol is needed

RSS-14 Stacked Omni-directional®

RSS-14 Stacked Omni-directional is a full-height two-row format It has the same application as the

full-height RSS-14 but is used where a narrower symbol is needed The separator pattern between

the two rows is designed to eliminate cross-row scanning errors

RSS Limited®

RSS Limited is designed for small item identication It does not have stacked or omni-directional

formats It encodes 14-digit item identication, but the 14th digit is restricted to indicator digit values

of 0 or 1 This allows an indicator of 0 for the smallest orderable item and indicator digit of 1 for small

packages of units such as hospital unit dose packages

RSS Expanded®

RSS Expanded encodes all EAN/UCC Application Identier Element Strings It has a

variable length with a capacity of up to 74 characters It has a binary-based encoding

scheme optimized for Application Identier Element Strings Special compaction

methods have been designed to decrease the symbol size for common

element strings such as variable weight and “best before” date

Unlike UCC/EAN-128, the RSS Expanded symbol has been designed to be

read efciently by omni-directional point-of-sale scanners
