RSS/Composite:
Combined Power
RSS bar codes can be combined with a unique 2D Composite
Component to form an entirely new class of symbology called EAN/UCC
Composite Symbology. The result is a big step towards identification
and supply chain management capabilities for those limited by today’s
solutions.
Composite Symbology consists of a linear symbol accompanied by
a two-dimensional symbol printed on top of the linear. This can
be any existing linear symbology including RSS. A remarkable characteristic
of this technical solution is that the linear symbol acts as a "finder
pattern" for the 2D symbol. This permits to keep the 2D component
very small.
RSS-14
+ 2D Component
When
the linear bar code is an RSS, the link between the linear and the
2D component is established in the symbol itself. Consequently,
a scanner cannot decode the 2D component without decoding simultaneously
the linear component.
UCC/EAN-128
+ 2D Component
Potentially,
a 2D component could be used in conjunction with an UCC/EAN-128
bar code representing for example the Application Identifier of
the Serial Shipping Container
Code (SSCC).
EAN/UPC
+ 2D Component
A
2D component could also be linked to an EAN/UPC bar code symbol.
In that case, there would not be any link between the linear and
the 2D components.
TYPES
OF 2D COMPONENTS
Three
types of 2D components have been defined as follows:
- Composite
Component A (CC-A): A new 2D symbology capable of encoding up
to 56 characters.
- CC-B:
A subset of Micro PDF (Portable Data File) used to encode between
56 and 200 characters.
- CC-C:
A "regular" PDF 417 symbol used to encode more than
200 characters.
