This Symbology is also known as GS1 DataBar Expanded Composite Barcode, GS1 DataBar Expanded CC-A (CCA), GS1 DataBar Expanded CC-B (CCB), GS1 DataBar Expanded Composite A, GS1 DataBar Expanded Composite B, GS1 DataBar Expanded 2D Composite, GS1 DataBar Expanded Composite Component A, GS1 DataBar Expanded Composite Component B

In Barcode Composite Symbology, the linear component encodes the item's primary identification while the adjacent 2D Composite Component (abbreviated as CC) encodes supplementary data, such as a batch number and expiration date. The Composite Symbol always includes a linear component so that the primary identification is readable by all scanning technologies. The Composite Symbol always includes a multi-row 2D Composite Component that can be read with linear- and area-CCD scanners, and with linear and rastering laser scanners. The 2D Composite Component is printed above the linear component and both are separated by a separator pattern.

GS1 DataBar Expanded (formerly RSS Expanded) Composite Barcode is an GS1 DataBar Expanded linear barcode linked to a 2D barcode called CC-A or CC-B.

• GS1 DataBar Expanded is a variable length linear symbology capable of encoding up to 74 numeric or 41 alphabetic characters of AI Element String data. GS1 DataBar Expanded is designed to encode primary and supplementary data in items for Point-of-Sale (POS) and other applications. It has the same capabilities as a GS1-128 (UCC/EAN-128) barcode except that it is also designed to be scanned by omnidirectional slot scanners. It is designed for variable weight products, perishable products, traceable retail products, and coupons. The user data to be encoded into a GS1 DataBar Expanded barcode shall always consist of application identifiers and data fields that comply with the data standard of the GS1 General Specifications, formatted exactly as they would be for encodation into a GS1-128 (UCC/EAN-128) barcode. The GS1-128 (UCC/EAN-128) rules for concatenation of AI element strings, such as the use of a FNC1 to separate a variable length element string from the element string following it, shall be followed when encoding a GS1 DataBar Expanded barcode.
• The 2D Composite Component that can be liked to GS1 DataBar Expanded can be one of the following depending on the amount of supplementary data to be encoded:
  • CC-A: it is a variant of MicroPDF417 barcode and the smallest of the 2D Composite Components which can encode up to 56 digits.
  • CC-B: it is a subset of MicroPDF417 barcode which can encode up to 338 digits. Encoding systems normally automatically select CC-B when the data to be encoded exceeds the capacity of CC-A.

In order to get GS1 DataBar Expanded CC-A and CC-B Composite Barcode images, please follow these steps:

• Set the Symbology property to GS1DataBarExpandedCCA or GS1DataBarExpandedCCB or RssExpandedCCA or RssExpandedCCB
• Setting up dimensions and quiet zones:
  • Set the BarWidth property to 0.0208 (Value is expressed in Inches)
  • Set the BarRatio property to 3
  • Set the BarHeight property to 0.7072 (34 * BarWidth) or higher (Value is expressed in Inches)
• Set the Code property with the primary and secondary values separated by | char (See example below).
• Set the Text property to the Secondary Data which was encoded into the 2D Component

NOTE: The Primary Data must comply GS1-128 (UCC/EAN-128) data format i.e. application identifiers (AIs) + data fields

Code property = (01)93712345678904(3103)001234|911A2B3C4D5E (Primary Data = (01)93712345678904(3103)001234 and Secondary Data = 911A2B3C4D5E), Symbology property = GS1DataBarExpandedCCA, AddChecksum property = True will produce the following barcode image:
