Scanning Composite Bar Codes
Composite Code is a combination of a 1D symbol (GS1 Da taBar, UPC/EAN or GS1-128) and a 2D symbol (CC-A,
CC-B or CC-C). When scanning a Composite Code:
•
Keep the scan pattern parallel to the symb ol’s rows.
•
Hold the scanner as still as possible.
•
Hold the scanner at an angle which does not ca use specular reflection.
•
Hold the scanner close for small symbols, and farther away for large symbols. Practice shows what works.
•
Aim the scan line at the middle of the 2D portion. The scan pattern rasters and decodes both the 2D and 1D
portion of the Composite Code.
