NOTE

Scanning Composite Bar Codes

Composite Code is a combination of a 1D symbol (GS1 DataBar, UPC/EAN or UPC/EAN-128) and a 2D symbol
(CC-A, CC-B or CC-C). When scanning a Composite Code:
•
Keep the scan pattern parallel to the symbol's rows.
•
Hold the scanner as still as possible.
•
Hold the scanner at an angle which does not cause 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.
Aim at the center of the 2D portion
