UPC-A 
Universal Product Code (UPC)/European Article Numbering 
(EAN) symbologies are fixed-length, numeric, continuous 
symbologies that use four element widths. A computer that is 
configured to decode EAN bar codes can decode UPC, but the 
reverse is not true. UPC code is a subset of EAN code. 
The supplemental portion of a UPC or EAN label is a weak 
symbology and can be missed by the scanner for several reasons. 
In situations where supplementals are known to be present, 
reading just the main symbol can be prevented until a valid 
supplemental is found. When using a laser scanner, performance 
degradation is not noticeable. 
You can configure the following options for UPC-A: 
•  Enable 
•  Send leading digit 
•  Send check digit
