Therefore, an Intermec computer that is configured to decode EAN bar codes can decode UPC, but the reverse is not true.
To define the EAN/UPC symbology, you set up to seven digits. 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.
The fifth, sixth, and seventh digits are optional. To set the sixth digit, you must set the fifth digit. To set the seventh digit, you must set all seven digits.
