
FNC1 (Variable length AIs must start with a FNC1 character)

Multiple AI support (unlimited number of AIs in a bar code)

Date encodation (AIs with dates will be tested for proper formatting)

GTIN prefixes (Some AIs require a prefix digit in the GTIN),


Mandatory pairs of element strings. These are AIs
that require a second AI to be in the same symbol.
