22. EAN -128 / GS1 Databar and Application Identifier

Input the Application Identifier in EAN-128 Barcode

QLabel-IV supports Application Identifier (AI) in EAN-128 barcode. AI is a series of codes that can contain
pre-defined data type and actual data content in single data string. Each AI has 2 ~ 4 digits numeric Prefix in
front of the data to tell what the data means. For example, (11) represents the production date that should
conform to the format of "n2+n6". "n2" refers to the Application Identifier "11" and "n6" refers to the actual data
content in "YYMMDD" format. There are more than 100 Application Identifiers are defined in similar way. For
more details about Application Identifiers, please refer to the specification documentation of Application
Identifiers.

When inputting data with barcode type of EAN-128, QLabel-IV will check whether the input data conform to the
rule of AI. If the input data is following one of the AI definitions, QLabel-IV will then automatically bracket the
Application Identifier in human readable text (the actual barcode data remains the same). For example, input
"11090227" in data field, QLabel-IV will transfer it to "(11)090227" since it conform to the "n2+n6" rule of "(11)
production date".

If the input data is "1120090227", QLabel-IV will determine that it is not Application Identifier because it begins
with Application Identifier "11" but not in "n2+n6" format. Therefore, QLabel-IV will not transfer the input data to
the display type of AI.
