“withAddon” options. There are 4 options – one for each symbology: UPCEwithAddon, UPCAwithAddon,
EAN8withAddon, and EAN13withAddon. The decoding of add-on symbols is typified by the following table,
which explains the process for EAN-13 symbols:
Value of flags Mode Behavior
EAN13 EAN13withAddon
Auto-discrimination If add-on symbol is present, then it is
also decoded; otherwise only the EAN-
13 symbol is decoded.
true true
With add-on Only EAN-13 barcodes with 2 or 5
add-on symbol are decoded.
false true
Without add-on The add-on symbol is ignored. true false
The add-on symbol is appended to the EAN-13 barcode. The process is similar for UPCE, UPCA, and EAN-8
barcodes. Note that all the UPCE, UPCA, EAN-8, and EAN-13 formatting and conversion options are in effect.
The following table should help explain the effect of various options for EAN-8 barcode 12345670 + 12:
Barcode

1234567012 true

The add-on symbol neither contains check digit nor a terminating guard band. Every effort has been made to
reduce the decoding error; however, it is likely to decode a partial scan of a 5-digit add-on symbol as a 2-digit
add-on symbol. It is strongly recommended that the security level be set to minimum 2 while decoding add-on
symbols.
Since the decoder takes a conservative view on the add-on symbols, it is likely that the add-on symbol will be
missed in the auto-discrimination mode. Auto-discrimination mode should then be avoided.
