Bookland EAN vs. EAN-13
Bookland EAN, which includes ISBN, ISSN, and ISMN, is supported by the KDC. This group of
symbologies is essentially an EAN-13 barcode with fixed prefixes; 977 for ISSN, 978 for ISBN,
and 979 for ISMN. If EAN-13 and Bookland EAN are both enabled, Bookland EAN takes
precedence. Bookland EAN does not have any options. The Bookland EAN barcode does not
contain any groupings – that is, there are no hyphens or separators. Thus, the ISBN 957-630-
239-0 is transmitted as 9576302390.
Add-on Symbologies
By default, the 2 or 5 digit add-on symbols with a UPCE, UPCA, EAN-8, and EAN-13 barcode
are neither decoded nor transmitted. Transmission for these specific symbologies is enabled
by setting the appropriate
withAddon options. There are 4 withAddon options, one for each
symbology:

UPCEwithAddon

UPCAwithAddon
 EAN8withAddon

EAN13withAddon
The decoding of add-on symbols are defined by the following table, which explains the
process for EAN-13 symbols.
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 12 12.
