9.1.1 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.
9.1.2 Add-on Symbologies
By default, the 2 or 5 digit add-on symbols with a UPCE, UPCA, EAN-8, and EAN-13
barcode is 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

The decoding of add-on symbols is typified by the following table, which explains the
process for EAN-13 symbols.
