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.
