UPC/EAN (Universal Product Code / European
Article Numbering) is probably the most widespread barcoding system.
EAN codes (8 and 13 digit) are used in all European countries, while
UPC ones (8 and 12 digit) are more frequent in North America. The
encoding scheme for both barcode types is the same (12-digit UPC
is a subset of 13-digit EAN). These barcodes can carry numeric information
only.
The generator supports EAN-13, EAN-8, UPC-A,
and UPC-E barcodes, including checksum generation. Type of the generated
barcode is deduced from the input data or specified explicitly as
a parameter to the stylesheet.
