The barcode samples shown here are for illustration
purposes only. If printed out, they can be used to check
the barcode scanner. However, they are not meant to be
used as a reference for size or resolution of real patient
or operator ID barcodes. When creating patient or
operator barcodes always refer to the relevant standard
ISO/IEC 15416 and 15415 for size and resolution require-
ments and to the specification listed below.
WARNING
Avoidance of incorrect EAN 13 and Interleaved 2/5
barcode readings
EAN 13 and Interleaved 2/5 barcodes, although widely
used, are not recommended for patient/operator bar-
codes. If an EAN 13 or Interleaved 2/5 barcode is read
incorrectly, this may lead to patient misidentification and
therefore to inappropriate therapy decisions. If used
nonetheless:
■ make sure that the very highest quality standards of
barcode creation and reproduction are applied
■ for EAN13: do not use the start sequences 978 (ISBN)
and 979 (ISMN) as they will be ignored as a part of
any ID code
