A.2 Example of barcode symbologies
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. Always refer to the relevant
standard ISO/IEC 15421 for size and resolution require-
ments when creating patient or operator barcodes.
When creating patient or operator barcodes, always
adhere to the applicable international IEC/ISO standards
for the respective barcode symbology. In particular, ensure
that barcode size and print quality (as defined in ISO/IEC
15421) are adequate. Inadequate print size and/or quality
may lead to erroneous decoding.
EAN 13 barcodes, although widely used in retail, are
less recommendable for patient/operator barcodes. If
used, they demand the very highest quality standards
of barcode creation and reproduction.
