Range of application
●
Different types of code can be read in an image.
●
Available for data matrix codes that can be read with standard methods.
●
The maximum number of codes and the code types used are specified when the program
is saved. Depending on the configuration, the actual number and the code types found in
processing mode can vary.
●
Due to the multiple decoding, the processing time is extended approximately proportional
to the number of codes per image.
Example
With this function, you can record a one-dimensional code and a data matrix code on
packaging with one image acquisition and output the read result of both codes in the same
cycle.

Overview
Verification
The readability of a 1D or 2D barcode will never be better than at the time the barcode
leaves the marking device. With the help of code verification, it is possible to make sure that
the markings are correctly applied during the marking process and that readability is good
enough so that it will remain ensured throughout the entire life cycle. Verification makes sure
that corrections can be made to the marking procedure before it leaves a range of tolerance
and produces unusable or incomplete markings.
