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 during the
marking process that the markings are correctly applied and that readability is good enough
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.
