Coding Rule Violation (CRV) means violation of coding rules. All coding is subject to certain rules and guidelines
that must be followed. For example, bar coding according to Code 2/5
requires that a character consists of three bars and two gaps and that two bars or gaps are wider than the remaining three. If such conventions are disregarded, it is a Coding Rule Violation (CRV), which inevitably leads to misinterpretations. To avoid CRVs, the generation of codes is supported by appropriate software.
