Bar code confidence
Bar codes cannot be partially misread; they are either located or not located. The confidence value assigned to a bar code on a document depends on whether or not it is the only bar code on the document.
If a document contains one bar code only, it is assigned a confidence level of 100% if located. If there is more than one bar code, all located bar codes receive a confidence level of 50%. The first encountered bar code is usually the extraction result, even if the confidence is no higher than the other bar codes on a document.
If a document has multiple bar codes, and you know that the bar code to use has a different type, ensure that the other bar codes are not located by restricting the bar code type to only locate the required bar code.
If the required bar code is horizontal and the others are vertical, restrict the orientation to "Left to right". Also, if the bar codes have different lengths, restrict the length.
