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. Also, if the bar codes have different lengths, restrict the length.
If you cannot eliminate the unwanted bar codes from your document using the Type or Length settings on the Properties of Bar Code Locator window, use Regions to restrict the area of a document that is searched for the bar code. This works best if the bar codes are consistently located on a document.
