Settings tab - Properties of Bar Code Locator window

Use the following settings to enhance bar code recognition:

Type

This group contains a list of bar code types. At least one bar code type is required.

The value for this setting is set to Auto detect by default.

Use the default value only if you do not know the expected bar code types. This is because the Auto detect value negatively impacts the performance and accuracy of bar code recognition and includes only a subset of the full list of available bar code types.

For the best results, select one or more specific bar code types from this list and then use the page number or a region to narrow down the bar code location. This ensures that recognition is more likely to find a bar code. If you are recognizing multiple bar codes in multiple locations, use a separate Bar Code Locator for each bar code, restricting the search area using specific page numbers and regions.

When Auto detect is selected, all other bar code types are unavailable. If you clear the Auto detect value, select one or more of the bar code types. When testing the locator, any recognized bar codes are displayed on the Test tab along with their bar code type, confidence, value, and page location.

You can select only one of the Code 39 or Code 39 without start/stop character bar code types.

Enable checksums

Select this setting to help reduce errors if the bar code is misinterpreted.
