MatchLevel

When you need more detailed control on top of the UseCase, you can can tune individual checks by setting their MatchLevels. MatchLevels range from Level1 (the least strict) to Level10 (the most strict), and they can also be Disabled which means the check is completely skipped.

For example, you might be especially wary of photocopies, in which case you could set the photocopyMatchLevel to e.g. Level10.

MatchLevels are a tool for customizing checks that are on a gradient. Some checks are boolean, or not as granular, so they use different mechanisms for customization.

Note: These are fictional FRR values for demonstration purposes. Actual rates depend on the check, document types, image quality, and specific use cases.

The slider above demonstrates the relationship between MatchLevel strictness and False Rejection Rate (FRR). As you increase the strictness level, legitimate documents are more likely to be rejected due to minor imperfections or edge cases. Conversely, as you increase the strictness level, the check is able to catch more and more sophisticated fraud.
