Remarks

Finger position is used to speed up matching by skipping fingerprint pairs that cannot match due to incompatible position. SourceAFIS will return zero similarity score for incompatible fingerprint pairs.

This feature is optional. It can be disabled by using finger position Any which is default value of Finger for new Fingerprint objects.

A compatible fingerprint pair consists of two fingerprints with the same finger position, e.g. RightThumb matches only other RightThumb. Alternatively, compatible fingerprint pair can be also formed if one of the fingerprints has Any finger position, e.g. Any can be matched against all other finger positions and all other finger positions can be matched against Any. Two fingerprints with Any positions are compatible as well, of course.
