Ridge Characteristics (Minutiae)
Ridge endings, bifurcations, enclosures, and other ridge details, which must match in two fingerprints in order for their common origin to be established
A fingerprint made by the deposit of oils and/or perspiration, it is invisible to the naked eye.
A class of fingerprints characterized by ridge lines that enter from one side of the pattern and curve around to exit from the same side of the pattern.
A class of fingerprints that includes ridge patterns that are generally rounded or circular in shape and have two deltas.
