- arch,
- tented arch,
- left loop,
- right loop, and.
- whorl.
What are the two most common minutiae?
Ridge endings and ridge bifurcations are the most commonly used minutia types since all other types of minutiae are based on a combination of these two types. Figure below shows some of the common minutiae patterns.
