The fingerprint type that has ridges that enter from one side of the fingerprint and leave from the other is called a loop. In a loop fingerprint, the ridges enter from one side of the pattern and form a curve before exiting from the opposite side. This type of fingerprint is the most common, accounting for around 65-70% of all fingerprints.
