Loop Fingerprint Pattern: 5 Rules and 4 Types With Images
Loops are the most common fingerprint patterns, accounting for 60%-70% of all patterns, where ridges enter from one side of the finger, make a U-turn around a central point (core), and exit on the same side of the finger. This characteristic U-turn of the ridge is called a “recurve”. However, all U-turn patterns are not …
