What Is Fingerprint Classification?

The basic type of fingerprint is the nomenclature of fingerprints. According to the different structures of the internal pattern of the fingerprint, the fingerprint can be divided into four types: arched pattern, crenellated pattern, bucket pattern, and mixed pattern: (1) arched pattern; (2) creped pattern. There is more than one pattern in the center of the internal pattern. The sacral line is surrounded by more arched lines on the upper and both sides, and the wavy lines and horizontal straight lines serve as the root baseline. (3) Bucket pattern. There is more than one ring line, or spiral line, or Qutong line in the center of the internal system. The upper and both sides of the line are surrounded by more arched lines, and the lower part is surrounded by wavy and horizontal lines. Wait for the combination of the three systems. (4) Mixed patterns, where the above three types of single patterns cannot be included, but the pattern composed of a mixture of two patterns, or some peculiar forms, which can not be classified into the patterns of bow, cymbal, and bucket patterns, are collectively referred to as For mixed patterns. ^[1]
