- Radial Loop. The radial loop is indeed one of the most frequent fingerprint patterns, but it’s not a one-size-fits-all design. It has its own variations, adding to the intrigue of fingerprint analysis.
- Ulnar Loop. The ulnar loop, as the counterpart to the radial loop, presents its own distinctive characteristics. Just like the radial loop, ulnar loops exhibit variations within their pattern, making fingerprint analysis a nuanced field.
- Double Loop. The double loop fingerprint pattern is a less common variation in the world of fingerprint analysis. Unlike the more prevalent radial and ulnar loops, the double loop exhibits a more intricate and distinctive configuration.
- Central Pocket Loop. Central pocket loop fingerprints offer a distinct and intriguing variation in fingerprint patterns. What sets them apart is the presence of a loop pattern that encapsulates a central dot or circular feature.
Fingerprint is a reproduction on a smooth surface of the pattern or design formed by the ridges of the first joints of the phalange of the fingers.
