What is palmar flexion crease identification primarily used for?

Palmar flexion crease identification is primarily used for personal identification due to the unique and consistent patterns of these creases on an individual’s palms. These creases, which form during fetal development, can be used in conjunction with fingerprints to provide additional biometric data for individual identification. While it is true that fingerprints can vary between individuals and can change slightly over time, the palmar flexion creases remain relatively stable, making them a reliable feature for distinguishing one person from another.

The use of palmar flexion creases is particularly important in forensic science because it adds another layer of personal identification alongside the more commonly examined fingerprint patterns. When combined, these features can enhance the accuracy of identifying individuals in criminal investigations or missing person cases.
