fingerprint patterns

Fingerprint patterns are the unique ridges and valleys found on the surface of our fingertips. These patterns are formed during fetal development and remain constant throughout a person's life. The main types are loops, whorls, and arches, each with distinctive ridge arrangements. These patterns are used in forensics and security because no two individuals, even identical twins, share the exact same fingerprint pattern. They provide a reliable method for personal identification due to their uniqueness and permanence.
