Fingerprint Phone Case

Fingerprints are unique patterns of ridges and valleys on the skin of the fingertips. They are used for identification because no two fingerprints are exactly alike, even among identical twins. Fingerprints are formed during fetal development and remain unchanged throughout a person's lifetime. They are often used as a form of identification in criminal investigations and for personal identification in security systems. Fingerprints can be captured using ink or digital scanners, and are analyzed using a process called fingerprint identification.
