palm print

A palm print is an impression of the lines and wrinkles on the palm of a hand, used for identification. The skin on the palms, like other parts of the body, has unique patterns of ridges and grooves called dermatoglyphics. These patterns are established before birth and are unique to each individual, making them an infallible signature for personal identification. While fingerprints are more commonly used due to ease of collection, any ridged area of the hand or foot can serve for identification. The study and use of fingerprints for identification is known as dactyloscopy.123
