Moreover, the texture prevents things from slipping and sliding that would have naturally happened if the skin was smooth. Fingerprints afford an infallible means of personal identification, because the ridge arrangement on every finger of every human being is unique and does not alter with growth or age. Galtons system served as the basis for the fingerprint classification systems developed by Sir Edward R. Henry, who later became chief commissioner of the London metropolitan police, and by Juan Vucetich of Argentina. The ulnar loop is a loop-shaped pattern that resembles a waterfall which is flowing towards the little finger.

Through the AFIS gateway, users receive the results of their checks very quickly: The automated process means the database can make more than 3,000 comparisons per day. There are several variants of the Henry system, but that used by the Federal Bureau of Investigation (FBI) in the United States recognizes eight different types of patterns: radial loop, ulnar loop, double loop, central pocket loop, plain arch, tented arch, plain whorl, and accidental.

A fingerprint is a unique way of identifying a person. Dactyloscopy, the technique of fingerprinting, involves cleaning the fingers in benzene or ether, drying them, then rolling the balls of each over a glass surface coated with printers ink. The fingerprint images can then be photographed, marked up for distinguishing features by latent fingerprint examiners, and used to search an automated fingerprint identification system (AFIS). In the past century, forensic investigators have universally accepted fingerprinting as a reliable identification method, which relies mainly on pictorial comparisons. For example, the thumbprint "a9 09 50 2d d8 2a e4 14 33 e6 f8 38 86 b0 0d 42 77 a3 2a 7b" should be specified as "a909502dd82ae41433e6f83886b00d4277a32a7b" in code. A fingerprint can, for example, be stored in an identification system database, a passport chip, or an access cards memory. It is suited for applications where a key, access card, or password is normally used. The fingerprint is then transformed into a numerical model which stores the fingerprints unique characteristics, such as the arches and loops and their distance from each other, as a series of numbers. It has two distinct and separate shoulders for each core, two deltas and one or more ridges that make a complete circuit. However, they can be very impulsive at times.
