Other Fingerprint Systems (Manual Methods or Systems)
- 1. The single finger system, which is also known as the Battley system, was developed by Chief Inspector Henry Battley of the New York State fingerprint bureau.
- 2. The single hand system was patterned after a system developed by Anita Field of the Los Angeles Police department.
- 3. San Francisco Police Department Five Finger system.
It should also be noted that a variety of other systems have been developed and implemented throughout the world. However, with the advent of AFIS or IAFIS, many of the manual systems that have been developed are no longer being used.
The Automated Fingerprint Identification System (AFIS) is a computerized designation of fingerprint patterns for searching within the database. Designation using this system is the least complicated method. This method is based on pattern recognition. There are five possible designations that may be used for classification purposes: A, W, R, L, S.
- • A = Arch or tented arch patterns
- • W = Any type of whorl (plain, double loop, central pocket, accidental)
- • R = Right slanted loop (for purposes of AFIS, it does not matter if the loop is an ulnar or radial loop, only that the flow is to the right).
- • L = Left slanted loop (for purposes of AFIS, it do not matter if the loop is an ulnar or radial loop, only that the flow is to the left). As a reminder, to determine the line of flow, begin at the core and follow the ridges away from the core to determine the flow of the pattern.
- • S = Scar (this designation is where a pattern cannot be determined or the damage to the pattern is severe).
- • X = Amputated or missing finger.
