The values of loop counts are represented by small (S), medium (M), or large (L). To evaluate the value of major classification, ridge counting and ridge tracing are performed for loops and whorls, respectively. Values of Major Division Classification System Small Letter Grouping: In case, small letter grouping is present with secondary division values, both sub secondary, and major division are omitted. Arches: When plain and tented arches are on thumb fingers, major classification is not used.Ģ. For whorl patterns, ridge tracing is considered.ġ.If the pattern is a loop, ridge counting is obtained.Values: Ridge tracing and Ridge counting.Position: placed immediately to the left of the primary classification column.Numerator: Right thumb value (finger 1).Related Questions Rules for Major Classification System.Practical Worksheet for Finding Major Division Number.Major Classification for Scarred and Amputated Fingers.Procedure For Major Division Classification.Values of Major Division Classification System.Please feel free to share your opinion in the comment box. So, these are the many different types of fingerprints and some brief discussions about them. The plain arch is not included in this pattern because it lacks distinctive characteristics. Accidental: In short, any pattern that does not match with any of the previous fingerprint types.Īccidental type fingerprint patterns possess at least two characteristics of the tented arch, whorl or loop families combined.Double Loop Whorl: Double loop whorl appears to be two distinct loops that surround each other in opposing directions.Others: Other major types of fingerprint are:.In this pattern, ridges form a loop pattern that re-curves and surrounds a central whorl. Central Pocket Loop: Central pocket loop is defined as a composite fingerprint.But, a radial loop turns toward the thumb. Radial Loop: As like ulnar loop, radial loops are also created by its existence on the hand.These are categorized by the way they turn when looking at the fingerprint on the hand, not a fingerprinting card. Mostly, an ulnar loop moves toward the little finger. Ulnar Loop: Ulnar loop are created when fingerprint ridges turn backward but do not twist completely around.Arch: Arch is divided into two categories, Plain Arch and Tented Arch.Within these three categories of fingerprints, there are more sub categories of these patterns of fingerprints. Loops pattern must have one delta and one core. These are the most common fingerprint pattern. Loop: 60-70% of fingerprints patterns are loops.Any fingerprint pattern that contains equal or more than 2 deltas will be a whorl pattern. Whorls have at least two deltas and a core. Whorl: 25-35% of fingerprint patterns are whorls.An arch doesn’t have any delta, lines, or cores. Arch: Only a few, that is close to 5% have this type of fingerprint.Here we will try to discuss about these different types of fingerprints. Many people have asked about the types of fingerprints and what they mean. More specifically there are three types of fingerprints. But, there are different types of fingerprints. Types of Fingerprints SourceĮveryone’s fingerprint is unique, even for identical twins. It is a widely accepted biometric method that is used in various industries including law enforcement agencies, schools, hospitals, banks, private organizations etc. Fingerprint recognition is one of the most popular biometric modalities across the world. Biometric technology is a method of verifying humans based on physical or behavioral biometric data.
