The primary classification system is a 10-finger system. Therefore it must be used when prints from both hands are available. Using this method, all of the fingerprints in the world could be divided into 1,024 groups. Fingers on each hand are given an identifying number.

What are the patterns used to obtain primary classification?

PRIMARY – The primary classification is obtained through the summation of the value of the whorl type patterns as they appear in the various fingers: Even numbered fingers (2, 4, 6, 8 and 10), being used as the numerator and odd numbered fingers (1, 3, 5, 7 and 9), as the denominator.
