found at 63.9%. Arch pattern was found on the
right index (12.5%), the left index and middle
fingers (11.1%), radial loop pattern appeared only
on the index fingers (8.3% on the left index; 5.6%
on the right index) as shown in Table 1. Diversity
of types of fingerprint patterns of ten-finger was
found mostly in two types of patterns i.e. whorl
plus ulnar loop (41 subjects or 56.9%) as shown in
Fig. 1.
Figure 1. Image of ten-fingerprint obtained from the Automated Inkless Fingerprint Imaging Software.
There are 8 ulnar loops [left thumb (L1), middle (L3), ring (L4), little (L5), and the right thumb
(R1), index (R2), Middle (R3), and little fingers (R5)] and 2 whorls on the left index (L2) and
right ring fingers (R4).
