Dermatoglyphic Identification
this form of indentifying individuals was developed by Jaso Corporation, and is often regarded as the finest physical identification system in the galaxy. Although not as precise as retinal scanning, it uses a database which is much more readily available to other systems. Dermatoglyphic identification takes a skin sample from the subject's thumb or fingers, and a number of tests and analyses are performed on the sample. Cytoplasmic biopsies and chitinous accretion analysis are the most useful tests for those species which do not have dermatoglyphic patterns. This form of identification cannot distinguish between clones or other beings with identical genetic material, and scar tissue or artificial skin grafts produce no results at all. One species which was abused by dermatoglyphic identification was the Wookiee race, because their hands and feet were often scarred during attempts to escape capture by Imperial slavers. Thus, the Imperials took skin samples from the sensitive skin on the Wookiees' nose.
