Analysts in the Friction Ridge Section examine fingerprints "after the fact." Each finger and
thumb is unique to an individual and no two prints have ever been found to be exactly the same from two
different people. Also, palm and footprints are also unique to each individual. There are approximately
75 to 200 characteristics on a finger or thumb. The analysts use a variety of techniques --such as carbon
powder dusting, super-glue and ninhydrin spray techniques, amido-black print visualization, and argon
laser identification --to identify and match prints. The DPS Crime Labs that currently provide
Friction Ridge Processing and/or Comparison include: Austin, Weslaco, Garland, and Corpus Christi.
The friction AFIS operations augment the capabilities of the Friction Ridge Section.
