Today, one of the greatest usages of fingerprinting is in the identification of children. Mayer was the first to declare that friction ridge skin is unique. The results of these experiments demonstrate that people can identify fingerprints quite well, and that matching accuracy can vary as a function of both source finger type and image similarity.Nonprofit site dedicated to fingerprints, finger prints, fingerprint, finger print, Latent Print Examination, Fingerprint FAQs, AFIS - automated fingerprint identification systems, fingerprint training, superglue (super glue - cyanoacrylate) development of latent prints, fingerprint and latent print employment jobs listed, Scientific Working Group on Friction Ridge Analysis, Study and.
