ABSTRACT:
A system and method for taking and developing a fingerprint wherein the subject's fingers are not dirtied or exposed to chemicals. The fingerprint is recorded on a layer of adhesive adhered to a sheet of transparent material. The print is developed by making a copy of it on a sensitized surface by back reflecting radiant energy through the adhesive whereby the print is imaged.
