Abstract
A self contained three sheet fingerprint applicator and recording substrate utilizes a base sheet (10) adapted to be fixed to a suitable surface, such as a package, for receiving the fingerprint, an intermediate sheet (14) with a removable section containing an ink pad (14a) infused with an ink or inkless regent compatible with the development of a fingerprint when transferred to the base sheet (10) by a person's fingerprint area and a top sheet (16) with a removable section covering the ink pad.

A self-contained fingerprint ink/inkless reagent applicator and recording surface for recording a person's fingerprint comprising:
- a base sheet having a lower surface with an adhesive thereon adapted to be affixed to a suitable surface and an upper surface suitable for receiving a fingerprint;
- an intermediate sheet containing an ink/inkless reagent dispensing pad on an upper surface thereof and a bottom fluid impermeable layer disposed between the ink pad and the base sheet;
- and
- a top sheet having an upper surface and a lower surface disposed adjacent the upper surface of the ink pad with a fluid impermeable layer disposed between the ink reagent pad and the top sheet, at least a portion of the top and intermediate sheets being removable, the ink reagent pad containing a chemical compound which when applied to a person's fingerprint area and deposited onto the upper surface of the recording sheet will form a colored pattern representative of the ridges and ridge endings of the fingerprint area.
