Abstract

A fingerprint sensitive pad is disclosed for affixing a fingerprint to a document. The pad includes a base sheet adhesively attached to the document. The base sheet, which may be reflective, has an adhesive-like coating which receives the fingerprint image when a finger is pressed upon it. The pad has a hinged cover, which removably adheres to the adhesive-like coating to protect the fingerprint image.

Claims

1. A fingerprint sensitive pad for imprinting and storing a fingerprint image on a document, comprising:

a substrate sheet having a reflective surface and an opposing surface;

a layer of inkless imprinting material applied to said reflective surface of the substrate sheet to receive an imprint of a finger;

a flexible protective cover hingedly mounted along an edge of said substrate sheet to protect a latent fingerprint image from degradation and adulteration during storage; and

a layer of adhesive backing on said opposing surface of the substrate sheet to secure the fingerprint sensitive pad to a document, wherein the document in association with said fingerprint sensitive pad provides an identification records system for positively identifying a person involved in a transaction.

2. The fingerprint sensitive pad according to claim 1 wherein said flexible protective cover comprises of opaque material to protect the latent fingerprint image from photodegradation and to preserve confidentiality of the person involved in the transaction.

3. The fingerprint sensitive pad according to claim 1 wherein said flexible protective cover comprises a transparent material.

4. The fingerprint sensitive pad according to claim 1 wherein said layer of inkless imprinting material consists of a thin coating of a transparent tacky substance.

5. The fingerprint sensitive pad according to claim 1 wherein said substrate sheet having a reflective surface consists of a sheet of polished metallic material having a mirrorlike surface.
