Abstract
Abstract A quick and clean method of recording fingerprints without inks, chemicals, or powders is disclosed. The invention is especially suited for incorporation into mass produced legal and financial documents, wherein a portion of a document is fabricated to include a protected area for the recording and preservation of a latent fingerprint. The fingerprint receptive area of the document is protected by a cover which removably adheres to the document. If the identity by a cover which removably adheres to the documents. If the identity of a party signing the document is later questioned, the cover may be removed from the pad to expose the fingerprint for forensic processing or AFIS scanning

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
47 words
A latent fingerprint recording device, comprising; a sheet of material possessing a reflective surface of sufficient size to record at least one fingerprint image over said reflective surface; and a protective cover mounted above said reflective surface to protect the surface from contamination or adulteration during storage.
Claim 2
Dependent Claim
47 words
A latent fingerprint recording device, comprising; a sheet of material possessing a reflective surface of sufficient size to record at least one fingerprint image over said reflective surface; and a protective cover mounted above said reflective surface to protect the surface from contamination or adulteration during storage.
Claim 3
Dependent Claim
27 words
The fingerprint recording device of claim 1, further including a fingerprint sensitive material applied to said reflective surface to receive an imprint of the latent fingerprint images.
Claim 4
Dependent Claim
44 words
The fingerprint recording device of claim 2, wherein said fingerprint sensitive imprinting material is a material which is impregnated with chemical reagents which react to the materials contained in a naturally occurring latent fingerprint to produce a more visible image of the fingerprint image.
Claim 5
Dependent Claim
25 words
The fingerprint recording device of claim 1, further including a hinge means for preventing said protective cover from accidentally separating from said sheet of material.
Claim 6
Dependent Claim
31 words
The fingerprint recording device of claim 1, wherein said protective cover includes a tab means integral with said protective cover by which the cover may be more easily grasped and lifted.
Claim 7
Dependent Claim
33 words
The fingerprint recording device of claim 1, wherein said protective cover consists of a transparent, light polarizing material to increase the contrast and visibility of the fingerprint image when viewed through the cover.
Claim 8
Dependent Claim
103 words
A latent fingerprint recording device, comprising; a document having a reserved area of sufficient size to record a naturally occurring fingerprint image over said document's surface; a layer of image enhancing material which is printed, painted, screened, stamped, or impregnated into said reserved area of said document; and a protective cover hingedly mounted along an edge of said reserved area of said document to protect said image enhancing material from degradation or adulteration during storage, whereby said protective cover may be repeatedly lifted or replaced over said reserved area to allow for recording the fingerprint image and unobstructed processing of the fingerprint image.
Claim 9
Dependent Claim
103 words
A latent fingerprint recording device, comprising; a document having a reserved area of sufficient size to record a naturally occurring fingerprint image over said document's surface; a layer of image enhancing material which is printed, painted, screened, stamped, or impregnated into said reserved area of said document; and a protective cover hingedly mounted along an edge of said reserved area of said document to protect said image enhancing material from degradation or adulteration during storage, whereby said protective cover may be repeatedly lifted or replaced over said reserved area to allow for recording the fingerprint image and unobstructed processing of the fingerprint image.
Claim 10
Dependent Claim
35 words
The fingerprint recording device of claim 7, further including a layer of adhesive-like material applied between said document and said protective cover whereby said protective cover is prevented from accidentally lifting off of said document.
