Abstract
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.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
58 words
A fingerprinting system comprising a sheet of transparent material coated with a film of adhesive sensitive to record a fingerprint, a means for back reflecting radiant energy and a means for making a copy of the fingerprint on a sensitized surface, said means for back reflecting radiant energy reflecting said energy to said means for making a copy.
Claim 2
Dependent Claim
58 words
A fingerprinting system comprising a sheet of transparent material coated with a film of adhesive sensitive to record a fingerprint, a means for back reflecting radiant energy and a means for making a copy of the fingerprint on a sensitized surface, said means for back reflecting radiant energy reflecting said energy to said means for making a copy.
Claim 3
Dependent Claim
17 words
The system of claim 1 wherein the means for back reflecting the radiant energy is a mirror.
Claim 4
Dependent Claim
19 words
The system of claim 1 wherein the means for back reflecting the radiant energy is a polished metal surface.
Claim 5
Dependent Claim
23 words
The system of claim 1 wherein the means for back reflecting the radiant energy is a polished dark surface which will copy black.
Claim 6
Dependent Claim
105 words
A fingerprinting system for a credit card invoice comprising an extension tab attached to the invoice and separable from the invoice by means of perforations, said extension tab having a window covered with a thin sheet of substantially transparent material, an adhesive sensitive to record a fingerprint adhesively engaged to the sheet, a means for back reflecting radiant energy through the adhesive and a means for making a copy of the fingerprint on a sensitized surface, said invoice and said extension tab having indicia for correlating them and said means for back reflecting radiant energy reflecting said energy to said means for making a copy.
Claim 7
Dependent Claim
105 words
A fingerprinting system for a credit card invoice comprising an extension tab attached to the invoice and separable from the invoice by means of perforations, said extension tab having a window covered with a thin sheet of substantially transparent material, an adhesive sensitive to record a fingerprint adhesively engaged to the sheet, a means for back reflecting radiant energy through the adhesive and a means for making a copy of the fingerprint on a sensitized surface, said invoice and said extension tab having indicia for correlating them and said means for back reflecting radiant energy reflecting said energy to said means for making a copy.
Claim 8
Dependent Claim
50 words
The system of claim 5 wherein the means for back reflecting the radiant energy is a member selected from the group consisting of a mirror, a polished metal surface and a polished dark surface which will copy black and wherein the means for making the copy is a photocopy machine.
Claim 9
Dependent Claim
26 words
The system of claim 6 wherein the sheet of substantially transparent material is made of polyethylene terephthalate and is from 1 mil to 10 mil thick.
Claim 10
Dependent Claim
20 words
The system of claim 7 wherein the sheet of substantially transparent material is from 4 mil to 5 mil thick.
Claim 11
Dependent Claim
17 words
