Abstract
Abstract An identity check card including an identified fingerprint of the legitimate card holder, said fingerprint being cut away to provide alternate transparent zones and partial fingerprint zones. The placement of the card over a fresh fingerprint of the same identified finger of the person whose identity is being checked will show immediately if the latter complements the former in its transparent zones thus permitting a quick and reliable check to be effected.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
38 words
Identity Checking Device comprising a card having a region carrying an identified fingerprint of a given finger of the legitimate card holder, said fingerprint having sections cut therefrom whereby said region comprises alternate transparent and partial fingerprint zones.
Claim 2
Dependent Claim
38 words
Identity Checking Device comprising a card having a region carrying an identified fingerprint of a given finger of the legitimate card holder, said fingerprint having sections cut therefrom whereby said region comprises alternate transparent and partial fingerprint zones.
Claim 3
Dependent Claim
30 words
Identity Checking Device according to claim 1 in which at least the majority of said transparent zones are radially arranged with respect to a first reference point of said fingerprint.
Claim 4
Dependent Claim
44 words
Identity Checking Device according to claim 2 in which said transparent zones are centered on but, except for one, do not reach said first reference point which is the center of a relatively small circular fingerprint zone, cut only by said one transparent zone.
Claim 5
Dependent Claim
21 words
Identity Checking Device according to claim 3 in which said transparent zones are larger angle sectors than said partial fingerprint zones.
Claim 6
Dependent Claim
32 words
Identity Checking Device according to claim 4 in which the majority of transparent zones comprise fourteen approximately 15° sectors separated, except for one pair thereof, by thirteen approximately 9° partial fingerprint sectors.
Claim 7
Dependent Claim
50 words
Identity Checking Device according to claim 5 in which there is a fourteenth partial fingerprint sector having an angle of approximately 33°, said fourteenth sector containing a second reference point of said fingerprint and a sector thereof removed, centered on said second reference point, to define an additional transparent zone.
Claim 8
Dependent Claim
24 words
Identity Checking Device according to claim 6 in which said additional transparent zone defines an angle of approximately 15° at said second reference point.
Claim 9
Dependent Claim
53 words
Identity Checking Device according to claim 6 in which, depending on the type of fingerprint, said first reference point is a point chosen from (a) the center of the loop and (b) the center of the whorl, and further in which said second reference point is the center of the delta (Vucetich system).
Claim 10
Dependent Claim
39 words
Identity Checking Device according to claim 2 in which, depending on the type of fingerprint, said first reference point is a point chosen from (a) the center of the loop and (b) the center of the whorl (Vucetich system).
Claim 11
Dependent Claim
38 words
Identity Checking Device according to claim 9 in which said card has a second region carrying a second but complete fingerprint of said given finger next to said first mentioned partially transparent fingerprint, to assist checking during use.
Claim 12
Dependent Claim
19 words
Identity Checking Device according to claim 10 in which said second fingerprint has said first reference point marked thereon.
Claim 13
Dependent Claim
27 words
