Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
117 words
A tamper-proof and wear-resistant identification card comprising: a support member having a front surface and a rear surface; a recording means on one of said surfaces for storing encoded data; a first transparent layer overlying said front surface of said support member and having a first surface; a transparent bond layer attaching said first surface to said front surface of said support member; a second transparent layer overlying said rear surface of said support member and said recording means; a second transparent bond layer bonding said second transparent layer to said rear surface of said support member; and an invisible optically-readable code imprinted at the bond layer between one of said transparent layers and said support member.
Claim 2
Dependent Claim
117 words
A tamper-proof and wear-resistant identification card comprising: a support member having a front surface and a rear surface; a recording means on one of said surfaces for storing encoded data; a first transparent layer overlying said front surface of said support member and having a first surface; a transparent bond layer attaching said first surface to said front surface of said support member; a second transparent layer overlying said rear surface of said support member and said recording means; a second transparent bond layer bonding said second transparent layer to said rear surface of said support member; and an invisible optically-readable code imprinted at the bond layer between one of said transparent layers and said support member.
Claim 3
Dependent Claim
22 words
The identification card of claim 1 wherein said optically-readable code includes coded alphanumeric characters corresponding to data encoded on said recording means.
Claim 4
Dependent Claim
34 words
The identification card of claims 1 or 2 further comprising said code being imprinted in ink dispersed in one of said bond layers upon bonding of said one transparent layer to said support member.
Claim 5
Dependent Claim
104 words
In an identification card having a thin flexible self-sustaining support member having front and back surfaces, a magnetic recording stripe fixed to said back surface a code area on said support member bearing embossed indicia, a recessed area receiving a visually inspectable identification such as a photograph, a transparent cover and a transparent bond layer attaching said cover to one of said surfaces; the improvement comprising an invisible verification code located at said bond layer between said cover and said one surface, said verification code being detectable upon exposure to radiant energy of a predetermined wavelength and being destructable if the bond is disturbed.
Claim 6
Dependent Claim
104 words
In an identification card having a thin flexible self-sustaining support member having front and back surfaces, a magnetic recording stripe fixed to said back surface a code area on said support member bearing embossed indicia, a recessed area receiving a visually inspectable identification such as a photograph, a transparent cover and a transparent bond layer attaching said cover to one of said surfaces; the improvement comprising an invisible verification code located at said bond layer between said cover and said one surface, said verification code being detectable upon exposure to radiant energy of a predetermined wavelength and being destructable if the bond is disturbed.
Claim 7
Dependent Claim
27 words
An identification card as defined in claim 2 or 4, wherein said code is imprinted by a material detectable only under light conditions outside the visible spectrum.
Claim 8
Dependent Claim
22 words
An identification card as defined in claims 1 or 2 wherein said recording means includes a layer of high coercivity magnetic tape.
