Abstract
Abstract An identification device is provided which includes a substrate having a portion of one surface constructed so as to be absorbent and capable of permanently accepting an invisible indicia such as a signature. The said portion of said substrate is of selfdestructing safety printing so that tampering therewith is readily ascertainable and will obscure a slight visible cast resulting from transferring invisible indicia thereto. The substrate is preferably comprised of a paper layer on opposite sides of a tough polymeric plastic such as Mylar bonded thereto. The identification device is preferably in the form of an identification or credit card bearing a signature, which signature may only be seen when subjected to radiant energy such as ultra violet light.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
101 words
An identification device comprising first and second paper substrates and a third substrate comprised of polymeric material, said third substrate being interposed between said first and second substrates in facing relation thereto, one of said paper substrates having indicia on a surface remote from said third substrate, a portion of said surface being absorbent to permanently accept indicia which is invisible when viewed in the visible spectrum, said portion being comprised of selfdestructing safety printing so that tampering therewith is readily ascertainable, and said surfaces of said first and second substrates are bonded to said facing surfaces of said third substrate.
Claim 2
Dependent Claim
101 words
An identification device comprising first and second paper substrates and a third substrate comprised of polymeric material, said third substrate being interposed between said first and second substrates in facing relation thereto, one of said paper substrates having indicia on a surface remote from said third substrate, a portion of said surface being absorbent to permanently accept indicia which is invisible when viewed in the visible spectrum, said portion being comprised of selfdestructing safety printing so that tampering therewith is readily ascertainable, and said surfaces of said first and second substrates are bonded to said facing surfaces of said third substrate.
Claim 3
Dependent Claim
40 words
A device in accordance with claim 1 wherein said portion has a signature thereon which is invisible in the visible spectrum, and a fourth substrate of transparent polymeric material joined to said surface carrying said portion in overlying relation thereto.
Claim 4
Dependent Claim
20 words
A device in accordance with claim 1 wherein said layer has an approximate thickness of between 0.004 and 0.014 inch.
Claim 5
Dependent Claim
21 words
A device in accordance with claim 1 wherein said substrate is paper having a thickness of approximately 0.002 and 0.003 inch.
Claim 6
Dependent Claim
23 words
A device in accordance with claim 1 wherein said portion contains a signature which is invisible except when viewed under ultra violet light.
Claim 7
Dependent Claim
22 words
A device in accordance with claim 1 including a second layer of polymeric plastic material overlying and bonded to said second substrate.
Claim 8
Dependent Claim
21 words
A device in accordance with claim 6 wherein said second layer of plastic material has embossed indicia thereon for credit purposes.
Claim 9
Dependent Claim
36 words
A device in accordance with claim 1 wherein said portion has a signature thereon which is invisible in the visible spectrum, and a layer of transparent polymeric material joined to said one surface overlying said portion.
Claim 10
Dependent Claim
107 words
An identification device comprising a generally rectangular paper substrate having a thickness of about 0.002 and 0.003 inch, a portion of said surface being absorbent and capable of permanently accepting an invisible indicia such as a signature, said portion being of self-destructing safety printing so that tampering therewith is readily ascertainable and for obscuring a slight visible cast resulting from transferring invisible indicia thereto, a film of Mylar bonded to a surface of said substrate opposite to said first-mentioned surface so that no depression is left on said substrate by the transfer of said iNvisible indicia thereto, said Mylar film having a thickness of approximately 0.005 inches.
Claim 11
Dependent Claim
