Abstract

Methods of creating tamper resistant informational articles and related products are disclosed. In one embodiment, a tamper resistant informational article is provided by creating a base with an elongated metal core having extruded therearound a resinous plastic material. A magnetic media storage element is secured to this base. An antenna may be provided. In another embodiment, a lens is created by providing an elongated transparent layer, forming a hologram in the lower surface thereof and applying information to the hologram. The lens is then secured to a base to protectively surround the information. In another embodiment, a preformed transparent hologram-containing article has information added thereto and is then metallized. A protective resinous layer may be secured over the metallized layer. In another variation of the embodiment, a lens has a preformed transparent hologram, one or more metallized portions are provided and may be altered through selective application of heat to predetermined parts thereof to create information which may be fixed or variable. Printing may be provided on the hologram before metallizing. A base portion protectively underlies the modified metallized layer.

Claims

1. A method of creating a tamper resistant informational article comprising

creating a resinous base having an upper surface and a lower surface,

creating a lens by providing an elongated transparent resinous layer and forming a hologram in the lower surface thereof,

metallizing at least a portion of said hologram,

establishing information on said lens by applying heat to predetermined parts of said metallized portions, and

permanently securing the upper surface of said base to the lower surface of said lens.

2. The method of claim 1 including

applying said heat to predetermined portions of said metallized portions to effect permanent modification thereof.

3. The method of claim 2 including

effecting said modification of said metallized portions by heating said portions electrically.

4. The method of claim 3 including

employing a thermal printer to effect said heating in predetermined parts of said metallized portions.

5. The method of claim 2 including

effecting by said application of said heat permanent modification of a portion of said lens.

6. The method of claim 2 including

creating said metallized portions as a coating.

7. The method of claim 6 including

creating said metallized portions coating in a thickness of about 80 to 120 Angstroms.

8. The method of claim 1 including

after effecting said metallizing, but before effecting heating of said metal portions storing said lens.

9. The method of claim 8 including

effecting said heating of said metallized portions to create at least one of fixed information and variable information.

10. The method of claim 1 including

employing a said base which is generally opaque.

11. The method of claim 10 including

effecting said base and lens securement at an elevated temperature.

12. The method of claim 11 including

subsequent to said securing of said base to said lens cooling said lens-base assembly.

13. The method of claim 1 including

creating said lens in an elongated strip which is subsequently severed into individual lenses.

14. The method of claim 13 including

creating said bases in an elongated strip which is subsequently severed into individual bases.

15. The method of claim 1 including

creating said lens in an elongated strip,

creating said bases in an elongated strip,

after said heating of said predetermined parts of said metallized portions securing said elongated lens to said elongated base, and

subsequently severing said elongated lens base assembly into individual informational articles.

16. The method of claim 1 including

forming said lens base assembly in multiple widths, and

subsequently severing individual informational articles therefrom.

17. The method of claim 1 including

printing information on said hologram prior to said metallizing.

18. The method of claim 17 including

creating a plurality of said metallized portions.

19. The method of claim 1 including

prior to creating said hologram incorporating a plurality of particles of a different material within said resinous layer material.

20. The method of claim 19 including

incorporating glass beads as said particles.

21. The method of claim 1 including

securing an anti-abrasion material to the upper surface of said lens.

22. The method of claim 1 including

prior to effecting said metallizing creating information on said lens on or adjacent said hologram by a thermal transfer printer.

23. The method of claim 22 including

establishing a plurality of said metallized portions, and

creating said information on a plurality of said metallized portions.

24. The method of claim 1 including

securing a magnetic media storage element.

25. The method of claim 24 including

effecting said metallizing at least partially over said first information.

26. The method of claim 1 including

effecting said metallizing without applying any information on said hologram prior to said metallizing.

27. The method of claim 1 including

creating said hologram containing lens at a first manufacturing location, and

completing manufacture of said informational article at a second manufacturing location.

28. A tamper resistant informational article comprising

a transparent resinous lens having an upper surface and a lower surface,

a hologram formed in the lower surface thereof,

at least one metallized portion underlying and covering at least a portion of said hologram,

thermally formed alterations in said metallized portions to create information visible through said lens,

a base composed of a resinous plastic material, and

the upper surface of said base being permanently secured to the lower surface of said lens, whereby said hologram and information will be protectively encased within said article.

29. The tamper resistant informational article of claim 28 including

a plurality of particles of a different material disposed within said lens.

30. The tamper resistant informational article of claim 29 including

said particles being glass beads.

31. The tamper resistant informational article of claim 28 including

said article having a plurality of said metallized portions.

32. The tamper resistant informational article of claim 28 including

an anti-abrasion material secured to the upper surface of said lens.

33. The tamper resistant informational article of claim 28 including

said informational article being a card, and

said card being selected from the group consisting of credit cards, debit cards smart cards, identification cards, organization membership cards and security cards.

34. The informational article of claim 28 including

said base being generally opaque.

35. The informational article of claim 28 including

said thermally formed alterations in said metallized portions being visible through the upper portion of said lens.

36. The informational article of claim 28 including

said information being fixed information, variable information or a combination of both.

37. The informational article of claim 28 including

thermally formed alterations in said transparent resinous lens corresponding to said thermally formed alterations in said metallized portions.

38. The informational article of claim 28 including
