| 61 | Credit card and method of making the same | US79921 | 1987-07-31 | US4897533A | 1990-01-30 | John L. Lyszczarz |
| An improved credit card having a clear, unbroken metallized surface with printed graphics thereon which is scratch resistant and a method of making the same are disclosed. The method involves heat transferring a metallized foil to a first surface of a plastic substrate, silk-screen printing over the metallized foil with ultraviolet curable ink, drying the ink with ultraviolet light and overlaminating the printed foil with a clear polyester film coated with a heat-activated adhesive or coating it with an ultraviolet curable varnish which is cured by applying ultraviolet light to the coating. The plastic substrate is in the form of a large sheet from which a plurality of cards are die cut after the printing and application of the transparent film. A magnetic tape is then applied to the back of each card. | ||||||

| 63 | Personal information card system | US822067 | 1986-01-24 | US4745268A | 1988-05-17 | Jerome Drexler |
| A system in which wallet-sized visually readable information relating to a person is created on material disposed on one side of a wallet-size card and machine readable information relating to the person is recorded on a laser recordable optical data storage strip disposed on the opposite side of the card. The visually readable information may be a fingerprint or face photograph created by conventional photography or with a laser. The data storage strip is disposed in the card and may be a pre-formed strip of laser recording material. Information spots recorded on the strip may be insurance, medical, banking, security or other transaction information. Both the machine readable information and the eye readable information are read simultaneously by two optical systems, one disposed on each side of the card. | ||||||
| 64 | Sheet containing contour-dependent directional image and method for forming the same | US944458 | 1986-12-19 | US4714656A | 1987-12-22 | Thomas I. Bradshaw; Bruce D. Orensteen; Jack E. Cook |

| 65 | Identification article with pattern-form fresnel hologram, fabrication thereof, and verification thereof | US830491 | 1986-02-19 | US4677285A | 1987-06-30 | Yukio Taniguchi |
| An identification article comprise a substrate and a pattern-form Fresnel hologram provided as an identification information providing layer on the surface or in the interior of the substrate structure. The pattern-form Fresnel hologram is formed by (a) forming a Fresnel hologram by exposing a photosensitive resin layer to an interference light obtained from interference between an object light beam and a reference light beam both obtained by dividing a single coherent light, (b) exposing the Fresnel hologram to light transmitted through a mask pattern, (c) fabricating a pattern-form Fresnel hologram by developing the Fresnel hologram, and (d) reconstructing the pattern-form Fresnel hologram thus obtained. The identification article is verified by projecting a monochromatic light onto the hologram to reproduce an image and projecting this image on a screen or detecting it with a light detector. | ||||||
| 66 | Optically diffracting security element | US681555 | 1984-12-14 | US4662653A | 1987-05-05 | David L. Greenaway |
| A security element for authenticating bank notes, credit cards, security passes and the like is disclosed. The security element incorporates a reflective-type diffraction grating, which grating comprises a continuous layer of reflecting material on which is deposited a layer of dielectric material. Non-continuous reflecting layer portions are embedded in the dielectric material. It is practically impossible to lay bare the diffraction grating without destroying it. | ||||||
| 67 | Identification system comprising a partially reflective retardation device | US677427 | 1984-12-03 | US4659112A | 1987-04-21 | Daniel T. Reiner; Lawrence Bolt; Philip W. Morlan, Jr.; Ali Tavasolian |
| There is disclosed a tamper-free identification system, such as an ID card, comprising an information-bearing substrate made of a flexible but substantially rigid material, a partial light reflector superposed over said substrate which produces a substantially nondepolarizing light reflection, and a substantially transparent 90.degree. retarder superposed over said reflector. Said identification card can be manufactured at low cost using techniques known in the art, and with the aid of a simple and inexpensive analyzer such as a linear light polarizer, fraudulent alternations of the identification card can readily be detected. | ||||||
| 68 | Security filament for use in identification cards | US578650 | 1984-02-09 | US4618167A | 1986-10-21 | Edwin N. Whitehead |
| A filament for use with identification cards to render them tamper and fraud resistant having a meltable core of twisted polymeric micro-filaments which is wrapped with metal foil in a manner to leave portions of the core exposed. | ||||||
| 69 | Secure badge for infrared badge reader and process for making same | US608144 | 1984-05-08 | US4583766A | 1986-04-22 | Kenneth R. Wessel |
| An improved security badge is provided for use with an infrared badge reader. The badge is formed from a plurality of layers of PVC film which are laminated under appropriate conditions of heat and pressure to form an integral member. An infrared blocking material is disposed intermediate two of the layers. The non-blocking portions of the badge transmit between 0.90% and 1.25% infrared light. | ||||||
| 70 | Token such as credit or identification card and an apparatus for testing the token or card | US413650 | 1982-09-01 | US4527051A | 1985-07-02 | Gerhard Stenzel |
| A security document such as a credit card or the like has material adapted to be optically scanned arranged along a line in the document. A modulating structure such as a document paper thickness is disposed within the document so as to be positioned between the line and an optically scanning, light sensing device. Accordingly, light emitting material in the line of the card upon being scanned will have the light thereof modulated so as to produce a reproducible authenticating variable when said line is scanned by the light sensing device. | ||||||
| 71 | Multilayer identification card and a method of producing it | US478714 | 1983-03-25 | US4507346A | 1985-03-26 | Thomas Maurer; Hans-Jurgen Holbein; Joseph S. Lass |
| A multilayer identification card bearing information such as letters, numbers, patterns, pictures and so on, in which at least part of the information is present in the form of a structure in relief in a foamable synthetic material. The foamable synthetic material is transparent or dyed in the visible spectral range and is present in the identification card in the form of a layer covering either its entire surface or part of it. The information in relief is produced by means of a laser beam recorder, the energy dosage of which is used to induce the locally controllable foaming process in the synthetic material compounded with chemical or physical blowing agents. The protection against forgery may be further increased by additionally photocuring the foamable synthetic layer. | ||||||
