摘要：

Methods of creating tamper resistant informational articles and related products are disclosed. In one method a metal foil has a hologram formed therein after which information is created on the metal foil at least partially over the hologram and the foil is encapsulated in a resinous plastic material. Encapsulation may be effected by extruding the resinous plastic material. The assembly may be separated into individual informational articles which resist tampering and resist undesired counterfeiting as by photocopying. In another embodiment, a tamper resistant informational article is provided by creating a base having an upper surface and a lower surface with an elongated metal core having extruded therearound a resinous plastic material. A magnetic media storage element is secured to this base. 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 lower surface is then secured to the base upper surface to protectively surround the information. This joinder of the base and lens is preferably accomplished when the extruded resinous plastic material is at an elevated temperature. Particles which resist photocopying may be incorporated in the resinous plastic material prior to extrusion. The magnetic storage element may be an elongated magnetic strip or a microchip, for example. An antenna operatively associated with the magnetic strip or microchip may be provided. Products produced by these methods are also disclosed. In one embodiment, the metal core serves as a ground to resist undesired loss of information stored on the magnetic media. 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.
