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 (192) with an elongated metal core (206) having extruded therearound a resinous plastic material (210). A magnetic media storage element (212) is secured to this base. An antenna (220) may be provided. In another embodiment, a lens is created by providing an elongated transparent layer, forming a hologram (200) in the lower surface thereof and applying information to the hologram. The lens (190) 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. Printing may be provided on the hologram before metallizing. A base portion protectively underlies the modified metallized layer.
