MAGNETIC CARDS

摘要

Magnetic cards are formed by plural, coadjoining, generally planar, parallel layers. Outermost layers form outer sides of each card. At least a first visible image is provided on a first of the outer sides. The card includes a generally planar, permanently magnetized layer formed by one or more permanently magnetizable planar components that are fixedly positioned preferably within a frame between the opaque outer sides or a magnetizable material layer only part of which has been selectively permanently magnetized. The permanently magnetized layer or permanently magnetized portion of a larger, magnetizable layer has a predetermined configuration which is related at least in informational content to the first visible image. A silhouette of the predetermined configuration can be magnetically reproduced by placing a card on a magnetically actuated fluid display panel. The permanently magnetized component(s) or magnetized portion(s) of the permanently magnetizable layer generates an image on the panel which has a silhouette identical in configuration to that of the permanently magnetized component(s) or portion(s). Two magnetic layers and two images on opposite outer sides of each card can be provided as well as visible images formed by depressions into the outer surface or cut-outs completely through a card.
