Telephone card or the like using lenticular lens material |
摘要 |
A card (10) for use as a telephone authorization card or the like is comprised of a layer of a backing material (20) such as a stiff plastic material which has some pliability. A thin sheet lenticular lens material (12) has a flat surface (14) on which is printed selected interlaced images. On the other side of the lens material is formed a plurality of lenticules (16) through which the images are viewed. The flat side of the lenticular material is secured to one face (22) of the backing in a convenient manner. A cutting tool is now used to form an opening (32) in the outer face of the lenticules and a programmed microchip (30) is inserted in the opening and secured in place. On the outer face of the backing material a magnetic strip (40) containing magnetically encoded indicia is secured. The card is usable in a reader (R) which can scan the magnetic strip and read information from the microchip to allow the user to place a telephone call or conduct other transactions.
