  • Method of constructing credit cards for automatic vending equipment and credit purchase systems
    Patent number: 4020536
    Abstract: A special method of credit card construction is provided with the credit card precoded in binary code representing several digits and with a locator indicator to insure that the card is correctly positioned when inserted in the console or read-out station. The card coding includes the method of arranging high dielectric constant spots or discs and low dielectric constant spots or discs arranged in several bit groupings related to a plurality of identification digits. In one embodiment of the cards, which are preferably of the plastic material type, opaque conductive plastic inserts may additionally be included over and above the first mentioned discs so that the discs, their location and code arrangement cannot be readily ascertained.
    Type: Grant
    Filed: January 8, 1975
    Date of Patent: May 3, 1977
    Inventors: William E. Cuttill, Vilma M. Wagner
  • Credit card construction for automatic vending equipment and credit purchase systems
    Patent number: 4017834
    Abstract: A special credit card arrangement and construction is employed with the credit card precoded in binary code representing several digits and with a locator indicator to insure that the card is correctly positioned when inserted in the console or readout station. The card coding includes an arrangement of high dielectric constant spots or discs and low dielectric constant spots or discs arranged in several bit groupings related to a plurality of identification digits. In one embodiment of the cards, which are preferably of the plastic material type, opaque conductive plastic inserts may additionally be included over and above the first mentioned discs so that the discs, their location and code arrangement cannot be readily ascertained.

  • Automatic vending equipment and credit purchase systems
    Patent number: 3995255
    Abstract: The credit card is precoded in binary code representing several digits and has a locator indicator to insure that the card is correctly positioned when inserted in the console or read-out station. The card coding includes the method of arranging high dielectric constant spots or discs and low dielectric constant spots or discs in several groupings related to a plurality of identification digits. The circuitry for reading the encoded data on the credit card includes a capacitive voltage divider to reduce the effect of parasitic capacitance. Additionally, a relatively high voltage level sensing circuit is used to reduce the possibility of error due to oxide film, dirt, high resistance film or the like on the encoded spots.
