Abstract
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.
