  • Patent number: 4004136
    Abstract: A credit verification terminal for use in several credit systems includes a dual purpose mechanism for sequentially propelling a user's credit card past a reading head, and for storing merchant identifying and other data that can be read by the head. In one embodiment, the mechanism comprises an axially movable drum containing coaxial bands of encoded data. As the drum is rotated, a selected band containing merchant data is read; further drum rotational propels a credit card past the head, so that the user data contained thereon is read. In another embodiment, a planar card carrier includes a movable table containing parallel stripes or rows of encoded merchant and other data on one surface thereof. The user's credit card placed on the carrier is propelled past the head in one direction, and the data recorded is read; with the card removed, the merchant data is read when the carrier is moved past the head to its initial position. Apparatus for changing the stored merchant information is described.

  • Patent number: 3959585
    Abstract: A graphical input terminal includes a pair of resistive sheets separated by an air gap. An energizing voltage is alternately applied to each sheet while an output voltage representative of the position of contact between the sheets caused by the pressure of a stylus, is derived from the nonenergized sheet. A circuit for indicating stylus up/stylus down status without undue interference from capacitively induced voltages is also provided.
