Abstract A credit card utilization system. A plurality of credit cards are provided. Each credit card bears an elongate strip of sound recording material including a recorded code word known only to the owner of the card. A plurality of card reading devices for reproducing the code word recorded on said strip are also provided. The card reading devices each include a housing, an inlet slot in a first wall of the housing for receiving a credit card to be read, an outlet slot in a second wall of the housing for discharging a credit card, rotatable wheels within the housing and positioned such that, on rotation of the wheels, the card is transported in a straight path through the housing. The card reading device also includes sound reproducing means for reproducing the code word recorded on the strip which includes a sound reproducing head moveably mounted within the housing and moveable between a first position in which the head is spaced from the straight path and a second position in which the head is in sound reproducing association with the strip for reproducing the recorded code word. A trigger member in the device is actuated by motion of the card along the straight path and moves the sound reproducing head from the first position to the second position for reproducing the code word recorded on the strip. The device also includes listening means to permit an operator of the device to listen to the reproduced code word for comparison with a code word given orally by the card owner.
A credit card utilization system comprising a plurality of credit cards, each credit card bearing an elongate strip of sound recording material, said strip being disposed lengthwise of the credit card and including a recorded code word known only to the owner of the card, and a plurality of card reading devices for reproducing the code word recorded on said strip, said card reading devices each comprising a housing, an inlet slot in a first wall of the housing for receiving a credit card to be read, an outlet slot in a second wall of the housing for discharging a credit card from said card reading device, rotatable wheels within said housing and positioned such that a card introduced into said device is supported on the periphery thereof such that, on rotation of said wheels, said card is transported in a straight path through said housing from said inlet slot to said outlet slot, means for rotating said wheels, sound reproducing means located adjacent said straight path for reproducing the code word recorded on said strip and comprising a sound reproducing head moveably mounted within said housing and moveable between a first position in which the head is spaced from a card in said straight path and a second position in which the head is in sound reproducing association with said strip on a card in said straight path for reproducing said recorded code word, a trigger member actuated by motion of said card in said straight path for moving said sound reproducing head from said first position to said second position for reproducing the code word recorded on said strip, means for biasing said head into said first position, and listening means to permit an operator of the device to listen to the reproduced code word for comparison with a code word given orally by the card owner.
