ABSTRACT:
A reader/writer credit card modular assembly wherein a T-shaped vertically disposed rail member provides accurate positioning of a credit card relative to a read/write transducer and to a timing track transducer through a reference plane established by means of horizontally disposed pins carried by the rail member. The credit card is vertically supported on the pins which in conjunction with a built-in tool or gauge member adjustable parallel to the card enables accurate preadjustment for a plurality of electromagnetic transducer heads arranged to be moved across the front surface of the credit card effective thereby to read from or write upon the credit card in synchronism with a prerecorded timing track disposed adjacent and parallel to the credit card.
