Abstract
A system for use with a mag-stripe card for transducing signals and performing predetermined transaction processing to record fresh data on the card. A closed-end slot is defined for guiding the card in manual motion. Offset record (broad path) and read (narrow path) transducers are mounted in a relationship to afford increased tolerances. Optical sensors manifest card positions as data for a processor to control and sequence proper operation. The processor also receives confirmatory read signals to verify proper recording on a card.
