A reduced-power dynamic magnetic transducer system includes a magnetoresistive read head, a low duty cycle pulse generator to supply power to the head, a signal processor, and a controller. As a data-bearing card is moved adjacent to the magnetoresistive read head, the pulse generator actuates the read head, thereby providing an intermittent signal representative of data recorded on the card. The intermittent signal is processed by the signal processor to reconstruct the original recorded data. The reconstructed data is utilized by the controller in conducting transactions with a user of the system.
