Abstract
A magnetically communicative card (200) has a ferrite core (302) extending substantially the width (201) of the card body (203) and has a conductor (408) wound around the ferrite core for the entire length of the ferrite core. Embedded within the card body is a controller (208) that controls a varying magnetic field emanating from the conductor to mimic a varying magnetic field produced by a conventional magnetic stripe card. Optionally, the card includes a sensor to sense a signal intercepted by the conductor from a varying magnetic field emanating from another device. The controller reads the sensed signal to receive communication from the other device. A magnetically communicative card (400, 500) is alternatively flexibly attached and detachably coupled to an electronic wallet (402, 502) to produce an apparatus (405, 501). A wireless communication interface (523) is alternatively carried by the magnetically communicative card and the electronic wallet to provide wireless reconfiguration of the magnetically communicative card remotely.
