Magnetically communicative card
First Claim
1. A magnetically communicative card comprising:
- a card body having a width;
a controller within the card body; and
at least one conductor located at least partially within the card body, the at least one conductor being electrically coupled to the controller for controlling a magnetic field that alternates polarity with time emanating from the at least one conductor, the magnetic field being directly detectable by a magnetic card reader without further movement of the magnetically communicative card relative to the card reader, to magnetically communicate information from the magnetically communicative card to the magnetic card reader after the card body is at least partially inserted into the magnetic card reader.

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.
