EXTERNAL ADAPTOR FOR MAGNETIC STRIPE CARD READER
1. -10. (canceled)
An adaptor in accordance with the present invention allows a conventional magnetic stripe card POS reader to receive information from contact-based or wireless sources while maintaining the concurrent ability of the reader to interact with a magnetic stripe card. In accordance with one embodiment of the present invention, the adaptor includes an inductor capable of generating a magnetic field of sufficient power to couple with a head of a magnetic stripe card reader through the housing of the reader device. In this manner, the adaptor can be positioned external to the reader device, leaving the slot of the reader accessible for conventional interactions with magnetic stripe cards. Selective inductive communication with individual heads of the reader device may exploit their differing sensitivity to external magnetic fields generated by the adaptor.

11. A method of communicating with a reader head of a magnetic stripe reader device, the method comprising:
positioning a module comprising an inductor element proximate to a housing of a magnetic stripe reader device;
applying a current to the inductor element to generate a magnetic field of sufficient strength to penetrate the housing and be sensed by a head of the reader device; and
wherein the magnetic stripe reader device further comprises a second magnetic reader head exhibiting a different sensitivity to magnetic fields than the magnetic head, the method further comprising generating a second magnetic field of sufficient strength to penetrate the housing and be sensed by the second magnetic reader head.

17. A method of selectively communicating data to a reader head of a magnetic stripe reader device, the method comprising:
positioning a first inductor and a second inductor proximate to a housing of a magnetic stripe reader device;
causing the first inductor to generate a magnetic field having a first intensity sufficient to penetrate the housing and be sensed by a more sensitive head of the reader device; and
causing the second inductor to generate another magnetic field having a second intensity sufficient to penetrate the housing and be sensed by a less sensitive head of the reader device.
