1. A mobile device for communicating with a magnetic reader head of a POS device, said mobile device comprising:
a housing;
an output connection accessible on said housing;
a memory coupled to said housing;
a processor coupled to said housing, said processor in communication with said memory and said output connection, said processor configured to transmit a first signal to said output connection; and
a transmitter coupled to said output connection and configured to convert said first signal received via said output connection from said processor to a second signal and wirelessly output into a magnetic field, wherein said processor is configured to:
receive, and store in said memory, a first data file containing data corresponding to each standard field in at least one of an ISO/IEC 7813 Track 1-compliant record and an ISO/IEC 7813 Track 2-compliant record; and
subsequent to storing the first data file, cause said transmitter to wirelessly transmit a changing magnetic field of sufficient strength to be received remotely by the magnetic reader head of the POS device, wherein the changing magnetic field has a waveform corresponding to polarity changes in the first data file.
