Abstract
A system for providing information to a magnetic card reader. The system comprises an antenna (in one embodiment comprising a multi-purpose antenna or an antenna module) and a microprocessor for applying a differential signal to the antenna. The differential signal represents data stored in a memory segment of the microprocessor or in a memory connected to the microprocessor. The antenna transmits an alternating magnetic field representing the information the alternating magnetic field is responsive to the differential signal and received by the magnetic card reader.
