An electronic card that, once activated, can drive a set of user data from a first secure microprocessor through a signal line to a second processor, process the set of user data in the second processor to generate a series of digital transaction signals, drive the series of digital transaction signals into a RC specialty circuit, convert the series of digital transaction signals into two distinct analog waveform signals, and drive the two distinct analog waveform signals along at least two tracks such that the first analog signal and the second analog signal cancel each other magnetically so that the resulting magnetic flux at a target broadcast area replicates the magnetic field created in a magnetic stripe. |
