Abstract
Dynamic magnetic stripe communications devices are provided as magnetic stripe emulators. A device, such as an application specific integrated circuit, may include a waveform generator that retrieves data from memory and may generate waveforms from the retrieved data to be communicated by the magnetic stripe emulator and received by a magnetic stripe reader.
