Abstract
A dangle, which plugs into the audio/earpiece jack of host devices, allows them to accept payment cards as a point of sale (POS) terminal. It contains a magnetic stripe (magstripe) card reader, a smart card reader, and/or a proximity card reader (reader(s)); a microprocessor or microcontroller (CPU); and a circuit for drawing power from a digital audio signal (power circuit). Payment card data is collected by the reader(s), passed to the CPU where it is encrypted, encoded, and modulated, sent to the host device through the Microphone input contact of the audio/earpiece jack, then transmitted via one the host device's networks to a merchant account provider for processing. A digital audio signal, constantly generated by the host device, provides power to the dongle via the power circuit. The power circuit converts the digital audio signal to stable DC power with the appropriate voltage for powering the dongle's other components.
