1. A card reader, comprising:
- a housing that includes a read head;
a jack coupled to the housing adapted to be inserted into a microphone input associated with a mobile device, the read head including a slot for swiping of a magnetic stripe of a buyer'"'"'s financial transaction card with the slot in response to a financial transaction between a buyer and seller, the read head reading data on the magnetic stripe and producing a signal indicative of data stored on the magnetic stripe; and
an electronic system that includes a card reader circuit, a communication subsystem, a control unit, a monitor system to manage card reader behavior between power cycles, a pathway system, and a power subsystem that in operation receives a bias voltage from a mobile device, wherein following the control unit booting up, the communication subsystem checks a status bit in the monitor system, with control unit being notified of the electronic system awakening and forcing a power cycle.
