Abstract
A card reader is provided with a read head with a slot and is configured to be coupled to a mobile device and has a slot for swiping a magnetic stripe of a card. The read head reads data on the magnetic stripe and produces a raw magnetic signal indicative of data stored on the magnetic stripe. A power supply is coupled to wake-up electronics and a microcontroller. An output jack is adapted to be inserted in a port of the mobile device and deliver an output jack signal to the mobile device. The wake-up electronics is powered by a microphone bias of a mobile device.
