Abstract
A card reader device is provided that includes a housing having a slot for swiping a magnetic stripe of a financial transaction card to complete a financial transaction between a buyer and seller. A read head is positioned in the housing. The read head reads data stored on the magnetic stripe and produces a signal indicative of data stored on the magnetic stripe. The read head has sufficient impedance to set amplitude of a signal indicative of data stored on the magnetic stripe. An output jack is adapted to be inserted into a microphone input associated with a mobile device for providing the signal indicative of data stored on the magnetic stripe to the mobile device.
