Card reader device for a cell phone and method of use
DC CAFCFirst Claim
1. A card reader device for reading a card having data stored on a magnetic stripe incorporated into the card the device comprising:
- a read head for passing a magnetic stripe of a card by to read data stored on a magnetic stripe and for producing a signal indicative of data stored on a magnetic stripe;
a signal setting device for setting an amplitude of the signal indicative of data stored on a magnetic stripe; and
an output jack adapted to be inserted into a microphone input associated with a cell phone for providing the signal indicative of data stored on a magnetic stripe to a cell phone.

Abstract
A card reader device for reading a card having data stored on a magnetic stripe incorporated into the card is disclosed in which the card reader device comprises a read head for passing a magnetic stripe of a card by to read data stored on a magnetic stripe and for producing a signal indicative of data stored on a magnetic stripe, a signal setting device for setting an amplitude of the signal indicative of data stored on a magnetic stripe, and an output jack adapted to be inserted into a microphone input associated with a cell phone for providing the signal indicative of data stored on a magnetic stripe to a cell phone. Data stored on the card and sensed by the card reader device is decoded by components such as a microphone amplifier, an analog to digital converter, and a microprocessor already resident in a cell phone.
