Method of transmitting information from efficient communication protocol card readers to mobile devices
A method is provided of transmitting information with a communication protocol to a mobile device. A card reader is provided with a read head that has a slot for swiping a magnetic stripe of a card, an output jack and device electronics that includes a microcontroller. The read head is used to read data on a magnetic stripe of a card. A raw magnetic signal is produced indicative of data stored on the magnetic stripe. The raw magnetic head signal is converted into a processed digital signal that the microcontroller can interpret. A synchronous Manchester encoded stream is produced that makes a greater number of 0 crossings. A Manchester encoded stream output jack signal is delivered to the mobile device through the output jack.
