    摘要： A card reader has a read head positioned in the housing. The read head is configured to be coupled to a mobile device. The read head 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. Device electronics are provided that include a microcontroller. The device electronics receives a raw magnetic head signal and converts it into a processed digital signal that the microcontroller can interpret. The microcontroller produces a synchronous Manchester encoded stream that makes a greater number of 0 crossings. An output jack is adapted to be inserted in a port of the mobile device and deliver a Manchester encoded stream output jack signal to the mobile device.
