COST EFFECTIVE CARD READER CONFIGURED TO BE COUPLED TO A MOBILE DEVICE

摘要

A 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 with an analog front-end and a microcontroller. The analog to digital front end is coupled to a processing element in the microcontroller. The analog to digital front end receives a raw magnetic head signal and converts it into a processed digital signal that the microcontroller can interpret. The microcontroller produces a signal. 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.
