CARD READER WITH POWER EFFICIENT ARCHITECTURE THAT INCLUDES A POWER SUPPLY AND A WAKE-UP CIRCUIT

摘要

These and other objects of the present invention are achieved in a card reader with a read head positioned in a housing. The read head is configured to be coupled to a mobile device and 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. A power supply is coupled to wake-up electronics and a microcontroller. 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.
