Keywords:magnetic card? PSoC 3? four-track magnetic card?

This application note describes a four-track magnetic card reader and its implementation in PSoC 3 using the AGC feature. Magnetic cards have magnetic material, either embedded or on the exterior of the card. The magnetic head gives out a characteristic waveform when a card is swiped. When the card is swiped, the flux linked to the magnetic read head changes and produces a voltage.
