Systems And Methods For Creating Dynamic Programmable Magnetic Stripes

摘要

Conventional magnetic stripe cards are encoded with static magnetic patterns. To act like many different magnetic stripe cards, a programmable dynamic magnetic stripe card disclosed. The programmable dynamic magnetic stripe card includes a solenoid coil for generating a magnetic field and solenoid coil driver circuitry for driving the solenoid coil to generate a magnetic field. To improve the quality of the magnetic field generated, a biasing magnet is placed adjacent to the solenoid coil.
