Answer:
Near Field Communication or NFC works mainly on the principle of inductive coupling or magnetic coupling.
When two conductors are oriented in such a way that even a minor change in current results in the induction of a voltage across the ends of the other given wire via electromagnetic induction, the two given conductors are considered to have inductive coupling.
