Abstract
Embodiments provide a method for transmitting data between a user terminal and another apparatus. The method has a step of generating a signal for driving an electromagnetic oscillating circuit connected to the user terminal. Additionally, the method has a step of driving the electromagnetic oscillating circuit by the generated signal to produce, by the electromagnetic oscillating circuit, a magnetic field which carries data to be transmitted from the user terminal to the other apparatus.
