Abstract

In this paper, we propose a new magnetic field coupling scheme which is applied in mobile payment system. The coil coupling model of mobile payment system with the 2kHz is established. Based on the principle of magnetic flux variation, we calculate and analyze the magnetic flux density and the coupling voltage in different distances. We mainly simulate the relationship between the coupling voltage and the distance from the transmit coil to the coupling coil and that between the coupling voltage and some different excitation signals.
