Abstract:
The IC card is mounted on the read and write device and the first electrostatic induction electrode and second electrostatic induction electrode are formed facing each other. The data signal is outputted from the first transmission and reception circuit to the first electrostatic induction electrode when the data signal is transmitted from the IC card to the read and write device. Then the first electrostatic induction electrode is charged based on the data signal and the electrostatic induction signal of the opposite polarity is induced at the second electrostatic induction electrode. The inverted data signal appears at the second electrostatic induction electrode. The second transmission and reception circuit of the read and write device receives and amplifies the inverted data signal, leading to the non-contact data communication with lower energy consumption and the lower cost.
