1. A human body communication (HBC) apparatus for a near field communication (NFC) signal, the HBC apparatus comprising:
a first communicator configured to receive a first NFC signal from an NFC reader according to an NFC standard through a body in proximity to the body, wherein the first NFC signal is a signal according to the NFC standard, the first NFC signal propagates along a surface of the body, the first communicator comprises an electrode configured to receive the first NFC signal, and the electrode is a plate-shaped electrode that is parallel to the surface of the body;
an NFC processor configured to extract first data according to an NFC method from the first NFC signal received from the NFC reader through the body;
a second communicator configured to transmit a signal to a user device, wherein the second communicator comprises an NFC antenna coil configured to transmit the signal to the user device; and
a matching circuit configured to match an impedance of the electrode and an impedance of the NFC antenna coil,
wherein the first data included in the first NFC signal received from the NFC reader through the body by the first communicator is transmitted to the user device by the second communicator.
