PURPOSE: A key input device and an operation method of an NFC are provided to selectively connect various types of input devices in an NFC communication method. CONSTITUTION: A keypad unit (180) comprises multiple keys. A second NFC antenna unit (155) and a second NFC transceiver (160) perform the mobile unit and NFC. A charge unit (165) converts an alternative current into a direct current through an electric wave. An analysis unit (170) determines a key value corresponding to the pressed key in the keypad unit. The analysis unit supplies the determined key to the second NFC transceiver.
