A secure NFC apparatus includes a plug-in socket, an NFC unit, and a protocol matching unit. A security module is inserted in the plug-in socket. The NFC unit communicates with the outside via non-contact NFC using signals based on an S2C protocol. The protocol matching unit determines the type of chip in the inserted security module, generates a chip identification signal according to results of the identification, and matches the protocol of the signals based on the S2C protocol, which are input to and output from the NFC unit, with the protocol of the signals, which are input to and output from the security module, according to the chip identification signal.
