Abstract

Embodiments of the invention disclose a near field communication (NFC) circuit and a terminal. The NFC circuit comprises a feeding terminal, a signal shielding unit and an NFC control unit, wherein atarget antenna receives a first signal, and the signal shielding unit shields a redundant signal in the first signal, so as to obtain a first NFC signal; during information interaction between the NFCcontrol unit and a control unit in the terminal, if the NFC control unit receives the first NFC signal, a target signal is obtained according to the first NFC signal, the target signal is sent to thecontrol unit so as to enable the control unit to work according to the target signal; and if the NFC control unit receives a control signal sent by the control unit, the NFC control unit obtains a second NFC signal according to the control signal and radiates the second NFC signal through the target antenna. The target antenna is reused, an antenna preset on the terminal is not re-designed or re-arranged, so that the NFC function can be realized on the terminal more easily.
