An NFC interface with an energy management function. The NFC interface has an independent energy antenna, and the NFC interface comprises an energy management module and an energy storage module, wherein the energy management module is electrically connected to the energy storage module; and the energy management module is used for charging the energy storage module according to electric energy collected by the energy antenna, and is further used for cutting off charging to the energy storage module when the energy storage module pulls down a voltage collected by the energy antenna to a first voltage threshold value.
