Zusammenfassung:The utility model provides an NFC tag and NFC electronic equipment. The NFC tag comprises two serially connected depletion mode N-channel MOSFETs and a voltage conversion circuit used for converting the voltage of a power supply battery. After being serially connected with each other, the two depletion mode N-channel MOSFETs are connected in parallel between the two connecting wires of an NFC antenna and an NFC chip. The input end of a voltage conversion circuit is connected with the power supply battery. The output end of the voltage conversion circuit is connected with the grids of the two depletion mode N-channel MOSFETs. When the power supply battery is full of electric power, the output voltage of the voltage conversion circuit enables the disconnection states of both the drain electrodes and the source electrodes of the two depletion mode N-channel MOSFETs. When the power supply battery is short of electric power, the output voltage of the voltage conversion circuit enables the connection states of both
