Intelligent card, near field communication device and terminal device

The utility model provides an intelligent card, a near field communication device and a terminal device. The intelligent card provided by the utility model includes an SIM card chip and an NFC (Near Field Communication) control chip. Three pins of the NFC control chip connect with a voltage pin, a grounding pin and an SWP (Single Wire Protocol) pin of the SIM card chip correspondingly. The intelligent card is provided with a terminal used for connecting an NFC antenna. According to the utility model, two protocol communications of SWP and NFC can be realized. At the same time, the physical structure of a prior terminal device does not need to change. Thus, the intelligent card, the near field communication device and the terminal device has practical applicability and universality. The intelligent card, the near field communication device and the terminal device provided by the utility model can be applied to the technical field of close range wireless communication.
