This technology evolved from contactless radio frequency identification (RFID) and is backward compatible with RFID. It was first developed by Sony and Philips, and is mainly used to provide M2M (Machine to Machine) communication in handheld devices such as mobile phones. Because of the natural security of near field communication, NFC technology is widely used in POS mobile payment, bus cards, bank cards, access cards, water cards and other occasions.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eConnection Diagram\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/image.dfrobot.com\/image\/data\/DFR0231-H\/Introduction\/1.jpg\" original=\"https:\/\/image.dfrobot.com\/image\/data\/DFR0231-H\/Introduction\/1.jpg\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eGravity: UART \u0026amp;
