NFC is actually what we usually call near-field wireless communication technology. This technology allows two NFC-enabled devices to perform contactless data transmission and exchange data under the conditions allowed by the protocol. (Within distance of ten centimeters, the operating frequency is 13.56MHz)
The NFC function is very common in daily life, such as the transportation card swiped when taking public transportation, the meal card swiping in the canteen, and the access control card when entering the community. The NFC function has brought a lot of convenience to our life. Today, smart handheld terminal devices are also can be equipped with NFC function, so what scenarios can the NFC function of smart handheld terminal be applied to?
