NFC, also known as short-range wireless communication, is a short-range high-frequency wireless communication technology that allows contactless point-to-point data transmission (within ten centimeters) between electronic devices to exchange data. The data can be exchanged among different electronic products only by touching. Unlike a contactless IC card, NFC can perform bidirectional communication. As long as the product supports NFC, the data can be read or written, and communication can be carried out between other intelligent portable products such as mobile phones.
