Brief introduction of near field communication

Near field communication, also known as near field communication, is a short-distance high-frequency wireless communication technology, which allows non-contact point-to-point data transmission and data exchange between electronic devices. This technology evolved from the contactless radio frequency identification (RFID) jointly developed by Philips and Sony, and is based on RFID and internet technology. Near-field communication is a short-range high-frequency radio technology, which works in the range of 20 cm, the frequency is 13.56 MHz, and the transmission speed is 106 kbit/s, 2 12 kbit/s or 424 kbit/s. ..

Near field communication service combines near field communication technology and mobile communication technology, and realizes many functions such as electronic payment, identity authentication, ticketing, data exchange, anti-counterfeiting and advertising. This is a new service in the field of mobile communication. Near-field communication service has changed the way users use mobile phones, made users' consumption behavior gradually electronic, and established a new consumer and business model.

The application of Near Field Communication (NFC) technology has been widely concerned around the world, and different roles such as telecom operators and mobile phone manufacturers at home and abroad have launched application pilots one after another, and some international associations have also actively promoted standardization. According to the prediction of relevant institutions in the industry, the mobile phone application based on near field communication technology will become the next killer application of mobile value-added services.
