Near Field Communication (NFC) is a new technology. Devices using NFC technology (such as mobile phones) can exchange data when they are close to each other. It is developed from the integration of contactless radio frequency identification (RFID) and internet technology. By integrating the functions of sensor card reader, sensor card and point-to-point communication on one chip, the functions of mobile payment, electronic ticketing, access control and mobile identity are realized by using mobile terminals.
