Near field communication technology (NFC) is a combination of radio frequency identification (RFID) and networking technologies. It is a unique wireless technology that enables easy and convenient short-range communication between electronic devices(around 4cm). It connects all types of consumer devices and facilitates easy communication among them. It acts as a secure gateway and allows consumers to use NFC enabled mobile devices to store and access all kinds of data. If two NFC enabled devices are brought closer to one another, they can automatically initiate network communication without the need for any preconfiguration or setup. NFC enabled consumer devices can be used to store and exchange any types of personal data like messages, photographs, MP3 files, and so on. Following features of NFC make it very suitable for IoT communication:
◾ Ease of use
◾ Instant natural connectivity
◾ Zero configuration
◾ Smart key access
