Near field communication (NFC) technology lets smartphones and other enabled devices communicate with other devices containing a NFC tag. This is a set of communication protocols that enable two electronic devices, one of which is usually a portable device such as a smartphone, to establish communication by bringing them within 4 cm (1.6 in) of each other. Essentially, it’s a way for your phone to interact with something in close proximity.
The most important advantage of NFC technology, in comparison with Bluetooth, is its higher speed in data transferring.
