2. Near Field Communication(NFC) :
NFC is a technology developed in 2002. It is also called Near Field Communication Technology. When 2 devices having internet and NFC technology are present in a close vicinity (4 cm), they can exchange data. This is based on inductive coupling between antennas of the devices.
