Near-field communication (NFC) is a set of communication protocols that enables communication between two electronic devices over a distance of 4 centimetres (1.6 in) or less.[1] NFC offers a low-speed connection through a simple setup that can be used for the bootstrapping of capable wireless connections.[2] Like other proximity card technologies, NFC is based on inductive coupling between two electromagnetic coils present on a NFC-enabled device such as a smart phone
