Near Field Communication (NFC), also referred to as Near Field Communication or Near Field Communication, is a set of communication protocols that allows two electronic devices to communicate within a few centimeters of each other. NFC, like the e-ticket smart cards of the past, will allow mobile payments to replace or support such systems. NFC is used in social networks to share contact information, photos, videos or files. NFC-enabled devices can act as electronic identity cards and key cards.
