Difference between revisions of "Near Field Communication"

'''Near field communication''' ('''NFC''') is a set of standards for [[smartphone]]s and similar devices to establish [[radio]] communication with each other by touching them together or bringing them into close proximity, usually no more than a few centimeters. Present and anticipated applications include contactless transactions, data exchange, and simplified setup of more complex communications such as [[Wi-Fi]].<ref name=WhatIsNFC>{{ cite web |title=What is NFC?|url=http://www.nfc-forum.org/aboutnfc/|publisher=NFC Forum|accessdate=14 June 2011 }}</ref> Communication is also possible between an NFC device and an unpowered NFC [[integrated circuit|chip]], called a "tag".{{ cite web |url=http://www.gadgetronica.com/blog/near-field-communication.html |title=NFC&nbsp;— future of wireless communication| author= Nikhila |date=26 October 2011 |publisher= Gadgetronica }}
