Near field communication (NFC) is a set of standards for smartphones 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>Template:Cite web</ref> Communication is also possible between an NFC device and an unpowered NFC chip, called a "tag".<ref name=Gadgetronica>Template:Cite web</ref>

NFC standards cover communications protocols and data exchange formats, and are based on existing radio-frequency identification (RFID) standards including ISO/IEC 14443 and FeliCa.<ref name=NFCForumSpecList>Template:Cite web</ref> The standards include ISO/IEC 18092<ref name=ISO18092>Template:Cite web</ref> and those defined by the NFC Forum, which was founded in 2004 by Nokia, Philips and Sony, and now has more than 160 members. The Forum also promotes NFC and certifies device compliance.<ref name=AboutNFCForum>Template:Cite web</ref>
