Near Field Communication

Near field communication (NFC) is the set of protocols that enable electronic devices to establish radio communication with each other by touching the devices together, or bringing them into proximity to a distance of typically 10cm or less. All NFC-enabled smartphones can be provided with dedicated apps including 'ticket' readers as opposed to the traditional dedicated infrastructure that specifies a particular (often proprietary) standard for stock ticket, access control and payment readers.
