    • INTRODUCTION  Near field communication (NFC) : It is a short-range communication technology that enables devices to exchange information with other NFC-enabled devices or certain NFC supporting cards .  It can be done by touching the devices together or bringing them into close proximity, usually no more than a few centimeters.  NFC operates at 13.56 MHz on ISO/IEC 18000-3 air interface and at rates ranging from 106 kbit/s to 424 kbit/s .
    • HISTORY  NFC traces its roots back to Radio-frequency identification, or RFID.  RFID allows a reader to send radio waves to a passive electronic tag for identification and tracking.  1983 : The first patent to be associated with the abbreviation RFID was granted to Charles Walton.  2004 : Nokia, Philips and Sony established the Near Field Communication (NFC) Forum  2006: Nokia 6131 was the first NFC phone .  2011: NFC support becomes part of the Symbian mobile operating system with the release of Symbian Anna version.
    • HOW NFC WORK’S  Near-field communication uses magnetic induction between two loop antennas located within each other's near field, effectively forming an air-core transformer. It operates within the globally available and unlicensed radio frequency ISM band of 13.56 MHz , with a bandwidth of 14KHz .  NFC always involves an initiator and a target .  There are two modes of communication :  Passive communication mode  Active communication mode
    • PASSIVE COMMUNICATION MODE  The initiator device provides a carrier fields and the target device answers by modulating the existing field. In this mode, the target device may draw its operating power from the initiator-provided electromagnetic field, thus making the target device a transponder .
    • ACTIVE COMMUNICATION MODE  Both initiator and target device communicate by alternately generating their own fields. A device deactivates its RF field while it is waiting for data. In this mode, both devices typically have power supplies.
    • EXAMPLES Passive communication Active communication

    • MIFARE CARD
    • COMPARISION OF NFC WITH BLUETOOTH  NFC and Bluetooth are both short-range communication technologies .  NFC operates at slower speeds than Bluetooth, but consumes far less power and doesn’t require pairing.  NFC sets up faster than standard Bluetooth.  The connection between two NFC devices is automatically established quickly: in less than a tenth of a second.  The maximum data transfer rate of NFC (424 kbit/s) is slower than that of Bluetooth V2.1 (2.1 Mbit/s).
    • USES AND APPLICATIONS  There are three main use cases for NFC :  Card emulation : the NFC behaves like an existing contactless card .  Reader mode : the NFC device is active and read a passive RFID tag.  P2P mode : two NFC can communicate and exchange communication.

    • NFC FORUM (RESPONSIBLE FOR NFC PROTOCOLS) NFC is a standard defined by the NFC Forum, a global consortium of hardware, software / application , credit card companies ,banking ,network providers , and others who are interested in the advancement and standardization of this promising technology.
    • AT PRESENT THERE ARE AROUND 160 MEMBERS IN NFC FORUM
    • SECURITY ASPECTS  Applications makers will use higher-layer cryptographic protocols (e.g., SSL) to establish a secure channel.  Application providers and transaction parties, who will need to use anti-virus and other security solutions to prevent spyware and malware from infecting systems.  Customers, can also protect their personal devices and data with passwords, keypad locks, and anti-virus software.
    • NFC-ENABLED HANDSETS Android  HTC One XL  Nexus S  Google Nexus S 4G  Samsung Galaxy S II (not all versions)  Samsung Galaxy Note (not all versions)  Huawei Sonic  Sony Xperia S BlackBerry  Blackberry Bold 9790  BlackBerry Bold 9900/9930  BlackBerry Torch 9810/9860  Blackberry Curve 9350/9360/9370
    • Bada  Samsung Wave 578  samsung wave Y Ovi store/S60 & J2ME  Nokia 600  Nokia 603  Nokia 700  Nokia 701  Nokia C7  Nokia Astound  Nokia Oro Window Benq T80
    • CONCLUSION  Market research suggests that over the next few years, Near Field Communication (NFC) technology will be in use all around us.  Shipments for NFC enabled phones are forecasted to reach 700 million units in 2016.  For consumers, the technology will become omnipresent in our lives, and NFC-enabled mobile phones will emerge as our primary consumer ID credential.
