3. 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 .

4. 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.

5. 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

6. 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 .

7. 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.

11. 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).

13. 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.

18. 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.

19. AT PRESENT THERE ARE AROUND 160
MEMBERS IN NFC FORUM

20. 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.

23. 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.
