3. WHAT IS NFC?
 NFC or Near Field Communication is a short range high
frequency wireless communication technology.
 A radio communication is established by touching the two
phones or keeping them in a proximity of a few
centimeters.
 NFC is mainly aimed for mobile or handheld devices.
 NFC is an extension of Radio frequency identification or
RFID technology.
 RFID is mainly used for tracking and identification by
sending radio waves.
 The design includes a near-field transmitter and receiver to
send data.

4. EVOLUTION OF NFC
 Evolution of NFC 2002- The technology was jointly
developed by Philips & Sony.
 2004- Nokia, Philips and Sony established the NFC Forum.
 2006- Initial specifications for NFC tags are given.
 2006- Nokia 6131 was the first NFC enabled Phone.
 2012- Google Nexus was the first Android NFC enabled
Phone.

5. HOW NFC WORKS?
WORKING PRINCIPLE:
 NFC works on the principle of RFID (Radio Frequency
Identification).
OPERATION OF NFC:
 Operation Of NFC Near field
communication is based on
inductive-coupling.
 NFC works using magnetic
induction between two antennas
located within each other's ‘near field’.

MODES OF
OPERATION
PASSIVE
MODE
ACTIVE
MODE

8. MODES OF OPERATION
 In Active mode, both devices with NFC chip
generates an electromagnetic field and exchange
data.

enabled
devices

data in
active mode

9. MODES OF OPERATION
 In Passive mode, there is only one active device
and the other uses that field to exchange
information.

10. NFC APPLICATION
 NFC applications can be split into the
following three basic categories:
Touch and Go
Touch and Confirm
Touch and Connect

11. APPLICATION OF NFC
 Touch and Go
Applications such as access control or transport/event
ticketing, where the user needs only to bring the device
storing the ticket or access code close to the reader.
Example: picking up an Internet URL from a smart label on
a poster.

application

12. APPLICATION OF NFC
Movie buff
gathering
info about a
movie
using his NFC
enabled
Mobile Phone

13. APPLICATION OF NFC
 Touch and Confirm
Applications such as mobile payment where the user has to
confirm the interaction by entering a password or just
accepting the transaction.

14. APPLICATION OF NFC
 Touch and Connect
Linking two NFC-enabled devices to enable peer to peer
transfer of data such as downloading music, exchanging
images or synchronizing address books.

transfer
via NFC

15. NFC SPECIFICATION
 NFC operates at 13.56 MHz and at rates ranging from 106
kbit/s to 424 kbit/s.
 NFC always use an initiator and a target; the initiator
actively generates an RF field that can power a passive
target.

16. SOME DEVICES USING NFC
TECHNOLOGY
 Past & current smartphones:
 Nokia 6131
 Google Nexus
 Blackberry
 Samsung Galaxy S 2
 Samsung Galaxy Note
 Nokia Astound
 Future smartphones:
 Windows Phones
 HTC
 LG

17. NFC ENABLED MOBILE WITH SD
& SIM CARD
o Individuals wishing to use near field communication must
own a compatible device or purchase an individual SIM
card or microSD card with an NFC chip installed on it.

18. USES OF NFC

19. BEFORE & AFTER
Previously Used Methods
Current & Future Methods

20. ADVANTAGES OF NFC
 Not restricted to 1-to-1 communication, it is 2-way
communication.
 Multiple devices in a small area can communicate with each
other using the same frequency.
 No special software is required.
 Secure level is high due to encoding system.
 High recognition speed and low recognition error.
 No manual configuration and settings.
 No search and pair procedure.

21. LIMITATIONS OF NFC
 The system has the limitation that it can be operated only
with devices under a short range i.e around 10 cm.
 The data transfer rate is very less at about 106kbps, 212
kbps and 424kbps.

22. CONCLUSION
 Mobile handsets are the primary target for NFC and soon
NFC will be implemented in most handheld devices. Even
though NFC have the shortest range among radio frequency
technologies, combining them with existing technologies
like Bluetooth or Infrared can increase its range of
applications.
