2.  It stands for Near Field Communication.
 It is a short range, high frequency, low bandwidth and wireless
communication technology between two device over about 10 cm.
 It is based on RFID Technology.
 It allows users to seamlessly share content between digital devices,
pay bills wirelessly or even use their cellphone as an electronic
traveling ticket on existing contactless infrastructure already in use
for public transportation.

4. HISTORY
2002- Sony and Philips agreed on establishing a
new technology specification and created a technical
outline on March 25, 2002.
2004-Nokia, Philips and Sony established the Near
Field Communication (NFC) Forum.
2006- Initial specifications for NFC Tags.
2006- Nokia 6131 was the first NFC phone.
2010- Samsung Nexus S: First Android NFC phone.
2011- Google I/O "How to NFC" demonstrates NFC
to initiate a game and to share a contact, URL, app,
video, etc.
2013 Samsung and Visa announce major
partnership to develop mobile payments.

5. Working Principle
• NFC work on the principle of RFID (Radio
Frequency Identification).
• Types of coupling in RFID:
Backscatter coupling
Capacitive coupling
Inductive coupling

6. Operation of nfc
• It is based on inductive coupling
• NFC works using magnetic induction between two
antennas located within each others near field

7. MODES OF
OPERATION
PASSIVE
MODE
ACTIVE
MODE

8. In Active mode, both devices with NFC chip generates an electromagnetic field
and exchange data.
ACTIVE MODE

9. In Passive mode, there is only one active device and the other uses that field to
exchange information.
PASSIVE MODE

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

11. 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 for picking up an
Internet URL from a smart label on a poster.
Touch and Go

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

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

14. Using NFC to Pay for Parking Using an NFC-enabled Phone to Exit a
London Train Station

15. A Bus Rider in China Uses Her
Phone to Redeem Her Pass
Using an NFC-enabled Phone for
Transport Entry in Japan

16. “Touch and Travel” with an NFC-
enabled Phone in Germany

19. Comparison with Existing
Technology

20. Advantages Of NFC
• High convenience to the user, because the data
exchange is done by bringing two mobiles together.
• Secure communication.
• No special software.
• 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. Future of NFC
• New generations of iPhone, iPod and iPad products
would reportedly be equipped with NFC capability
which would enable small-scale monetary
transactions.
• Recently, Microsoft announced that all Windows 8
Phone devices will make use of the NFC technology.
