3. Introduction
Near Field Communication (NFC)
refers to:
 Short-range wireless connection (a
few centimetres).
Frequency : 13.56 MHz
Max. Bandwidth : 424Kbits/sec
Simple and safe.

5. Operation
Based on contactless technologies and Radio
Frequency Identification (RFID), so you need a
reader and a tag.

6. NFC TAG
 An RFID device - silicon memory chip connecting to external
antenna. Tag does not have its own power source (passive).
The passive tag absorbs a small portion of the energy emitted
by the reader (phone), and starts sending modulated
information when sufficient energy is acquired from the RF
field generated by the reader.

7. Operation Of NFC
NFC devices communicate via magnetic field
induction, where two loop antennas are located within
each other's near field, effectively forming an air-core
transformer.
The reader continuously generates an RF carrier sine
wave (at 13.56 MHz), watching always for modulation
to occur. Detected modulation of the field would
indicate the presence of a tag.

8. Active vs Passive Device
Devices containing power sources are called as
active
Mobile phone
NFC reader
Devices without any available power sources are
called as passive
RFID tag

9. Modes of Operation

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

11. Touch and Go
 Applications such as access control or
transport ticketing, where the user
needs only to bring the device storing
the ticket or access code close to the
reader

12. 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.
Speakers (touch to
connect)

13. Touch and Confirm
 Applications such as mobile payment where the
user has to confirm the interaction by entering
a password.

14. Comparison With Existing
Technologies

15. Current capabilities
 Sending simple data like applications, contact
information, send business cards, various files .
 Payment.

16. Future of NFC
NFC powered Devices are smartcards for payment!

17. NFC powered Devices are contactless security cards!

18. Read NFC information Tags with your mobile and
know everything!

19. Smart Keys to open car doors

20. Significantly more secure online shopping

21. Benefits of NFC
 Ease of use (Very familiar to people, only
touch).
 No manual configuration and settings.
 No search and pair procedure.
 No special software.
 Automating Coupling.
 Inherent Security.

22. Disadvantages of NFC
 The system has the limitation that it can be
operated only with devices under a short range.
 The data transfer rate is very less.

23. Conclusion
 NFC will provide convenience and added
benefit for both the consumer and retailer.
