Near Field Communication (NFC) is a wireless communication technology that allows short-range data transfer between devices, primarily designed for mobile and handheld devices. Developed by Philips and Sony in 2002, NFC operates based on RFID principles and has various applications including mobile payments, access control, and peer-to-peer data exchange. Advantages of NFC include convenience and secure communication, though it is limited by short operational range and slower data transfer rates.

COMMUNICATION

2. What is NFC???
• A short range, high frequency, low bandwidth and wireless
communication technology between two devices.
• Based on RFID(Radio Frequency Identification Service)
Technology.
• Mainly aimed for mobile & handheld devices.

3. 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 were given.
• 2006- Nokia 6131 was the first NFC enabled Phone.
• 2010- Samsung Nexus S was the first Android NFC
enabled Phone.

4. Working Principle
• NFC works on the principle of RFID (Radio Frequency
Identification).
• Types of Coupling in RFID:
 BackScatter Coupling
 Capacitive Coupling
 Inductive Coupling.

5. Operation Of NFC
• Near field communication is based on inductivecoupling.
• NFC works using magnetic induction between two
antennas located within each other's 'near field’.

6. Modes of
Operation

7. Modes Of
Operation
• In Active mode, both devices with NFC chip
generates an electromagnetic field and exchange
data.

8. Modes of
Operation
• In Passive mode, there is only one active device and
the other uses that field to exchange information.

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

10. Applications 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
for picking up an Internet URL from a smart label on a poster.

11. Applications 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.

12. Applications 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.

13. NFC Specifications
• 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.

14. Comparison with
Existing Technology

15. 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.

16. 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.

Technology

19. 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.
