2. What Is NFC ?
 NFC is a short range high frequency wireless
communication technology.
 NFC is based on RFID(Radio Frequency Identification)
technology at 13.56 MHz.
 Its Operating distance is typically up to 10 cm.
 Data exchange rate today is upto 424 kilobits/s.

3. Modes of NFC

1.
There are mainly two modes of NFC.
Active Mode: In Active mode, both devices with NFC
chip generates an electromagnetic field and
exchange data.
Two NFC enabled devices transfering data in active mode

4. 2. Passive Mode:In Passive mode, there is only one active
device and the other uses that field to exchange
information.
A NFC-enabled mobile phone is paired with a RFID-tagged "smart poster“
operating in passive mode

5. Tags of NFC
The tag is a simple, thin
device containing an
antenna and a small
amount of memory. It is a
passive device, powered by
a magnetic field.
Depending on the tag type,
the memory can be read
only, rewritable, or writable
once.
There are mainly four type of Tags.
1. Tag Type 1
2. Tag Type 2
3. Tag Type 3
4. Tag Type 4

6. NFC Tag Type 1
 Type 1 Tags are cost effective and ideal for many NFC

applications.
Based on ISO-14443A standard
Read and rewrite capable; also users can configure the
tag to be read-only
96 bytes of memory, expandable up to 2 kB
Communication speed 106 kbits/s
No data collision protection

7. NFC Tag Type 2
 Type 2 Tags are similar to Type 1 Tags and are derived from

to be read-only
96 bytes of memory, expandable up to 2 kB
Communication speed 106 kbits/s
Anticollision support

8. NFC Tag Type 3
 Type 3 Tags are derived from the nonsecure parts of Sony

FeliCa tags. These tags are costlier than Types 1 and 2.
Based on the Japanese Industrial Standard (JIS) X 6319-4
Preconfigured at manufacture to be either read and
rewritable, or read-only
Variable memory, up to 1 MB per service
Supports two communication speeds: 212 or 424 kbits/s
Anticollision support

Supports three different communication speeds: 106, 212,
or 424 kbits/s
Anticollision support

10. Application
1. 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.
The
screensho
t from a
mobile
device
showing
the
confirmat
ion
message.

11. 2.Touch and Connect:Linking two NFC-enabled
devices to enable transfer of data such as downloading
music, exchanging images.
Data transfer
via NFC

12.  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.
Touch and go
Mode of application

13. 4. Some other applications of NFC:
I. Access controls in office, hotels, airports, print
receipts to printer.
II. Download music or video from a smart poster.
III. Exchange business cards, Pay bus or train or air fare,
Parking Tickets, Pay and purchase at Point of Sale
Terminals

15. ADVANTAGES OF NFC
 High convenience to the user, because the data


exchange is done by bringing two mobiles together.
Reduces cost of electronic issuance .
Secure communication.
No special software.
No manual configuration and settings.
No search and pair procedure.

16. DISADVANTAGES 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.

17. SOME DEVICES USING NFC
TECHNOLOGY
 Nexus S
 Google Nexus S 4G
 Samsung Galaxy S II
 Samsung Galaxy Note
 Galaxy Nexus
 Nokia 6212 Classic
 Nokia 6131 NFC
 Nokia C7

18. 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.
 On May 2, 2011, RIM announced the Blackberry Bold
9900, a new device that will use NFC technology.
 Recently, Microsoft announced that all Windows
Phone 8 devices will make use of the NFC technology.

19. 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.
