2. Overview :-
 NFC is one of the latest short-range high frequency wireless
communication technology that enables simple and safe exchange
of data between devices over a 10 cm distance.
 NFC-enabled devices can simply point or touch their making
application and data usage easy and convenient.

3. History :-

4.  NFC is based on RFID technology that uses magnetic field induction
to enable communication between electronic devices in close
proximity.
 For two devices (initiator/target) to communicate using NFC, one
device must have an NFC reader/writer and one must have an NFC
tag. The tag is essentially an integrated circuit containing data,
connected to an antenna, that can be read and written by the reader.
 NFC operates at 13.56 Mhz.
 Maximum transfer bit rate of 800kbps.
 No special software is required.
How NFC Works :-

NFC devices :-

6.  Active Modes :-
In this mode, both devices with NFC chip can
generate an electromagnetic field and exchange information
with each other.
 In this mode, both devices typically have their own power
supplies.
Types of Modes :-

7.  Passive Mode :-
A passive device, such as an NFC tag,
contains information that other devices can read
but does not read any information itself, so there
is only one active user.
 In this mode, the target device may draw its
operating power from the initiator provided
electromagnetic field.
Types of Modes :-

8. Application of NFC :-
 TOUCH AND GO :- Application such as access control,
where the user needs only to bring the device storing the ticket
or access code close to the reader.

9.  TOUCH AND CONFERM :- Applications such as mobile
payment where the user has to confirm the interaction by
entering a password or just accepting the transaction.
Application of NFC :-

10.  TOUCH AND CONEECT :- Linking two
NFC-enabled devices to enable peer-to-peer
transfer of data.
 A latest development is that NFC can be
used to configure Wi-Fi networks through
mobile devices.
Application of NFC :-

11.  High convenience to the user, because exchanging of
information is done just by bringing it together.
 Secure communication.
 No special software.
 No search and pair procedure.
Advantages of NFC

12.  NFC has the limitation that it can be work operate only in
shorter range around 10 cm.
 Data Corruption
 Theft.
Disadvantages of NFC

13.  Mobile handsets are the primary target for NFC and soon NFC
will be implemented in most handheld devices.
 The NFC technology enables the end users to make payments
with their mobile wallet accounts.
 NFC uses for advancements in mobile wireless technology.
