2. Introduction
NFC is a short-range wireless
technology.
NFC provides unique advantages over
other available wireless technologies.
The design includes a near-field
transmitter and receiver to send data
from one computer to another
3. Continued…
NFC is one of the latest wireless
communication technologies
Enables the exchange of data between
devices over a distance of up to 20
centimetres.
NFC offers safe yet simple and intuitive
communication between electronic
devices.
4. History
2004 Nokia, Philips And Sony Establish
The Near Field Communication (NFC).
Nokia 6131 is the first NFC phone.
By 2013, one in five phones will have
NFC.
5. How it works?
NFC is based on RFID technology that
uses magnetic field induction to enable
communication between electronic
devices in close proximity.
NFC operates at 13.56 MHz.
For two devices to communicate using
NFC, one device must have an NFC
reader/writer and one must have an
NFC tag.
6. Applications:
Social net-working: File Sharing,
Electronic business card, Electronic money.
E-Commerce :Mobile payment, Ticketing,
Tour guiding,Boarding pass.
Identity documents: NFC's short range
helps keep encrypted identity documents
private.
NFC device can connect with Bluetooth and
Wi-Fi.

8. Benefits & Features
Not restricted to 1-to-1 communication
Multiple devices in a small area can
communicate with each other using the
same frequency.
Maximum transfer bit rate of 800kbps.
No special software is required.
Operation at a frequency of 13.5 MHz
No ethical concerns due to range.
9. Advantages of NFC:
Emerging NFC standards allow customers to quickly
purchase products and transfer secure information
by touching devices.
NFC allows companies to reduce staffing, printing,
and point of sale costs.
Google Wallet is an Android app that stores virtual
versions of your credit cards for use at checkout
when a PIN is used.
10. Disadvantages of NFC
Communication range is the main limitation
of NFC compared to Bluetooth.
NFC does not suit portable devices that
require online connectivity to another
portable device or to a fixed access point.
The placement of the antenna is more
critical. The location of the antenna has to
be indicated to the user.
11. Overcoming disadvantages
These disadvantages can be partly
overcome by combining NFC with
Bluetooth or WLAN, which on the other
hand will mean that some of the
advantages such as the lower price of
pure NFC implementation are lost.
Still, this is an important aspect in NFC
application possibilities.
12. Comparison with Bluetooth
NFC and Bluetooth are both short-range
communication technologies which are
integrated into mobile phones.
NFC sets up faster speed than standard
Bluetooth.
The maximum data transfer rate of NFC
(424 kbit/s) is slower than that of
Bluetooth V2.1 (2.1 Mbit/s).
13. Continued…
NFC has a range of less than 0.2m
while bluetooth has a range of ~10m.
NFC requires comparatively low power,
similar to the Bluetooth V4.0 low energy
protocol.
14. Continued…
The data transfer achieved by Bluetooth
is no doubt faster than that of NFC
technology, but it provides the benefit
of better security and increased
usability.
Pure NFC communication enables lower
price,since NFC is technically less
complex than bluetooth.
16. Future market for NFC
By 2013, one in five phones will have
NFC.
Nokia is active in the area of NFC since
2004.
Currently, global membership in the
NFC Forum had exceeded 140
organizations.
17. Future Hardware Development
Less power consumption
More efficient loop antenna for larger
range.
Smaller setup
Two-way communication
19. Conclusion
We conclude that NFC is a highpotential
technology for implementing ultralow power
sensors with touchbased communication with
mobile handsets.
NFC is backed by the leading mobile phone
manufacturers and is expected to penetrate into
mobile phones in near future.
This will improve the availability of NFC
technology in general and facilitate its
applicability in mobile sensor applications, too.
