Introduction
Communication – Now & Before :
 Communication is the activity of sharing
any kind of information..
 Over the years we are surrounded by
technologies like
mobile, internet, computer etc..
 Scientists are trying to combine
communication with technology..
What is Near Field Communication
 Near Field Communication (NFC) is a new
short-range, standards-based wireless
connectivity technology, that uses magnetic
field induction to enable communication
between electronic devices in close proximity.
 It is mainly aimed for Handheld devices like
Smartphone and similar devices.
 It is based on RFID [Radio-frequency
identification]
What is RFID:
 Radio-frequency
identification (RFID) is the
wireless non-contact use of
radio-frequency
electromagnetic fields to
transfer data
 Its purpose is to
automatically identify and
track tags attached to
objects.
 The tags contain
electronically stored
information.
Quick history
1983
• The first patent to be associated with the abbreviation RFID was
granted to CharlesWalton.
2004
• Nokia, Philips and Sony established the Near Field Communication
(NFC) Forum.
2011
• First mobile phone( Nokia 6131) with NFC released by NOKIA.
2010
• Samsung Nexus S: First Android NFC phone.
2011
• NFC support becomes part of the Symbian mobile operating system and
Blackberry OS.
Partners
Working Principles and Features
 NFC is an extension of Radio frequency identification (RFID)
technology that combines the interface of a smartcard and
a reader into a single device.
 This allows two-way communication between
endpoints, where the earlier systems were one-way only.
 For two devices to communicate using NFC, one device
must have an NFC reader/writer and one must have an NFC
tag
 It allows for simplified transactions, data exchange, and
wireless connections between two devices
Working Principles and Features
 A radio communication is established by touching the two
phones or keeping them in a proximity of a few centimetres
(up to 10 cm) .
 Supported data rates: 106, 212 and 424 Kbit/s
 NFC use an initiator and a target.The initiator actively
generates an RF field that can power a passive target.
 Allows communication between
o Two powered (active) devices
o Powered and non self-powered (passive) devices
Modes of Operation
1. Card Emulator Mode
(Passive Mode) :
This mode emulates a traditional
smart card (such as Mastercard or
Visa) and makes this mode
convenient because of the
already existing setup for the
contactless payments by these
smartcards companies.Thus NFC
enabled mobile phones becomes
a credit card.
Modes of Operation
2. Peer to Peer (P2P) Mode:
P2P offers interaction between
two active NFC-equipped
devices such as phones.
Like Using this mode, one could
make payments to another
individual or business just by
tapping the two phones
together
Modes of Operation
3. Reader Mode :
This allows the phone to read
passive RFID tags on
posters, stickers. For
instance, one could tap his
phone on the reader tag in a
movie poster and it would begin
playing the movie
trailer, provide theatre
times, locations, and so on.
Application of NFC
Smart Posters
 An object that has, affixed to or embedded
in it, one or more readable NFC tags with
NDEF messages stored in them.
 Each tag is read when an NFC device is held
close to it
 Location wise information
 Trailers &Tickets booking
 Billboard, garment tag, magazine
page, even a three-dimensional object
Application of NFC
NFC and Mobile Payment
A customer makes his payment through
mobile phone using NFC
 NFC phone will open wallet application
 At check out, wallet will display all
credit/debit cards in wallet for payment
 Customer will select card for payment
 Wallet will show the confirmation page
with the check out basket
 Wallet will connect to retailer back end for
authorization and display tracking
information
Application of NFC
Peer-to-peer
Connection Handover : A handover use case is the
exchange of configuration information via the NFC
link to easily establish a connection over (for e.g.
Bluetooth or Wi-Fi ) and carry the information to be
shared.Connection can be set between NFC devices
If the amount of information is relatively small (up to
one kilobyte), it is possible to use NFC to transmit
the data itself (e.g. electronic business
cards, contacts).
Speakers (touch to connect)
SmartTags
Application of NFC
•Home computer components • In-car devices
•Home entertainment systems • Headsets and handsets
•Cameras and printers •SecureWLAN modem
set-up
Mobile Ticketing
 A customer books two tickets for a
concert.
 He pays and downloads his tickets
on his mobile phone with a simple
touch.
 He meets with his friend and
transfers the ticket on his mobile.
 They arrive and unlock security
gates thanks to their NFC mobile
phone.
14 millions RFID tickets
were produced by ASK
for Olympic Games in
China - http://www.ask-
rfid.com
 Mobile ticketing will become more popular over the next few
years, with 2.6 billion tickets worth $87 billion, delivered by
2011
Juniper Research (April 2008)
Application of NFC
AdditionalUse Cases for NFC
• Asset Management - Use NFC phones
to read smart tags per product for
inventory
• Access - Ensure secure building area
access for personnel with NFC device
and contactless reader
• Parking – Use NFC to authenticate
parking entry and keep record .
• Meal orders – Customers order their
meals by touching NFC Smart Posters.
• Remote worker reporting – Remote
workers confirm locations visited and
tasks completed
• Maps – An interactive NFC Smart
Poster map allows the user to
download the map, get additional
information on relevant services, and
access coupons, etc.
• Events calendar – Users can
download tickets or coupons or be
linked to event websites

Application of NFC
Some NFC Enabled Devices
Sony Xperia M Nokia Lumia 920 Nokia Lumia 520
LG Nexus 4
NFC Vs Others In Data Rate & Range
Advantages vs Disadvantages
Advantages
• Ease of access
• Quick service
• Mobility
• Variety of use
• Security
Disadvantages
• Short operating
range i.e around 10
cm.
• Slow data rate
• Expensive
• Fare of Hacking
Conclusion
Above all we can say that NFC is one of the best
technologies that we have now. It is growing day by
day and also getting popular.Yes it has some
security problems but the advantages are more
powerful. It does save lots of time.And just by
carrying one device we can avoid carrying multiple
other things….

ACKNOWLEDGEMENT
I have come to know about many things while
completing this seminar topic and I am really
thankful to our respected teachers Mr. Samiran
Mandal and Ms. Joyshree Nath without whose
guidance my seminar would have been
incomplete and imperfect.
