NEAR FIELD COMMUNICATION (NFC)

Presented by :- NITISH TANWAR

What is NFC ? It stands for Near Field Communication. It is a short range, high frequency, low bandwidth and wireless

communication technology between two device over about 10 cm.

It is based on RFID Technology. It allows users to seamlessly share content between digital

devices, pay bills wirelessly or even use their cellphone as an electronic traveling ticket on existing contactless infrastructure already in use for public transportation.

HISTORY2002- Sony and Philips agreed on establishing a

new technology specification and created a technical outline on March 25, 2002.

2004-Nokia, Philips and Sony established the Near Field Communication (NFC) Forum.

2006- Initial specifications for NFC Tags.2006- Nokia 6131 was the first NFC phone.2010- Samsung Nexus S: First Android NFC phone.2011- Google I/O "How to NFC" demonstrates NFC

to initiate a game and to share a contact, URL, app, video, etc.

2013 Samsung and Visa announce major partnership to develop mobile payments.

Working Principle • NFC work on the principle of RFID (Radio

Frequency Identification).• Types of coupling in RFID:

Backscatter couplingCapacitive couplingInductive coupling

Operation of nfc

• It is based on inductive coupling• NFC works using magnetic induction between two

antennas located within each others near field

MODES OF OPERATION

PASSIVE MODE

ACTIVE MODE

In Active mode, both devices with NFC chip generates an electromagnetic field and exchange data.

ACTIVE MODE

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

PASSIVE MODE

Applications of NFC

• NFC applications can be split into the following three basic categories:

Touch and GoTouch and ConfirmTouch and Connect

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

Applications such as mobile payment where the user has to confirm the interaction by entering a password or just accepting the transaction.

Touch and Confirm

Linking two NFC-enabled devices to enable peer to peer transfer of data such as downloading music, exchanging images or synchronizing address books.

Touch and Connect

Using NFC to Pay for Parking Using an NFC-enabled Phone to Exit a London Train Station

A Bus Rider in China Uses Her Phone to Redeem Her Pass

Using an NFC-enabled Phone for Transport Entry in Japan

“Touch and Travel” with an NFC-enabled Phone in Germany

Comparison with Existing Technology

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.

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.

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.

Future of NFC in India

• Chennai metro plans to including an NFC ticketing option when its service launch in 2015

• Madhya Pradesh Tourism Development Corporation is to use NFC to provide tourists with information at heritage site

• PVR cinema have implemented an NFC payment service

• Mahindra opens NFC test lab in Bangalore
