Introduction to NFC
• NFC is one of the latest wireless communication technologies. As a
short-range wireless connectivity technology, NFC offers safe — yet
simple and intuitive — communication between electronic devices.
• Enables the exchange of data between devices over a distance of up to
20 centimeters (4 cm Practically). But with the software
implementation techniques, you probably have to touch the devices.
• NFC-enabled devices can simply point or touch, making application and
data usage easy and convenient.
• The design includes a near-field transmitter and receiver to send data
from one device to another
How NFC 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 (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.
• Maximum transfer bit rate of 800kbps.
• No special software is required.
TYPES OF MODE
Passive Mode Active Mode
The initiator device provides a carrier
fields and the target device answers by
modulating the existing field.
Both initiator and target device
communicate by alternately generating
their own fields.
A device deactivates its RF field while it is
waiting for data.
In this mode, the target device may draw
its operating power from the initiator-
provided electromagnetic field.
In this mode, both devices typically have
1983 The first patent to be associated with the abbreviation RFID was granted to Charles
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
2009 In January, NFC Forum released Peer-to-Peer standards to transfer contact, URL,
initiate Bluetooth, etc.
2010 Samsung Nexus S: First Android NFC phone shown
2011 Google I/O "How to NFC" demonstrates NFC to initiate a game and to share a contact,
URL, app, video, etc.
2011 NFC support becomes part of the Symbian mobile operating system with the release
of Symbian Anna version
2011 RIM is the first company for its devices is certified by MasterCard Worldwide, the
functionality of PayPass
2014 Apple introduced Apple Pay for NFC-enabled mobile payment on iPhone 6, iPhone 6
Plus, and the Apple Watch when Apple releases it in early 2015.
• NFC devices can be used in contactless payment systems, similar to those currently
used in credit cards and electronic ticket smartcards, and allow mobile payment to
replace or supplement these systems.
• For example, Google Wallet allows consumers to store credit card information in a
virtual wallet and then use an NFC-enabled device at terminals that also
accept MasterCard PayPass transactions. Germany, Austria and Latvia have trailed
NFC ticketing systems for public transport. And China is using it all over the country
in public bus transport.
• NFC offers a low-speed connection with extremely simple setup, and could be used
to bootstrap more capable wireless connections. It could, for example, replace the
pairing step of establishing Bluetooth connections or the configuration of Wi-
• NFC can be used in social networking situations, such as sharing contacts, photos,
videos or files, and entering multiplayer mobile games.
• The NFC Forum promotes the potential for NFC-enabled devices to act as
electronic identity documents and keycards. As NFC has a short range and
supports encryption, it may be more suitable than earlier, less private RFID
EXAMPLES OF USING NFC ENABLED
• Download music or video from a smart poster.
• Exchange business cards
• Pay bus or train or air or taxi fare, etc.
• Parking Tickets
• Pay at Kiosks
• Pay and purchase at Point of Sale Terminals (POST)
• Access controls in office, hotels, airports, etc.
• Print receipts to printer 8
WHAT IS THE FUTURE?
• Nokia is active in the area of NFC since 2004
• Together with Philips and Sony, founded the NFC Forum.
• Currently, global membership in the NFC Forum had exceeded
