Uses and Applications
Project trials and full-scale deployments
Near field communication (NFC) : It is a short-range
communication technology that enables devices to
exchange information with other NFC-enabled devices
or certain NFC supporting cards .
It can be done by touching the devices together or
bringing them into close proximity, usually no more than
a few centimeters.
NFC operates at 13.56 MHz on ISO/IEC 18000-3 air
interface and at rates ranging from 106 kbit/s to 424
NFC traces its roots back to Radio-frequency identification, or
RFID allows a reader to send radio waves to a passive
electronic tag for identification and tracking.
1983 : The first patent to be associated with the
abbreviation RFID was granted to Charles Walton.
2004 : Nokia, Philips and Sony established the Near Field
Communication (NFC) Forum
2006: Nokia 6131 was the first NFC phone .
2011: NFC support becomes part of the Symbian mobile
operating system with the release of Symbian Anna version.
HOW NFC WORK’S
Near-field communication uses magnetic induction between
two loop antennas located within each other's near
field, effectively forming an air-core transformer. It operates
within the globally available and unlicensed radio frequency ISM
band of 13.56 MHz , with a bandwidth of 14KHz .
NFC always involves an initiator and a target .
There are two modes of communication :
Passive communication mode
Active communication mode
PASSIVE COMMUNICATION MODE
The initiator device provides a carrier fields and the
target device answers by modulating the existing field.
In this mode, the target device may draw its operating
power from the initiator-provided electromagnetic
field, thus making the target device a transponder .
ACTIVE COMMUNICATION MODE
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, both devices typically have power supplies.
Passive communication Active communication
COMPARISION OF NFC WITH BLUETOOTH
NFC and Bluetooth are both short-range communication
NFC operates at slower speeds than Bluetooth, but
consumes far less power and doesn’t require pairing.
NFC sets up faster than standard Bluetooth.
The connection between two NFC devices is
automatically established quickly: in less than a tenth of
The maximum data transfer rate of NFC (424 kbit/s) is
slower than that of Bluetooth V2.1 (2.1 Mbit/s).
USES AND APPLICATIONS
There are three main use cases for NFC :
Card emulation : the NFC behaves like an existing
contactless card .
Reader mode : the NFC device is active and read
a passive RFID tag.
P2P mode : two NFC can communicate and

(RESPONSIBLE FOR NFC PROTOCOLS)
NFC is a standard defined by the NFC Forum, a global
consortium of hardware, software / application , credit
card companies ,banking ,network providers , and
others who are interested in the advancement and
standardization of this promising technology.
AT PRESENT THERE ARE AROUND 160

Applications makers will use higher-layer cryptographic
protocols (e.g., SSL) to establish a secure channel.
Application providers and transaction parties, who will
need to use anti-virus and other security solutions to
prevent spyware and malware from infecting systems.
Customers, can also protect their personal devices and
data with passwords, keypad locks, and anti-virus

Market research suggests that over the next few
years, Near Field Communication (NFC) technology will
be in use all around us.
Shipments for NFC enabled phones are forecasted to
reach 700 million units in 2016.
For consumers, the technology will become omnipresent
in our lives, and NFC-enabled mobile phones will
emerge as our primary consumer ID credential.
