NFC allows contactless data transfer between devices within close proximity using radio frequency identification (RFID). It was developed by Nokia, Phillips, and Sony to enable touch-based interactions and communication between objects and devices. NFC works within a range of about 10 cm using magnetic field induction and operates on an unlicensed radio frequency band. It supports various applications including mobile payments, ticketing, access control, and connecting devices by transferring data through touch. While adoption of NFC may take time as payment methods change slowly, it provides a convenient user-friendly interface and compatibility with existing RFID infrastructure.

2. WHAT IS NFC?
Wireless communication technology
Enables data transfer between machines
Uses the concept of Radio Frequency
Identification (RFID)
RFID is a technology that does communication
through radio waves, that exchanges data
between an electronic tag put on an object and a
reader

WIRELESSLY AT A
CLOSE RANGE

4. WHO DEVELOPED NFC AND WHY?
NFC technology was developed by a joint
venture of Nokia, Phillips, and Sony
What NFC can offer:
Touch based
interaction
Objects can
communicate
Objects can
have
memories
Information
as and when
you need it

5. HOW IT WORKS?
NFC works:
Via magnetic field induction technology, and
 operates on an unlicensed radio frequency band
 Works within a range of 10 cm or less and
supports encryption
Requires low power to run
Compatible with contactless Radio Frequency
Identification

6. NFC’S STAGE IN THE HYPE CYCLE
• Gartner’s hype cycle places NFC at the trough
of disillusionment with mainstream adoption
taking 2-5 years
• Reason behind this prediction may be the fact
that payment methods cannot be changed
over night, and users need to be educated
regarding its usage

10. TYPES OF NFC
APPLICATIONS
TOUCH AND GO
• Application such as access control or
transport/event ticketing , where the user
only needs to bring the device storing the
ticket or access code close to the reader
TOUCH AND
CONFIRM
• Application such as mobile payment where
the user has to confirm the interaction by
entering a password or just accepting the
transaction
TOUCH AND
CONNECT
• Links two NFC-enabled devices to enable
transfer of data amongst them, such as
downloading music, exchanging images
etc.

11. PROS AND CONS OF NFC
ADVANTAGES
• Has a wide reach and
availability
• Compatible with existing
RFID infrastructure
• Can be used in various
situations
• User friendly
• Value Added service
DISADVANTAGES
• Security issues can crop up
• Does not cover long
distances

12. FUTURE OF NFC
• Nokia began promoting NFC since 2004
• Philips and Sony are also in line and trying to
bring it in their handsets as well
• Currently, the global membership of NFC in its
forum has exceeded 150 organisations
