NFC allows short-range wireless communication when devices are 4 cm or less apart. It allows users to simply touch their NFC devices to share contact info, access digital content or make payments. NFC provides an intuitive interface and is suited for a wide range of industries and uses, also enabling quick setup of wireless technologies. It operates at 13.56 MHz and can transfer data at up to 424 Kbps, compatible with existing contactless RFID technology. NFC is implemented in phones in integrated, SIM card and memory card forms and is expected to significantly grow its use in communication devices and payments over time.

2. What is NFC?
 It is a set of short-range wireless technologies, typically
requiring a distance of 4 cm or less, specifically designed
for services such as payment or exchanging small bursts of
information.
 Users of NFC-enabled devices can simply point or touch
their devices to other NFC-enabled elements in the
environment to communicate with them, making
application and data usage easy and convenient.

3. Features
 Intuitive: NFC interactions require no more
than a simple touch.
 Versatile: NFC is ideally suited to the broadest
range of industries, environments, and uses.
 Technology-enabling: NFC facilitates fast
and simple setup of wireless technologies, such
as Bluetooth, Wi-Fi, etc.

5. Functions of NFC
 Tag Emulation Mode
 In this mode the NFC device functions as a non-contact Smart card and
acts as Smart card / tag.
 Reader/Writer Mode
 In this case the NFC device acts as an initiator and the passive tag is the
target.
 Peer-to-Peer Mode
 In NFC, P2P network can be formed when two computing devices
scattered in various locations (near field) are connected to each other.

7. NFC In Mobile
3 ways it’s implemented on phones
 Fully Integrated Into The Handset
Ex:The Google Nexus S, Google’s latest flagship phone built in partnership
with Samsung
 On a SIM card
 On a memory card
Ex: Visa introduced a case for the iPhone which contains a microSD card
manufctured by Device Fidelity to bring NFC technology to iPhone users

10. NFC Overtaking much of communication device

11. NFC Has Multiple Uses

12. Conclusion
 In summary, NFC is an efficient technology for
communication of short ranges.
 NFC is based on existing contactless
infrastructure around the world that is already
in use by millions of people on a daily basis.
NFC is not a fashionable nice-to-have
technology, but actually a technology that
makes people’s life easier.
