2. What is NFC ?
• NFC is a short range wireless technology that allows
communications to take place between devices that
either touch or are momentarily held close together

3. Specification and Importance
• Distance of 10 cm or less
• Operates at 13.56 MHz on ISO/IEC 18000-3 air
interface and at rates ranging from 106 Kbit/s to
424 Kbit/s
• Requires low power
• Compatible with contactless RFID technology

4. Communication Modes
Device A Device B Description
Active Active When a device sends, it generates an RF field.
When waiting for data, a device doesn’t generate
an RF field. Thus, the RF field is alternately
generated by Device A and Device B.
Active Passive The RF field is generated by Device A only.
Passive Active The RF field is generated by Device B only.

8. Potential Security Threats

9. The Solution

10. The Solution (Cont.)
• Establishing a secure channel between two NFC
devices is the best approach to protect against
eavesdropping and any kind of data modification
attack.
• The NFC Specific
Key Agreement

11. Future Prospects
• Vehicle Ignition
A NFC enabled vehicle can be unlocked and started just
by tapping the user’s NFC device onto the vehicle
removing the need of carrying a pair of keys. It can even
be used to communicate between the device and the
vehicle and monitor the vehicle’s health through some
specific app
• Unlock Door
Smart keyless doors can be made by implementing NFC
technology onto doors, where a single tap of the device
onto the door would unlock it eradicating the pain of
inserting the key and unlocking it.

12. Latest news about NFC
• Google is working with Citigroup and MasterCard on
NFC mobile payment solution
• Airlines move closer to NFC tech for passengers- NFC
allows a Smartphone to be used to "tap and check-in"
or "tap and board" their flight
• Nintendo's Wii successor, the Wii U, will come equipped
with near-field communication (NFC) technology
• Nokia went on record to say that all future Symbian
devices will have built-in NFC support, a de-facto
feature
• Recently “Ra.One” became the first Indian movie to be
marketed through NFC

13. Conclusion
 NFC has the potential to be a disruptive
technology, changing the way that lives are
lived, transforming everyday tasks, making
things easier, more intuitive and more effective
 A significant advantage of this technique is the
compatibility with existing RFID infrastructures.
Additionally it would bring benefits to the setup
of longer-range wireless techniques such as
Bluetooth
 Though security concerns are present, they can
be overcome through the use of various
schemes such as setting up a secure channel,
combined with which NFC can provide
confidentiality, integrity and authenticity
