2. What is NFC?
 Short Range Wireless Technology.
 Provides unique advantages over other Wireless
Technologies.
 Offers safe&intuitive communication

3. ◦ Easy to use wireless communication interface
for the last few centimeters
◦ Easy to use target selection, by simply holding
two devices close to each other
 NFC is as easy as….

4.  Wireless Short Range Communication Technology
 Based on RFID technology at 13,56 MHz
 Operating distance typical up to 10 cm
 Compatible with today’s field proven contactless RFID
technology
 Data exchange rate today up to 424 kilobits/s
RFID object
13,56MHz RF Link

5. NFC Block Diagram

 DCE-DCE serial cable

7. Features
 Not restricted to 1 to 1 comm.
 Multiple devices can communicate with each other
using same frequency at 13.56MHz @ 106kb/s to
848kb/s
 No special software is required.
 Peer to Peer communication is possible.
 Requires log power than Bluetooth.
 Good choice for secure transactions contactless credit
card payments

8. APPLICATIONS

Mobile payment
Bluetooth pairing
Merchant card system
Peer-peer system
Application
software(mobile client)

9. Advantages
 No interference due to decaying fields
 Allows communication both
between two powered and passive devices
 Convenient usage by simply holding the
two devices close to each other

10. Disadvantages
 Data transfer rate is small compared to
blue
tooth and other wireless communications
 No protection in eavesdropping
 No protection in data modification

11. Conclusion
 Providing secure channel will avoid the draw
backs such as evesdropping or data modification.
 NFC is compatible with existing RFID
infrastructures.
 NFC is an efficient technology for communications
with short ranges
