2. What is NFC?
•NFC is a short-range wireless technology.
• NFC is based on Radio Frequency Identification (RFID)
technology.
•Communication is also possible between an NFC device
and an unpowered NFC chip, called a "tag“.

3. OPERTAION MODES OF NFC
MODES OF
OPERATION
PASSIVE ACTIVE
MODE MODE

4. Active mode
 In Active mode, both devices with NFC chip generates an
electromagnetic field and exchange data.
Two NFC
enabled
devices
transfer-
ring data
in active
mode

5. Passive mode
 In Passive mode, there is only one active device and the
other uses the tag to exchange information.
A NFC-
enabled
mobile
phone is
paired
with a
RFID-
tagged
"smart

9. COMPARISON WITH BLUETOOTH
Bluetooth NFC
Range 0 ~ 10 m < 50 cm
Transfer rate Medium Low
1 Mbps 424 kbps
Security High Very High
Cost Medium Very Low

10. ADVANTAGES
•No special software.
•No manual configuration and settings.
Disadvantages
•Short range communication.
•The data transfer rate is very less.

11. Conclusion
Mobile handsets are the primary target for
NFC and soon NFC will be implemented
in most handheld devices.
