NFC is a short-range wireless technology that allows data transfer between devices in close proximity. It uses magnetic field induction and works similarly to RFID technology, requiring one device to have an NFC reader/writer and the other to have an NFC tag. NFC allows communication between multiple devices within a small area using the same frequency. It has applications in social networking, payments, and electronic identity documents. While NFC provides advantages over other wireless technologies in some use cases, it also has some disadvantages like a lower data transfer rate and lack of security compared to technologies like Bluetooth.

2. What is NFC
• NFC is a short-range wireless technology.
• NFC provides unique advantages over
other available wireless technologies.
• The design includes a near-field
transmitter and receiver to send data
from one computer to another

3. How NFC Works :
NFC is based on RFID
technology that uses
magnetic field induction
between electronic
devices in close
proximity. For two
devices to communicate
using NFC, one device
must have an NFC
reader/writer and one
must have an NFC tag.

4. Benefits & Features:
• Not restricted to 1-to-1
communication
• Multiple devices in a small area can
communicate with each other using
the same frequency.
• Maximum transfer bit rate of
800kbps.
• No special software is required.
• Operation at a frequency of 13.5
MHz
• No ethical concerns due to range

6. Social networking:
NFC can be used in social networking situations,
such as sharing contacts, photos, videos or
files, and entering multiplayer mobile games.
Application

7. Application
Payment by NFC:
Instant payments and coupon delivery
using your handset, as we do with
your credit card or debit card.

8. Application
Identity documents:
The NFC Forum promotes the potential for NFC-
enabled devices to act as electronic identity
documents and keycards. As NFC has a short range
and supports encryption, it may be more suitable
than earlier, less private RFID systems.
