NFC

NFC technology is intended mainly for use in mobile phones. There are currently three specific uses for NFC:

* Card emulation: the NFC device behaves like an existing contactless card
* Reader mode: the NFC device is active and reads a passive RFID tag, for example for interactive advertising
* P2P mode: two NFC devices communicating together and exchanging information.

Plenty of applications are possible, such as:

* Mobile ticketing in public transport: an extension of the existing contactless infrastructure, such as Mobile Phone Boarding Pass.[2]
* Mobile payment: the device acts as a debit/credit payment card.
* Smart poster: the mobile phone is used to read RFID tags on outdoor billboards.
* Bluetooth pairing: in the future pairing of Bluetooth 2.1 devices with NFC support will be as easy as bringing them close together and accepting the pairing. The process of activating Bluetooth on both sides, searching, waiting, pairing and authorization will be replaced by a simply bringing the mobile phones close to each other.

Other applications in the future could include:

* Electronic ticketing: airline tickets,[2] concert/event tickets, and others
* Electronic money
* Travel cards
* Identity documents
* Mobile commerce
* Electronic keys: replacements for physical car keys, house/office keys, hotel room keys, etc.
* NFC can be used to configure and initiate other wireless network connections such as Bluetooth, Wi-Fi or Ultra-wideband.

Near Field Communication, or more commonly known as NFC, is a subset of RFID that limits the range of communication to within 10 centimeters or 4 inches.
For RFID, Malicious people can receive your information and clone it into another tag and use it for themselves. This is where NFC comes in.

1.NFC is just an extension to RFID technology
2.RFID is capable of accepting and transmitting beyond a few meters while NFC is restricted to within 4 inches
3.RFID has a wide range of uses while NFC is usually used in cases where security is needed
