ABSTRACT Near Field Communication (NFC) is based on a short- range wireless connectivity, designed for intuitive, simple and safe interaction between electronic devices. It is a easy to use wireless communication interface for last few centimeters. It is easy to use target selection by simply holding two devices close to each other. NFC IS AS EASY AS A TOUCH

INTRODUCTION In our daily life NFC will be the contact-less interface that allows people to do intentional interaction with their smart and connected environment in the most convenient way. WHAT IS NFC? NFC stands for Near Field Communication. It is a wireless communication technology based upon MHz RF-ID. It is designed for read/write transactions with a very short range operating distances up to a few centimeters.

WORKING. Near-field communications (NFC) combines two established technologies: radio frequency identification (RFID) tags, which are tiny chips with built-in radios and wireless reader that picks up the signals from the radios. The reader when activated emits a short range radio.signal that powers up a microchip on the tag, and allows for reading a small amount of data that can be stored on the tag Two communication modes at different transfer speeds are possible for NFC device. Active mode Passive mode

Active mode: In active mode both initiator and target are using their own generated RF field to enable the communication. In active mode the data is sent using amplitude shift keying (ASK). This means the base RF signal (13, 56 MHz) is modulated with the data according to a coding scheme.

Passive mode: In passive NFC mode, the target answers to an initiator in load modulation scheme. The initiator generates the RF field. Passive mode the data is sent using a weak load modulation. This difference in the modulation strength is very important from a security point of view as we will describe later on in the security analysis.

TECHNICAL BASIS AND FEATURES  It is intuitive (“touch and start”)  It is suitable for payment/financial applications  It interacts also with battery-less smart devices  It is low cost  Standardized in ISO/IEC NFCIP-1 (NFC Interface and Protocol - 1)  Based on RF-ID technology at 13,56 MHz  Operating distance typical 10 cm  Data rate today up to 424 kbps (up to 1 Mbps planned)

APPLICATIONS NFC applications can be split into the following four basic categories:  Touch and Go: Applications such as access control or transport/event ticketing, where the user needs only to bring the device storing the ticket or access code close to the reader. Also, for simple data capture applications, such as picking up an Internet URL from a smart label on a poster.  Touch and Confirm: Applications such as mobile payment where the user has to confirm the interaction by entering a password or just accepting the transaction.  Touch and Connect: Linking two NFC-enabled devices to enable peer to peer transfer of data such as downloading music, exchanging images or synchronizing address books.  Touch and Explore: NFC devices may offer more than one possible function. The consumer will be able to explore a device's capabilities to find out which functionalities and services are offered.

ADVANTAGES Low cost, NFC has very fast and easy configuration and pairing.Instant connection capability. “Out of the box” - No special software - No manual configuration and settings - No search and pair procedure Intuitive - User initiates the process - Simple data acquisition just by touching High level of flexibility and adaptability - Read data from any electrical device (interface dependent) - Read data from passive RFID tag

CONCLUSION In the near future NFC will be the frontrunner technology for data capture, data transfer and access control applications. NFC technology continues to evolve and develop new applications. It is going to bring revolution in mobile communications. Consultants will continue to pitch the blue-sky potential of the technology.There will be a significant spike in NFC activities in future.
