INTRODUCTION

Near Field Communication at glance.

What is NFC ?

NFC or Near Field Communication is a set of standards or protocols to communicate

between two devices by either touching or bringing into close proximity ( less than 4

cm ).

The communicating protocols of such devices are based on RFID Standards, including

ISO 14443. These standards are defined and extended by the NFC Forum, which was

founded on 2004 by some major companies such as Sony, Nokia, Philips, Samsung etc.

The operating Frequency of such communication is merely 13.56 MHz ( +/- 7 ) which is

very low. This gives an advantage of easily integrating into portable devices without the

need of much battery power.
