What is NFC?

It is a set of short-range wireless technologies, typically requiring a distance of 4 cm or less, specifically designed for services such as payment or exchanging small bursts of information.

Users of NFC-enabled devices can simply point or touch their devices to other NFC-enabled elements in the environment to communicate with them, making application and data usage easy and convenient.

Features

Intuitive: NFC interactions require no more than a simple touch.

Versatile: NFC is ideally suited to the broadest range of industries, environments, and uses.

Technology-enabling: NFC facilitates fast and simple setup of wireless technologies, such as Bluetooth, Wi-Fi, etc.

NFC - Technical Basics

Wireless Short Range Communication Technology Based on RFID technology at 1,356 MHz Operating distance typical up to 10 cm Compatible with today’s field proven contactless RFID

technology Data exchange rate today up to 424 kilobits/s

Functions of NFC Tag Emulation Mode

In this mode the NFC device functions as a non-contact Smart card and acts as Smart card / tag.

Reader/Writer Mode In this case the NFC device acts as an initiator and the passive tag is the

target. Peer-to-Peer Mode

In NFC, P2P network can be formed when two computing devices scattered in various locations (near field) are connected to each other.
