Near Field Communication (NFC) Technology

Introduction to NFC

  • NFC is one of the latest wireless communication technologies. As a short-range wireless connectivity technology, NFC offers safe — yet simple and intuitive — communication between electronic devices.
  • Enables the exchange of data between devices over a distance of up to 10 centimeters .
  • NFC-enabled devices can simply point or touch, making application and data usage easy and convenient.
  • The design includes a near-field transmitter and receiver to send data from one device to another

How NFC Works

  • NFC is based on RFID technology that uses magnetic field induction to enable communication between electronic devices in close proximity.
  • NFC operates at 13.56 MHz
  • For two devices (initiator/target) to communicate using NFC, one device must have an NFC reader/writer and one must have an NFC tag.

–The tag is essentially an integrated circuit containing data, connected to an antenna, that can be read and written by the reader.

  • Maximum transfer bit rate of 800kbps.
  • No special software is required.

TYPES OF MODE

USES

EXAMPLES OF USING NFC ENABLED MOBILE PHONES

  • Download music or video from a smart poster.
  • Exchange business cards
  • Pay bus or train or air or taxi fare, etc.
  • Parking Tickets
  • Pay at Kiosks
  • Pay and purchase at Point of Sale Terminals (POST)
  • Access controls in office, hotels, airports, etc.
  • Print receipts to printer

COMPARISON WITH OTHER TECHNOLOGIES

WHAT IS THE FUTURE FOR NFC?

  • Nokia is active in the area of NFC since 2004
  • Together with Philips and Sony, founded the NFC Forum.
  • Currently, global membership in the NFC Forum had exceeded 140 organizations.
