Introduction to NFC


Published on

NFC, short for Near Field Communication, is a short range wireless RFID technology that makes use of interacting electromagnetic radio fields instead of the typical direct radio transmissions used by technologies such as Bluetooth. It is meant for applications where a physical touch, or close to it, is required in order to maintain security. NFC is planned for use in mobile phones for, among other things, payment, in conjunction with an electronic wallet

Introduction to NFC

  1. 1. Introduction toNear Field Communication(NFC)Venkat Updated: 7th April 2013
  2. 2. NearFieldCommunication • Near field communication (NFC), is amethod of contactless communicationbetween two NFC enabled devices(Smartphone, tablets etc.)• NFC forum ensures strict standards to NFCdevice manufactures to makecommunication secured and easy• NFC operates in two modes– Active mode : Can read/send data from/to otherNFC enabled device– Passive mode : Can not read data from otherdevice (SmartPosters)• NFC is based on RFID technology– Magnetic field induction technology– Operates on Unlicensed Frequency• Specification– Works from touching distance to 4cms (Somedevices up to 10cms)
  3. 3. History • In 2004 Nokia, Philips and Sony jointlyestablished the NFC forum• In 2006, NFC tags specification released• In 2006, Nokia released first NFC enabledmobile (Nokia 6131)• In 2009, NFC forum released Peer-to-Perstandards to exchange contact, URL etc.• In 2010 Samsung releases Nexus S withNFC capability (Android)• In 2010, city of Nice in South Franceenables some of the services liketransportation, tourism and student servicesusing NFC• In 2011, RIM was certified by MasterCardworldwide to use NFC for transaction(PayPass)• In 2011, Google demonstrated GoogleSource:

  13. 13. Conclusion • Every Smartphone companies and deviceOS developers are working to support NFCin all their devices• It is expected that the gross transactionvalue using NFC is going to exceed $75billion by 2013• NFC is a powerful technology that willchange our way of life in froth coming years• NFC enabled device is going to be a featurewallet
