  2. 2. Introduction Communication – Now & Before :  Communication is the activity of sharing any kind of information..  Over the years we are surrounded by technologies like mobile, internet, computer etc..  Scientists are trying to combine communication with technology..
  3. 3. What is Near Field Communication  Near Field Communication (NFC) is a new short-range, standards-based wireless connectivity technology, that uses magnetic field induction to enable communication between electronic devices in close proximity.  It is mainly aimed for Handheld devices like Smartphone and similar devices.  It is based on RFID [Radio-frequency identification]
  4. 4. What is RFID:  Radio-frequency identification (RFID) is the wireless non-contact use of radio-frequency electromagnetic fields to transfer data  Its purpose is to automatically identify and track tags attached to objects.  The tags contain electronically stored information.
  5. 5. Quick history 1983 • The first patent to be associated with the abbreviation RFID was granted to CharlesWalton. 2004 • Nokia, Philips and Sony established the Near Field Communication (NFC) Forum. 2011 • First mobile phone( Nokia 6131) with NFC released by NOKIA. 2010 • Samsung Nexus S: First Android NFC phone. 2011 • NFC support becomes part of the Symbian mobile operating system and Blackberry OS.

  7. 7. Working Principles and Features  NFC is an extension of Radio frequency identification (RFID) technology that combines the interface of a smartcard and a reader into a single device.  This allows two-way communication between endpoints, where the earlier systems were one-way only.  For two devices to communicate using NFC, one device must have an NFC reader/writer and one must have an NFC tag  It allows for simplified transactions, data exchange, and wireless connections between two devices
  8. 8. Working Principles and Features  A radio communication is established by touching the two phones or keeping them in a proximity of a few centimetres (up to 10 cm) .  Supported data rates: 106, 212 and 424 Kbit/s  NFC use an initiator and a target.The initiator actively generates an RF field that can power a passive target.  Allows communication between o Two powered (active) devices o Powered and non self-powered (passive) devices
  9. 9. Modes of Operation 1. Card Emulator Mode (Passive Mode) : This mode emulates a traditional smart card (such as Mastercard or Visa) and makes this mode convenient because of the already existing setup for the contactless payments by these smartcards companies.Thus NFC enabled mobile phones becomes a credit card.
  10. 10. Modes of Operation 2. Peer to Peer (P2P) Mode: P2P offers interaction between two active NFC-equipped devices such as phones. Like Using this mode, one could make payments to another individual or business just by tapping the two phones together
  11. 11. Modes of Operation 3. Reader Mode : This allows the phone to read passive RFID tags on posters, stickers. For instance, one could tap his phone on the reader tag in a movie poster and it would begin playing the movie trailer, provide theatre times, locations, and so on.
  12. 12. Application of NFC
  13. 13. Smart Posters  An object that has, affixed to or embedded in it, one or more readable NFC tags with NDEF messages stored in them.  Each tag is read when an NFC device is held close to it  Location wise information  Trailers &Tickets booking  Billboard, garment tag, magazine page, even a three-dimensional object Application of NFC
  14. 14. NFC and Mobile Payment A customer makes his payment through mobile phone using NFC  NFC phone will open wallet application  At check out, wallet will display all credit/debit cards in wallet for payment  Customer will select card for payment  Wallet will show the confirmation page with the check out basket  Wallet will connect to retailer back end for authorization and display tracking information Application of NFC
  15. 15. Peer-to-peer Connection Handover : A handover use case is the exchange of configuration information via the NFC link to easily establish a connection over (for e.g. Bluetooth or Wi-Fi ) and carry the information to be shared.Connection can be set between NFC devices If the amount of information is relatively small (up to one kilobyte), it is possible to use NFC to transmit the data itself (e.g. electronic business cards, contacts). Speakers (touch to connect) SmartTags Application of NFC •Home computer components • In-car devices •Home entertainment systems • Headsets and handsets •Cameras and printers •SecureWLAN modem set-up
  16. 16. Mobile Ticketing  A customer books two tickets for a concert.  He pays and downloads his tickets on his mobile phone with a simple touch.  He meets with his friend and transfers the ticket on his mobile.  They arrive and unlock security gates thanks to their NFC mobile phone. 14 millions RFID tickets were produced by ASK for Olympic Games in China - http://www.ask- rfid.com  Mobile ticketing will become more popular over the next few years, with 2.6 billion tickets worth $87 billion, delivered by 2011 Juniper Research (April 2008) Application of NFC
  17. 17. AdditionalUse Cases for NFC • Asset Management - Use NFC phones to read smart tags per product for inventory • Access - Ensure secure building area access for personnel with NFC device and contactless reader • Parking – Use NFC to authenticate parking entry and keep record . • Meal orders – Customers order their meals by touching NFC Smart Posters. • Remote worker reporting – Remote workers confirm locations visited and tasks completed • Maps – An interactive NFC Smart Poster map allows the user to download the map, get additional information on relevant services, and access coupons, etc. • Events calendar – Users can download tickets or coupons or be linked to event websites NFC Parking >> << Security Gate Application of NFC
  18. 18. Some NFC Enabled Devices Sony Xperia M Nokia Lumia 920 Nokia Lumia 520 LG Nexus 4
  19. 19. NFC Vs Others In Data Rate & Range
  20. 20. Advantages vs Disadvantages Advantages • Ease of access • Quick service • Mobility • Variety of use • Security Disadvantages • Short operating range i.e around 10 cm. • Slow data rate • Expensive • Fare of Hacking
  21. 21. Conclusion Above all we can say that NFC is one of the best technologies that we have now. It is growing day by day and also getting popular.Yes it has some security problems but the advantages are more powerful. It does save lots of time.And just by carrying one device we can avoid carrying multiple other things…. References •www.google.com •En.wikipedia.org •www.slideshare.net •nfc-forum.org
  22. 22. ACKNOWLEDGEMENT I have come to know about many things while completing this seminar topic and I am really thankful to our respected teachers Mr. Samiran Mandal and Ms. Joyshree Nath without whose guidance my seminar would have been incomplete and imperfect.
