Transcript of "near field communication"

  1. 1. NEAR FIELD COMMUNICATION PREPARED BY: CHITRA BENGANI (12417)
  2. 2. WHAT IS NFC? Wireless communication technology Enables data transfer between machines Uses the concept of Radio Frequency Identification (RFID) RFID is a technology that does communication through radio waves, that exchanges data between an electronic tag put on an object and a reader
  3. 3. IN SIMPLE WORDS… A WAY BY WHICH DEVICES CAN SEND AND RECEIVE INFORMATION WIRELESSLY AT A CLOSE RANGE
  4. 4. WHO DEVELOPED NFC AND WHY? NFC technology was developed by a joint venture of Nokia, Phillips, and Sony What NFC can offer: Touch based interaction Objects can communicate Objects can have memories Information as and when you need it
  5. 5. HOW IT WORKS? NFC works: Via magnetic field induction technology, and  operates on an unlicensed radio frequency band  Works within a range of 10 cm or less and supports encryption Requires low power to run Compatible with contactless Radio Frequency Identification
  6. 6. NFC’S STAGE IN THE HYPE CYCLE • Gartner’s hype cycle places NFC at the trough of disillusionment with mainstream adoption taking 2-5 years • Reason behind this prediction may be the fact that payment methods cannot be changed over night, and users need to be educated regarding its usage
  7. 7. MODES OF OPERATION MODES OF OPERATION ACTIVE MODE PASSIVE MODE
  8. 8. COMMUNICATION WAYS DEVICE 1 DEVICE 2 EXPLANATION ACTIVE PASSIVE The Radio Frequency field is generated by Device 1 only. PASSIVE ACTIVE The Radio Frequency field is generated by Device 2 only. ACTIVE ACTIVE When either of the devices are sending data then they are generating Radio Frequency fields alternately.
  9. 9. APPLICATION OF NFC NFC APPLICATIONS TOUCH AND GO TOUCH AND CONFIRM TOUCH AND CONNECT
  10. 10. TYPES OF NFC APPLICATIONS TOUCH AND GO • Application such as access control or transport/event ticketing , where the user only needs to bring the device storing the ticket or access code close to the reader TOUCH AND CONFIRM • Application such as mobile payment where the user has to confirm the interaction by entering a password or just accepting the transaction TOUCH AND CONNECT • Links two NFC-enabled devices to enable transfer of data amongst them, such as downloading music, exchanging images etc.
  11. 11. PROS AND CONS OF NFC ADVANTAGES • Has a wide reach and availability • Compatible with existing RFID infrastructure • Can be used in various situations • User friendly • Value Added service DISADVANTAGES • Security issues can crop up • Does not cover long distances
  12. 12. FUTURE OF NFC • Nokia began promoting NFC since 2004 • Philips and Sony are also in line and trying to bring it in their handsets as well • Currently, the global membership of NFC in its forum has exceeded 150 organisations
  13. 13. SWOT ANALYSIS STRENGTHS • • • • • • Liquidity Mobile Time Saver Light Security Interactive WEAKNESSES • • • • • Fragile Exhaustible Cyber breach Identity theft Untraditional NFC OPPORTUNITES • • • • • • New markets Interactive Marketing Cell carriers E-wallet New and improved security measures Personalised fair information practices THREATS • • • • • Laws and regulations Consumer privacy and data security Consumer freedom Payment data scraping Limit phone usage
