Transcript of "New microsoft office power point presentation [autosaved]"

  1. 1. NEAR FIELD COMMUNICATION PRESENTED BY MEGHAN SATHE
  2. 2. OVERVIEW AIM & INRODUCTION TO NFC  FEATURES  OPERATION  MODES OF NFC  APPLICATIONS  SECURITY ASPECTS  COMPARISON  CONCLUSION 
  3. 3. AIM-TO DISCUSS THE NFC TECHNOLOGY AND ITS APPLICATIONS  SHORT RANGE HIGH FREQ WIRELESS TECHNOLOGY  EXTENSION OF RFID  MAINLY AIMED FOR HANDHELD DEVICES
  4. 4. FEATURES  SIMPLIFIED TRANSACTIONS,DATA EXCHANGE & WIRELESS COMN  CONNECTION IS EST UPTO A DISTANCE OF 10-20 CM(OR TOUCH)  USED FOR TRACKING AND IDENTIFICATION  OPERATES AT 13.56  MHZ & RATES RANGING FROM 106 KBIT/S TO 424 KBIT/S  SUPPORTED DATA RATES: 106, 212 OR 424 KBIT/S
  5. 5. COMPARISON WITH EXISTING TECHNOLOGY
  6. 6. OPERATION  WORKS WITH TWO TERMINALS INITIATOR  TARGET  INITIATOR TARGET
  7. 7. OPERATION
  8. 8. OPERATION COMMUNICATEs VIA MAGNETIC FIELD INDUCTION, WHERE TWO LOOP ANTENNAS ARE LOCATED WITHIN EACH OTHER'S NEAR FIELD  THE READER CONTINUOUSLY GENERATES AN RF CARRIER SINE WAVE (AT 13.56 MHZ)  DETECTED MODULATION OF THE FIELD WOULD INDICATE THE PRESENCE OF A TAG. 
  9. 9. MODES OF NFC PASSIVE MODE  ONLY ONE ACTIVE DEVICE  INITIATOR PROVIDES CARRIER FIELD & TARGET ANSWERS  ACTIVE MODE  BOTH DEVICES ARE ACTIVE  BOTH DEVICES PRODUCE ELECTROMAGNETIC FIELDS 
  10. 10. MODES OF NFC ACTIVE MODE PASSIVE MODE
  11. 11. USAGE OF NFC
  12. 12. CARD EMULATION MODE  NFC DEVICE BEHAVES AS A CONTACTLESS SMART CARD  THE EXTERNAL CARD READER ACCESSES THE SECURE ELEMENTS OF THE DEVICE  ENABLES CONTACTLESS PAYMENTS AND TICKETING BY NFC ENABLED PHONES
  13. 13. PEER TO PEER MODE  TWO NFC ENABLED DEVICES CAN EXCHANGE DATA  BOTH DEVICES TAKE PART IN THE COMMUNICATION  SHARING BLUETOOTH OR WI-FI LINK SET-UP PARAMETERS OR EXCHANGING DATA SUCH AS VIRTUAL BUSINESS CARDS OR DIGITAL PHOTOS
  14. 14. READ/WRITE MODE  NFC DEVICE IS CAPABLE OF READING NFC FORUM-MANDATED TAG  DEVICE READS AND ACTS ACCORDINGLY WHAT IS WRITTEN IN THE TAG  SMART POSTERS ARE AN EXAMPLE
  15. 15. APPLICATIONS  COMMERCE  SOCIAL N/W  SMARTPHONE AUTOMATION  ANDROID BEAM  GOOGLE WALLET
  16. 16. SECURITY ASPECTS  EAVESDROPPING  DATA MODIFICATION  LOST PROPERTY
  17. 17. COMPARISON ADVANTAGES DISADVANTAGES CONVINIENCE  VERSATALITY   VERY SHORT RANGE  LOW DATA TRANSFER RATE   HIGH INITIAL COST SECURE  EASY SETUP  ECONOMICAL
  18. 18. CONCLUSION  PRIMARY TARGETS-MOBILE PHONES  NFC WILL SOON TAKEOVER ALL HANDHELD DEVICES  COMBINING NFC WITH OTHER COMN TECHNOLOGIES WILL INCREASE ITS RANGE OF APPLICATIONS
  19. 19. THANK YOU
