Near Field Communication

  1. 1. Brian MaassISLT 9410 Emerging Technologies Slideshare version (No animations/photos)
  2. 2.  A technology related to RFID that allows wireless data transfer between devices, or between a device and a tag. Embedded in Tags Laptops Phones  Embedded  MicroSD add-on
  3. 3.  Information links (like QR codes), Social media check-ins, Smart posters Peer-to-peer transfers – photos, contact info, files
  4. 4.  Access – doors, computers, car ignitions, Public transportation, event ticketing Quick set-up of other services – Wi-Fi or Bluetooth pairing Mobile paymentsMissouri State has selected an NFC system to replace magnetic strip cards for campus IDs
  5. 5.  13.56 MHz Low power. Operates at close proximity only – up to 10 cm, but in practice averages 4 cm max Can be read-only or read-write. One-way or two-way communication. Only one side of the connection needs to be powered. Other side uses induction (like wireless charging) Can store/exchange up to 1MB of data Tags currently run approximately $0.50 each
  6. 6.  Fast connection Simple to use Low power consumption Shorter distance than RFID means more security Exchanges data in two directions (RFID is one way) Compatible with some existing RFID tags Faster set-up than Wi-Fi or Bluetooth Can be used to speed up their connection process
  7. 7.  NFC Tags can hold up  QR codes hold 7,089 to 1MB of data characters NFC can be passive or  QR codes are passive active – Allows two- only – One-way data way exchange of data  QR codes are NFC tags can be ugly/jarring embedded in anything  QR codes can currently (unobtrusive) be read by most phones, Active NFC currently but user must open app limited to certain and scan the code phones
  8. 8. FOR AGAINST Verifone (dominant maker of point-of-sale hardware)  PayPal/eBay Phones makers – Samsung,  Square Nokia, Blackberry, HTC  Retalix Google Wallet and Nexus ISIS – AT&T, Verizon, and UNDECIDED T-Mobile Visa/Mastercard  Apple Bank of America/Citibank Gaming – Angry Birds and Fruit Ninja Objecs – NFC gravestones
  9. 9.  Library card replacement Payments Reservations One touch setup of Wi-Fi access Self checkout -  Near term - Powered NFC checkout device – tap card, tap book, walk out  As more patrons have NFC phones – tap phone to book, walk out
  10. 10.  Information tags on books/media  Bibliographic info  Reviews  Author info  “You might also like” Information tags on displays/signs  “More info on this subject” tag  Related books/materials in this library  Instant e-book download from poster/display
  11. 11.  Security and Privacy  Concern about spoofing tags, snooping on data exchange, activating tags at greater distances  Can be Pin number protected  Can be encrypted  Can be shut down remotely  Critical data can be kept on separate secure chip in phone MasterCard has said it is as secure as any credit/debit card.
  12. 12.  Digital divide  We could still issue the NFC-enabled library cards to provide much of this functionality to users without mobile phones  Mobile phones are becoming ubiquitous  6 billion phones in the world  Some countries over 100% mobile phone penetration 
