Presentation Transcript

  1. Near Field Communication • Tyler Swofford • Matthew Kotan

  2. Outline • What is Near Field Communication (NFC) • How does it work • Current applications for NFC • Key Companies • Security Concerns

  3. What is NFC • NFC is a transmission protocol • It is designed for short range communication • It is based on Radio Frequency Identification (RFID) • Unlike RFID it features two way communication • In addition communication is limited to being between two devices

  4. How Does it Work • NFC devices use inductive coupling to generate radio signals • These radio signals are then used to transport information • NFC devices can be either active or passive • Active devices have their own power source • Passive devices rely on active devices to function

  5. Current Applications • Data Exchange between mobile devices • Simplify blue tooth pairing • Wifi Authentication • Can be used with Credit Cards as an alternative to magnetic strips • Key for digital locks

  6. Current Applications • Improved Advertising with Smart Posters • Pay parking meters using NFC enabled phones • The Museum of London allows users with NFC enabled phones at exhibits to gain more information • Samsung Tec Tiles offer interesting possibilities for daily task automation

  7. Key Companies • Multiple Big Players in this technology • EBAY has PayPal • AT&T, T-Mobile and Verizon have ISIS • Google has Google Wallet

  8. Security Concerns • Interception attacks • Man in the middle attacks • Eavesdropping • Data corruption and manipulation • Theft

  9. Conclusion • NFC is a short distance radio transmission protocol • It can be used to simplify many daily tasks • Security is a large concern particularly man in the middle attacks • Financial applications likely won't catch on until security issues have been addressed
