  • 1. NEAR FIELD COMMUNICATION (NFC) BY LOGESH KUMAR. B (logeshkumar@ymail.com)
  • 2. What is NFC NFC is a short-range, high frequency wireless communication technology that enables the exchange of data between devices over about a 10 cm distance. Mainly used for data communication between two mobile devices. 2
  • 3. Evolution of NFC NFC is an extension of Radio frequency identification or RFID technology. Nokia was the first to launch NFC in a mobile phone . Nokia 6131 3
  • 4. How NFC Works NFC is based on RFID technology that uses magnetic field induction to enable communication between electronic devices in close proximity. NFC operates at 13.56 MHz. For two devices to communicate using NFC, one device must have an NFC reader/writer and one must have an NFC tag. The tag is essentially an integrated circuit containing data, connected to an antenna, that can read and written by the reader. 4
  • 5. NFC File Transfer5
  • 6. Comparison With Existing Technologies Aspect NFC RFID Bluetooth Network Stand ard ISO 13157 etc. IEEE 802.15.1 IEEE 802.15.1 Range Upto 10cm < 1 m Upto 30m Frequency 13.56 MHz 13.56 Mhz (varies) 2.4–2.5 GHz Bit rate 424 kbit/s 50kbit/s 2.1 Mbit/s Set-up time < 0.1 s < 0.1 s < 6 s Power consumption < 15mA (read) Same as NFC(15mA) High Connectivity Touch/Tap connect Send/Receive information Configuration needed 6
  • 7. Applications of NFC Used to transfer files between two mobile phone Download music or video from a smart poster 7
  • 8. Applications of NFC Exchange business cards, Pay bus or train or air fare, Parking Tickets, Pay at Kiosks, Pay and purchase at Point of Sale Terminals 8
  • 9. NFC Application in day to day life9
  • 10. Advantages of NFC Very Convenient No manual configuration and settings. No search and pair procedure. Versatility 10
  • 11. Disadvantages of NFC Security Costly Short connectivity range Less data transfer rate (200-412kpbs) 11
  • 12. THANK YOU 12
