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) 2.42.5 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 13. Questions ??? 13
