  • 1. NFCNear Field Communication Made By Ashwin Khandelwal
  • 2. What is NFC? It is a set of short-range wireless technologies, typically requiring a distance of 4 cm or less, specifically designed for services such as payment or exchanging small bursts of information. Users of NFC-enabled devices can simply point or touch their devices to other NFC-enabled elements in the environment to communicate with them, making application and data usage easy and convenient.
  • 3. Features Intuitive: NFC interactions require no more than a simple touch. Versatile: NFC is ideally suited to the broadest range of industries, environments, and uses. Technology-enabling: NFC facilitates fast and simple setup of wireless technologies, such as Bluetooth, Wi-Fi, etc.
  • 4. NFC - Technical BasicsWireless Short Range Communication Technology  Based on RFID technology at 1,356 MHz  Operating distance typical up to 10 cm  Compatible with today’s field proven contactless RFID technology  Data exchange rate today up to 424 kilobits/s RFID object 1,356MHz RF Link
  • 5. Functions of NFC Tag Emulation Mode  In this mode the NFC device functions as a non-contact Smart card and acts as Smart card / tag. Reader/Writer Mode  In this case the NFC device acts as an initiator and the passive tag is the target. Peer-to-Peer Mode  In NFC, P2P network can be formed when two computing devices scattered in various locations (near field) are connected to each other. 5

  • 10. NFC Overtaking much of communication device
  • 11. NFC Has Multiple Uses
  • 12. Conclusion In summary, NFC is an efficient technology for communication of short ranges. NFC is based on existing contactless infrastructure around the world that is already in use by millions of people on a daily basis. NFC is not a fashionable nice-to-have technology, but actually a technology that makes people’s life easier.
