- 1. Near Field Communication (NFC) By: Vivek Prasad ¾ B.Tech(CSE), GIT B1 - 65
- 2. What is NFC ? • NFC is a short range wireless technology that allows communications to take place between devices that either touch or are momentarily held close together
- 3. Specification and Importance • Distance of 10 cm or less • Operates at 13.56 MHz on ISO/IEC 18000-3 air interface and at rates ranging from 106 Kbit/s to 424 Kbit/s • Requires low power • Compatible with contactless RFID technology
- 4. Communication Modes Device A Device B Description Active Active When a device sends, it generates an RF field. When waiting for data, a device doesn’t generate an RF field. Thus, the RF field is alternately generated by Device A and Device B. Active Passive The RF field is generated by Device A only. Passive Active The RF field is generated by Device B only.
- 5. Why NFC ?
- 9. The Solution
- 10. The Solution (Cont.) • Establishing a secure channel between two NFC devices is the best approach to protect against eavesdropping and any kind of data modification attack. • The NFC Specific Key Agreement
- 11. Future Prospects • Vehicle Ignition A NFC enabled vehicle can be unlocked and started just by tapping the user’s NFC device onto the vehicle removing the need of carrying a pair of keys. It can even be used to communicate between the device and the vehicle and monitor the vehicle’s health through some specific app • Unlock Door Smart keyless doors can be made by implementing NFC technology onto doors, where a single tap of the device onto the door would unlock it eradicating the pain of inserting the key and unlocking it.
- 12. Latest news about NFC • Google is working with Citigroup and MasterCard on NFC mobile payment solution • Airlines move closer to NFC tech for passengers- NFC allows a Smartphone to be used to "tap and check-in" or "tap and board" their flight • Nintendo's Wii successor, the Wii U, will come equipped with near-field communication (NFC) technology • Nokia went on record to say that all future Symbian devices will have built-in NFC support, a de-facto feature • Recently “Ra.One” became the first Indian movie to be marketed through NFC
- 13. Conclusion NFC has the potential to be a disruptive technology, changing the way that lives are lived, transforming everyday tasks, making things easier, more intuitive and more effective A significant advantage of this technique is the compatibility with existing RFID infrastructures. Additionally it would bring benefits to the setup of longer-range wireless techniques such as Bluetooth Though security concerns are present, they can be overcome through the use of various schemes such as setting up a secure channel, combined with which NFC can provide confidentiality, integrity and authenticity
