Near field communication (NFC) is a short-range wireless technology primarily for mobile devices, enabling communication through proximity. Developed by the NFC Forum and first implemented in devices like the Nokia 6131, NFC operates through inductive coupling, allowing various applications such as mobile payments and data transfer. The future of NFC includes potential developments in keyless entry systems, healthcare applications, and greater integration into smartphones for enhanced convenience.

- 2. WHAT IS NFC??? • NFC or Near Field Communication is a short range high frequency wireless communication technology. • A radio communication is established by touching the two phones or keeping them in a proximity of a few centimeters. • NFC is mainly aimed for mobile or handheld devices. • NFC is an extension of Radio frequency identification or RFID technology. • RFID is mainly used for tracking and identification by sending radio waves.
- 3. EVOLUTION OF NFC TECHNOLOGY • In 2004, NFC Forum was formed by Nokia, Philips, Sony,to set standards for NFC . Every NFC enabled device will have “N- Mark” trademark ,developed by NFC Forum. N MARK TRADEMARK
- 4. EVOLUTION OF NFC TECHNOLOGY • In 2006 First mobile phone( nokia 6131) with NFC released by NOKIA.
- 5. EVOLUTION OF NFC TECHNOLOGY • In 2010 First android phone SAMSUNG NEXUS S with NFC support released.
- 6. OPERATION OF NFC • Near field communication is based on inductive-coupling. • NFC works using magnetic induction between two loop antennas located within each other's 'near field’.
- 7. OPERATION OF NFC • operating frequency 13.56 MHz.data rate 106 kbit/s to 424 kbit/s. • NFC use an initiator and a target; the initiator actively generates an RF field that can power a passive target. Target
- 8. MODES OF OPERTAION MODES OF OPERATION ACTIVE MODE PASSIVE MODE
- 9. MODES OF OPERATION • In Active mode, both devices with NFC chip generates an electromagnetic field and exchange data. Two NFC enabled devices transfer -ring data in active mode
- 10. MODES OF OPERATION • In Passive mode, there is only one active device and the other uses that field to exchange information. A NFC- enabled mobile phone is paired with a RFID-tagged "smart poster"
- 11. APPLICATION OF NFC • NFC applications can be split into the following three basic categories: Touch and Go Touch and Confirm Touch and Connect
- 12. APPLICATION OF NFC • Touch and Go Applications such as access control or transport/event ticketing, where the user needs only to bring the device storing the ticket or access code close to the reader. Example for picking up an Internet URL from a smart label on a poster. Touch and go Mode of application
- 13. APPLICATION OF NFC • Touch and Confirm Applications such as mobile payment where the user has to confirm the interaction by entering a password or just accepting the transaction.
- 14. APPLICATION OF NFC • Touch and Connect Linking two NFC-enabled devices to enable peer to peer transfer of data such as downloading music, exchanging images or synchronizing address books. Data transfer via NFC
- 15. COMPARISON WITH EXISTING TECHNOLOGY
- 16. SOME DEVICES USING NFC TECHNOLOGY • Nexus S • Google Nexus S 4G • Samsung Galaxy S 7 • Apple iPhone 6s • Xiaomi Mi 5 • Nokia 6212 Classic • Nokia 6131 NFC
- 17. DEVICES WITH NFC TECHNOLOGY
- 18. ADVANTAGES OF NFC • High convenience to the user, because the data exchange is done by bringing two mobiles together. • Reduces cost of electronic issuance . • Secure communication. • No special software. • No manual configuration and settings. • No search and pair procedure.
- 19. DISADVANTAGES OF NFC • The system has the limitation that it can be operated only with devices under a short range i.e around 10 cm. • The data transfer rate is very less at about 106kbps to 424kbps.
- 20. FUTURE OF NFC • New generations of iPhone, iPod and iPad products would reportedly be equipped with NFC capability which would enable small-scale monetary transactions. • Recently, Microsoft announced that all Windows Phone 10 devices will make use of the NFC technology.
- 21. FUTURE OF NFC • Throw your wallet in the bin and chop up all your credit cards, because with NFC your smartphone becomes an all in one payment device. Instead of fumbling around with cash or watching how much you spend on your credit card, you simply wave your phone at an NFC enabled kiosk to pay for your items. • NFC technology is already being used by some companies for small payments. A cashless society
- 22. FUTURE OF NFC • Keys can be frustrating sometimes, you misplace them, loose them, they’re fiddly to use and they stick you in the leg when they’re in your pocket; but what if there was another way. NFC technology is already being used to open doors at hotels and at some businesses. In the next few years it may be able to open up a lot more. • NFC will soon be capable of replacing all of your keys and ID badges using only your phone. Open and start your car with the wave of a phone, open doors at you workplace and even your home safely and securely. • So, as more and more smartphones start to feature NFC and more and more developers create innovative ways to use it, we’ll get the full benefits of this technology. The possibilities are truly endless! Keyless entry for everything
- 23. FUTURE OF NFC • NFC has implications for the healthcare sector too. It could make it easier for patients to check in for examinations, renew prescriptions and pay for services and products, all through their phones. • NFC tags could also be embedded into patients’ charts meaning that doctors and nurses could quickly see what procedures are due and what has been completed, along with a patient’s prescriptions and medical history to help them administer the appropriate medicine and care. • There are currently trials taking place where diagnostic tags are affixed directly to the patient’s skin and monitor a range of things including temperature, glucose levels and other health information, all of which can be accessed by a doctor so that they can make a quicker diagnosis and administer more effective medications. More effective healthcare
- 24. CONCLUSION • Mobile handsets are the primary target for NFC and soon NFC will be implemented in most handheld devices. Even though NFC have the shortest range among radio frequency technologies, combining them with existing technologies like Bluetooth or Infrared can increase its range of applications.
