Near field communication (nfc) technology

  1. 1. Near Field Communication (NFC) Technology
  2. 2. Introduction to NFC 2 • NFC is one of the latest wireless communication technologies. As a short-range wireless connectivity technology, NFC offers safe — yet simple and intuitive — communication between electronic devices. • Enables the exchange of data between devices over a distance of up to 20 centimeters (4 cm Practically). But with the software implementation techniques, you probably have to touch the devices. • NFC-enabled devices can simply point or touch, making application and data usage easy and convenient. • The design includes a near-field transmitter and receiver to send data from one device to another
  3. 3. 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 (initiator/target) 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 be read and written by the reader. • Maximum transfer bit rate of 800kbps. • No special software is required. 3
  4. 4. TYPES OF MODE Modes Passive Active Passive Mode Active Mode The initiator device provides a carrier fields and the target device answers by modulating the existing field. Both initiator and target device communicate by alternately generating their own fields. A device deactivates its RF field while it is waiting for data. In this mode, the target device may draw its operating power from the initiator- provided electromagnetic field. In this mode, both devices typically have power supplies.
  5. 5. HISTORY Year Event 1983 The first patent to be associated with the abbreviation RFID was granted to Charles Walton. 2004 Nokia, Philips and Sony established the Near Field Communication (NFC) Forum 2006 Initial specifications for NFC Tags 2006 Nokia 6131 was the first NFC phone 2009 In January, NFC Forum released Peer-to-Peer standards to transfer contact, URL, initiate Bluetooth, etc. 2010 Samsung Nexus S: First Android NFC phone shown 2011 Google I/O "How to NFC" demonstrates NFC to initiate a game and to share a contact, URL, app, video, etc. 2011 NFC support becomes part of the Symbian mobile operating system with the release of Symbian Anna version 2011 RIM is the first company for its devices is certified by MasterCard Worldwide, the functionality of PayPass 2014 Apple introduced Apple Pay for NFC-enabled mobile payment on iPhone 6, iPhone 6 Plus, and the Apple Watch when Apple releases it in early 2015.
  6. 6. COMPARISON WITH OTHER TECHNOLOGIES
  7. 7. USES • NFC devices can be used in contactless payment systems, similar to those currently used in credit cards and electronic ticket smartcards, and allow mobile payment to replace or supplement these systems. • For example, Google Wallet allows consumers to store credit card information in a virtual wallet and then use an NFC-enabled device at terminals that also accept MasterCard PayPass transactions. Germany, Austria and Latvia have trailed NFC ticketing systems for public transport. And China is using it all over the country in public bus transport. • NFC offers a low-speed connection with extremely simple setup, and could be used to bootstrap more capable wireless connections. It could, for example, replace the pairing step of establishing Bluetooth connections or the configuration of Wi- Fi networks. • NFC can be used in social networking situations, such as sharing contacts, photos, videos or files, and entering multiplayer mobile games. • The NFC Forum promotes the potential for NFC-enabled devices to act as electronic identity documents and keycards. As NFC has a short range and supports encryption, it may be more suitable than earlier, less private RFID systems. 7
  8. 8. EXAMPLES OF USING NFC ENABLED MOBILE PHONES • Download music or video from a smart poster. • Exchange business cards • Pay bus or train or air or taxi fare, etc. • Parking Tickets • Pay at Kiosks • Pay and purchase at Point of Sale Terminals (POST) • Access controls in office, hotels, airports, etc. • Print receipts to printer 8
  9. 9. NFC AND MOBILE PAYMENT 9
  10. 10. ADDING NFC TO TERMINALS ADDS VALUE TO MOBILE PAYMENTS 10
  11. 11. THE NFC ECOSYSTEM IS BROAD 11
  12. 12. WHAT IS THE FUTURE? • Nokia is active in the area of NFC since 2004 • Together with Philips and Sony, founded the NFC Forum. • Currently, global membership in the NFC Forum had exceeded 140 organizations. 12
