2. Introduction NFC word stands for Near Field Communication 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 NFC enabled electronic devices. Enables the exchange of data between devices over a distance of up to 20 centimeters. 3. NFC-enabled devices can simply point or touch their making application and data usage easy and convenient. 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. 4. Whats the use? Sharing Data, photos, web linksPairing Making a connection between equipment no need for passwords.Transaction Pay for anything 5. nfc tag simple electronic devices contain an antenna and a small amount of memory Passive and powered by a magnetic field 6. Works How NFC operates in two modes Active Mode: In this mode, both devices are generating their own RF fields. This would be in the case that two mobile devices are being used to exchange data. Passive Mode: In this mode, one of the devices generates the RF field and the other device uses the field to power itself and communicate. The active device is usually the reader and the passive device is the tag. 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. 7. Uses nfc Access Control: Replacing traditional keys for either physical access (hotel room) or control (starting a car)Ticketing: Replacing paper tickets for social events and public transportationContactless Payments: Mobile payments debited from financial or MNO linked accountsInteractive World: Marketing and exchange of information such as schedules, maps, business card and coupon delivery using NFC Marketing tagsMedia Sharing: Transfer images, videos, music between mobile phonesSocial media e.g. "Like" on Facebook, "Follow" on Twitter via NFC smart stickers in retail stores 8. Benefits Intuitive NFC interactions require no more than a simple touch Versatile NFC is ideally suited to the broadest range of industries, environments, and uses Open and standards-based - The underlying layers of NFC technology follow universally implemented standards Technology-enabling - NFC facilitates fast and simple setup of wireless technologies, such as Bluetooth, Wi-Fi, etc. Inherently secure - NFC transmissions are short range (from a touch to a few centimetres) Interoperable NFC works with existing contactless card technologies Security-ready - NFC has built-in capabilities to support secure applications
