      Near Field Communication Technology<\/h5>\n\n\n\n
        \n
      • NFC is a short-range wireless connectivity technology that allows NFC-enabled devices to communicate with each other<\/strong> and transfer information quickly and easily with a single touch \u2013 whether to pay bills, exchange business cards, download coupons, or share a document.<\/li>\n\n\n\n
      • NFC transmits data through electromagnetic radio fields<\/strong>, to enable communication between two devices. Both devices must contain NFC chips<\/strong>, as transactions take place within a very short distance.<\/strong>\n
          \n
        • NFC-enabled devices must be either physically touching or within a few centimetres from each other for data transfer to occur.<\/strong><\/li>\n<\/ul>\n<\/li>\n\n\n\n
        • In 2004, consumer electronics companies, Nokia, Philips and Sony together formed the NFC Forum, which outlined the architecture for NFC technology to create powerful new consumer-driven products.<\/li>\n\n\n\n
        • Nokia released the first NFC-enabled phone in 2007.<\/li>\n\n\n\n
        • Other Applications:<\/strong>\n
            \n
          • It is used in contactless banking cards to perform money transactions<\/strong> or to generate contact-less tickets for public transport.\n
              \n
            • Contactless cards and readers use NFC in several applications from securing networks and buildings to monitoring inventory and sales, preventing auto theft, and running unmanned toll booths.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
            • It is present in speakers, household appliances, and other electronic devices<\/strong> that are controlled through smartphones.<\/li>\n\n\n\n
            • It also has an application in healthcare,<\/strong> to monitor patient stats through NFC-enabled wristbands. NFC is used in wireless charging<\/strong> too.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n
