Answer: (c) 1 and 3 only

Near Field Communication Technology
  • NFC is a short-range wireless connectivity technology that allows NFC-enabled devices to communicate with each other and transfer information quickly and easily with a single touch – whether to pay bills, exchange business cards, download coupons, or share a document.
  • NFC transmits data through electromagnetic radio fields, to enable communication between two devices. Both devices must contain NFC chips, as transactions take place within a very short distance.
    • NFC-enabled devices must be either physically touching or within a few centimetres from each other for data transfer to occur.
  • 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.
  • Nokia released the first NFC-enabled phone in 2007.
  • Other Applications:
    • It is used in contactless banking cards to perform money transactions or to generate contact-less tickets for public transport.
      • 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.
    • It is present in speakers, household appliances, and other electronic devices that are controlled through smartphones.
    • It also has an application in healthcare, to monitor patient stats through NFC-enabled wristbands. NFC is used in wireless charging too.
