Near-Field Communication (NFC) is a short-range wireless communication technology that enables devices to exchange data when they are in close proximity, typically within a few centimeters. Operating through magnetic field induction, NFC has become an integral part of modern digital interactions, offering a seamless and efficient way to connect devices and transfer information.<\/p>\n\n\n\n

How NFC Works<\/strong><\/p>\n\n\n\n

NFC operates on the principle of electromagnetic induction between two loop antennas when they are brought close together. This proximity allows for the transfer of data without the need for physical connectors or complex setup procedures. NFC devices can function in three modes:<\/p>\n\n\n\n

    \n
  1. Reader\/Writer Mode<\/strong>: One device reads or writes data to an NFC tag, which is a passive storage medium.<\/li>\n\n\n\n
  2. Peer-to-Peer Mode<\/strong>: Two NFC-enabled devices communicate directly to exchange information.<\/li>\n\n\n\n
  3. Card Emulation Mode<\/strong>: An NFC device emulates a contactless card, enabling transactions like mobile payments.<\/li>\n<\/ol>\n\n\n\n

    Applications of NFC<\/strong><\/p>\n\n\n\n

    NFC technology has a wide range of applications that enhance convenience and efficiency in daily life:<\/p>\n\n\n\n
