What is NFC?
NFC, or Near Field Communication, is a short-range wireless communication technology that allows two devices to exchange small amounts of data when brought within a few centimeters of each other. It operates at 13.56 MHz and is most commonly used for contactless payments, access control cards, and quick device pairing. Unlike Wi-Fi or Bluetooth, NFC requires no manual pairing or configuration (proximity alone initiates the connection) making it ideal for fast, simple interactions where security through physical closeness is sufficient.
