NFC

NFC, or Near Field Communication, is a wireless technology that allows two devices to communicate when they are very close, typically a few centimeters apart. It enables quick, secure data exchanges—such as sharing contact information, making payments, or pairing devices—without needing internet or Bluetooth pairing. Think of it as a digital handshake: simply bringing your phone close to another device initiates a transfer or connection. NFC is commonly used in contactless payment methods like Apple Pay or Google Pay, and in settings like access control or quick device pairing.
