NFC (Near Field Communication)

Near Field Communication (NFC) is a wireless technology that allows two devices to communicate instantly when they are very close—typically within a couple of centimeters. It's used for quick, secure data exchanges such as mobile payments, sharing contacts, or pairing devices like headphones. NFC works by using radio frequency signals to establish a small, encrypted connection, making transactions fast and secure without needing internet access. It's integrated into many smartphones, enabling convenient, contactless interactions with compatible devices and payment terminals.
