NFC: or Near Field Communication, is a wireless technology that allows devices to exchange information over short distances, typically within a few centimeters. It operates based on radio frequency identification (RFID), enabling secure and fast communication between compatible devices. NFC is commonly used in everyday applications like contactless payments (e.g., Apple Pay or Google Pay), sharing files, pairing devices, or even accessing information via NFC-enabled tags. It works by bringing two NFC-enabled devices or an NFC device and a tag close together, creating a low-power connection to transmit data. Since the range is so short, NFC is inherently secure, making it ideal for sensitive operations like payments. With its convenience and efficiency, NFC continues to simplify how we interact with technology in our daily lives.
