The acronym "NFC" stands for Near Field Communication. This technology allows devices to communicate wirelessly over short distances, typically within a range of about 4 inches (10 cm). Commonly used in mobile payment systems and contactless cards, NFC enables quick and secure transactions without the need for physical contact. Its applications extend beyond payments to include data exchange and device pairing, making it convenient for users. As a result, NFC technology is becoming increasingly popular in various sectors, from retail to transportation, enhancing user experiences with seamless interactions.
