"NFC" stands for Near Field Communication, a technology that enables short-range communication between compatible devices. It allows for seamless data transfer by simply bringing two devices close together, usually within a few centimeters. NFC is commonly used in various applications, such as **contactless payments**, where users can tap their smartphones on terminals to complete transactions, and in settings like **public transportation** where NFC cards can be scanned for fare payment. Its convenience and speed make it a popular choice in modern mobile technology.
