The acronym "NFC" stands for Near Field Communication. It is a short-range wireless technology that enables devices, usually within a distance of about 4 centimeters, to communicate and exchange data. NFC is commonly utilized in mobile payments, allowing consumers to make transactions by simply tapping their mobile device against a payment terminal. It also plays a role in other applications, such as ticketing, smart posters, and connecting devices seamlessly. Its quick and easy operation makes it a popular choice for enhancing user convenience in various settings.
