Near Field Communication (NFC) is a technology that allows devices to communicate wirelessly when they are close to each other, typically within a few centimeters. It is commonly used in mobile payments, where smartphones can make transactions by simply tapping them against a payment terminal. NFC operates on a set of standards that enable secure data exchange between devices. NFC is also used for various applications, such as sharing files, connecting to Bluetooth devices, and accessing public transport systems. Many smartphones and smartwatches come equipped with NFC capabilities, making it a convenient option for users to interact with their surroundings effortlessly.
