NFC (Near Field Communication) is a wireless technology that allows devices to communicate and exchange data within a short range, typically a few centimeters. NFC is commonly used for tap to pay transactions, where a customer can use a contactless card or a smart device (such as a smartphone or a smartwatch) to make payments by tapping or hovering over a compatible terminal. NFC is different from other wireless technologies, such as Wi-Fi, IR (Infrared), and Bluetooth, because it does not require pairing, authentication, or network access to work. NFC is also faster, more secure, and more convenient than other payment methods, such as inserting or swiping a card.Reference:CompTIA IT Fundamentals (ITF+) Certification Guide, page 25;What is Tap to Pay and How Does It Work?
