Quizplus · Accepted Answer

Near field communication (NFC) technology is designed for short-range wireless connectivity, typically up to 4 inches. It is commonly used in contactless payment systems, in which an NFC-enabled device like a credit card or smartphone can communicate with a payment reader. It is also used in other consumer electronics like smartphones, tablets, and smartwatches for tasks like sharing files, connecting to Bluetooth devices, and making mobile payments. Microwave transmission and Wi-Fi are not typically used for short-range connectivity, while wireless mesh networks are designed for larger-scale wireless connectivity between devices over a larger area.
