What does NFC stand for in wireless communications?

NFC stands for Near Field Communications, which is a set of communication protocols that allow two electronic devices to establish communication by bringing them within a few centimeters of each other. This technology is widely used for contactless payment systems, data exchange between devices, and electronic ticketing.

NFC operates at a frequency of 13.56 MHz and enables quick and secure transactions without the need for physical contact or complex setup processes. Its short-range capability adds a layer of security, making it suitable for applications where sensitive data transfer is involved. Understanding NFC is important in the context of mobile technology and everyday applications like mobile wallets, where quick and convenient transactions are key.
