What technology does Near Field Communication (NFC) use?

• A. Long-range radio waves
• B. Short-range communication between compatible devices
• C. Infrared signals
• D. Cable connections

Answer: (B)

Near Field Communication (NFC) technology operates through short-range communication between compatible devices. This capability allows two devices, such as smartphones or contactless payment systems, to exchange data when they are placed within a few centimeters of each other. The design of NFC enables secure connections suitable for transactions and information sharing by maintaining a very limited communication range. This makes it ideal for applications like mobile payments, ticketing, and pairing devices effortlessly, as the close proximity reduces the risk of interception by outside parties. The emphasis on short-range ensures convenience without sacrificing security, as it limits the scope of potential vulnerabilities associated with longer-range communication technologies. Thus, the ability to connect and communicate within such a short distance is a fundamental characteristic of NFC technology.
