Near Field Communication is used primarily for which purpose?

• A. Wireless charging
• B. Near Field Communication (NFC)
• C. Bluetooth Low Energy
• D. High-security offline storage

Answer: (B)

Short-range, contactless communication is what NFC is built for. NFC enables devices to exchange data quickly and securely by being held very close together—typically a few centimeters apart. That makes it ideal for things like tapping a card to pay, exchanging a small amount of information between phones, or quickly pairing devices with a tap. The option that literally names the technology—NFC itself—best captures its primary use, because the technology is defined by enabling this near-field communication.

The other options describe things that aren’t the main function of NFC: wireless charging involves power transfer over inductive links rather than data exchange, Bluetooth Low Energy covers longer-range wireless communication for ongoing connections, and high-security offline storage is a separate capability not specific to NFC.
