Mobile Devices

An IT specialist compares Bluetooth and NFC technologies for mobile device connectivity. Which of the following statements accurately describes a key difference between the two?

Explanation

NFC (Near Field Communication) operates within a very short range of approximately 10 centimeters, while Bluetooth can connect devices up to 32 feet (10 meters) or more depending on class and version.
