Apple’s AirTag is an example of an IoT device that uses NFC. a. True 20. b. False
The correct answer and explanation is:
The correct answer is b. False.
Apple’s AirTag is an example of an Internet of Things (IoT) device, but it does not rely on Near Field Communication (NFC) as its primary technology. Instead, AirTag primarily uses Bluetooth Low Energy (BLE) to communicate with nearby Apple devices. When an AirTag is within range of a Bluetooth-enabled device, such as an iPhone, it can be detected and tracked using the “Find My” app.
NFC, on the other hand, is a short-range wireless technology commonly used for communication between devices that are in very close proximity, typically within a few centimeters. Although AirTag has an NFC chip built in, its primary function is not NFC-based. Instead, the NFC feature allows anyone who finds a lost AirTag to tap it with their smartphone (even if it’s not an Apple device) to quickly access contact information if the owner has provided it.
The use of Bluetooth enables AirTags to have a much larger range compared to NFC, as Bluetooth signals can cover distances of up to 100 meters, depending on environmental conditions. This makes it much more suitable for tracking objects over a wider area, which is one of the reasons AirTags are popular for locating lost personal items like keys, bags, or wallets.
In summary, while AirTags do feature NFC, their primary communication protocol is Bluetooth, which is better suited for the tracking capabilities the device offers. Therefore, it is inaccurate to describe AirTag as relying primarily on NFC.
