AirTag — is a small device from Apple designed to track objects using Bluetooth technology.
It is a compact tracker that can be attached to keys, wallet, bag and other items to easily locate them using the app. Find My on iPhone.
Let's take a closer look at how AirTag works, what technologies it uses, and what benefits it provides to users.
1. Device and connection
AirTag — This compact gadget measures 31.9 mm in diameter, 8 mm in thickness, and weighs approximately 11 grams. It is powered by a standard CR2032 battery, which lasts up to a year without replacement.
Pairing the tracker is very simple: simply hold it close to your iPhone, and the device will automatically recognize the AirTag, prompting you to add it to your network of devices through the Find My app. After that, the AirTag will be linked to your Apple ID account.
The key element of the technology is Bluetooth LE (Low Energy), which is used to connect AirTag to your iPhone and other Apple devices.

2. Search for lost things
AirTag uses ultra-wideband (UWB) technology, which significantly improves search accuracy. This is made possible by the U1 chip built into both the tracker and the iPhone (starting with the iPhone 11 models). When an AirTag is nearby, the Find My app not only pinpoints its location but also uses Precision Finding mode to guide the user to its precise location, indicating distance and direction.
When an AirTag-equipped item is lost outside Bluetooth range, the Find My Network feature kicks in. Apple devices around the world that are connected to this network can detect your AirTag's signal and anonymously share its location with you via the cloud. This allows you to locate an item even if it's far away. For example, if your AirTag-equipped wallet is left in a cafe, a passing person with an iPhone could unknowingly help you locate the tracker.
3. Privacy and Security
One of the AirTag's key features is its high level of data security. Apple uses encryption to ensure user privacy, ensuring that even a device that accidentally finds your tracker won't be able to obtain personal data about you or the tracker. The AirTag's location is accessible only to you, and the data is online. Find My are transmitted in encrypted form.
Apple has also implemented several security features to prevent tracking. If someone else's AirTag is nearby and follows you for an extended period, your iPhone will alert you. If you don't have an iPhone but an unknown AirTag is nearby, the device will emit a sound to notify you of its discovery.
4. Examples of use
- Keys: One of the most popular use cases is attaching the AirTag to a keychain. This allows you to quickly find lost keys, especially if they've been misplaced in a hard-to-reach place around the house.
- Bags and luggage: AirTag can be used to track your luggage at the airport. If your baggage is lost, you can see its location and receive a notification as soon as someone with an Apple device comes near your suitcase.
- Pets: Pet owners often attach AirTags to their pets' collars to quickly locate them if they escape. However, it's important to remember that this device isn't designed for real-time tracking over long distances, like GPS trackers.
5. Limitations and disadvantages
The AirTag is a powerful device, but it has its limitations. The main drawback is the lack of its own GPS module, which limits its operation to Apple device coverage. Although the Find My network covers millions of devices worldwide, finding the AirTag can be difficult in remote areas or places with low Apple device density.
It's also worth noting that in some cases, the AirTag's security system to prevent tracking may not work as expected. There have been instances where alerts about someone else's AirTag have not always been triggered in a timely manner, especially if the tracker is located on a crowded street or in a public place.
Conclusion
AirTag is an innovative device that makes it easier to find lost items and provides Apple users with a convenient solution for tracking their everyday items. The device is easy to use, secure, and integrates with other Apple devices. Despite some limitations, it offers unique features and reliable privacy protection, making it a popular choice among Apple users.
