Losing items has been a threat to each of us over the years. Apple’s 2021 introduction of AirTags has been a very successful device. But how does this small Bluetooth tracker exactly do? How does it achieve all of this?

An AirTag

This tiny little tracker uses Bluetooth technology and contains speakers and Apple’s U1 chip to locate lost items. They use a network of Apple devices to function. These AirTags can be connected to iPhone 6s or later and can be named to keep track of the ones connected to different objects. Lost items may be found using the Find My app under the Items tab.

If an object is nearby, you can ping its AirTag, which will play a sound you can follow.

On higher versions of iPhones, iPhones 11 and 12, an excellent feature named Precision Finding can be used. As its name suggests, it locates you at the exact point where the item is by giving you both the distance from the iPhone to the object and the precise direction to follow. This feature works by searching for a signal of an AirTag. Within 30–40 feet of the AirTag, it will be able to pinpoint you to the exact direction and give the precise distance. It also uses color coding to show if you’re moving in the right direction, with green meaning you’re moving right and black meaning you’re on the wrong path. If the item is on a different floor, you are notified about that too.

Precision Finding

However, if the item isn’t nearby and you left it somewhere, the AirTag can post its location to notify you about the place. The location is updated by sending a Bluetooth signal to an IOS device nearby. The process is entirely safe, secure, anonymous, and encrypted.

If you are still unable to find your item, you can put it into lost mode, which will notify you whenever it’s located.

Additionally, it uses NFC technology in case of lost objects. Anyone can scan the AirTag to access the owners’ contact details to ensure the item sees its way back to the owner.

Brilliantly, AirTags also prevent malicious use by dropping them into someone else’s belongings to track their location. This is done by noticing how long an AirTag is away from its owner and close to another person. Accordingly, the person being tracked will get a notification that an AirTag is nearby, and if required, it may start ringing to help the person to find it.

To sum up, this quarter-sized tracking device, filled with loads of features and technology, will help you find lost items and sort out the issue of missing things.

AirTags are water-resistant for up to 1 meter for 30 minutes, so it’s all right if they are rained on, or there is an accidental spillage. AirTags can also be customized by adding alphabets (to engrave your name or initials) or adding emojis instead of Apple’s icon. They work with batteries, so charging is not required. The 3V coin battery needs to be replaced only once a year. Up to 16 AirTags can be registered under one Apple ID so that you can keep track of 16 items simultaneously. External accessories can also be bought to make it easier to attach AirTags to items.

AirTags can be customized with your own text or emojis

However, AirTags only work with iPhones (or iPads) and cannot be used by Android users. Android users can still help Apple users find lost items by getting contact information by scanning the AirTag through their NFC-enabled devices.

This smart item tracker will ensure you keep all your items intact and lose the ability to lose things.
