One year after the first rumors, AirTag is finally on the market. A new gadget from there Apple that it is already making waves, first of all for its utility as well as for its affordable price. I think it 's the cheapest device Apple, but also one that touches a key market and that will be difficult to copy. I will also explain why if another manufacturer launched something similar, it would not have the same success.

What is a Apple AirTag? 

A small round, coin-shaped device that attached to the keys or put in your wallet will can help locate accurately from iPhone, iPad, Mac or from the account iCloud, the object to which it was attached. A diameter of 31.9 millimeters, 8.0 mm thick and a weight of 11 grams, are made of AirTag a gadget easy to put in your wallet, in your bag, to attach to keys, as a child, cat or dog.

So you have to have at least an iPhone, and things you don't intend to miss, the location gadget AirTag it is definitely helpful. Especially since the price in stores is around 34 EUR, and the design is impeccable. Minimalist and premium, which can be completed with a keychain holder for a key or backpack.

Apple also launched a package of 4 AirTag for $ 99. The price in stores for the end customer is about 117 EUR, if you can't order it directly from Apple.com or buy it from one Apple Shop (shop Apple, not partners).
To order online on apple.com you also have the possibility to customize Airtag with emoji or your desired name. The engraving is free.

Let's see how it works AirTag and in which scenarios it is useful to us.

AirTag (tracker) - Operating mode

As I said above, you need to have an iPhone to pair with AirTag.

After "pair" / "Connect" you can give a name for AirTag. In case you will use more AirTag, it's good to know where it is.
Once connected, AirTag will be added to your list of devices in the application "Find My". From there you can locate it at any time, whether you run the application on your iPhone, iPad, or MacBook iMac.
iPhone too AirTag they still have a more special "chemistry". With the iPhone 11, Apple inserted the U1 chip. This chip present in iPhone 11, iPhone 12 si AirTag will also allow ultra-wideband (UWB) localization. Here I have to make a parenthesis in which I have to explain exactly what this U1 chip does.

U1 is a dedicated chip for precise location (Precision Finding), able to show you the distance and direction of the searched device, when you are in his proximity. An arrow will appear on the iPhone screen to point you in the right direction AirTag.

However, to enjoy "Precision Finding”You need to have a iPhone 11 or iPhone 12 (all models).

Besides the "map" on the screen, during user location detection will get haptic signals (sensitive, by vibration) and / or sound, depending on how close or far away it is from AirTag. "Fire, fire, fire, water, water, fire."

And yet, how it can be located AirTag if it reaches an area far from your iPhone. Well, a device with a U1 chip has the ability to connect to search network Apple (Find My network) through the iPhone devices that appear in his vicinity. The ultra-wideband connection will be totally encrypted, anonymous and "invisible". In this way AirTag can be located anywhere through the application Find My or online from the account iCloud.

Let's take the scenario in which a wallet is stolen in which you have a AirTag and the person who took it immediately goes to another city. Automatic AirTag has gone out of the "coverage area" of your iPhone, but it is enough that AirTag to pass a few meters from an iPhone device. At that moment, it will use the nearby device and send the location to the owner. Experiments have already been done in which it was shown that to be located, it is enough to be in the pocket of someone walking on the sidewalk, and for a car with an iPhone to pass on the street.
In conclusion, AirTag can be located almost anywhere. The number of iPhone owners is considerable, and this will certainly help in locating them AirTag.

After which Apple they withdrew the first model of Magic Mouse, I think AirTag it remained the only device in the ecosystem where the user can change the battery alone. AirTag works with a battery CR2032 which ensures an autonomy of up to 1 year in conditions of average use. That is, no more than 2-3 pings location per day.

If you are the owner of a AirTag you can share the experience with this device in the comments.

I am happy to share my experiences in the field of computers, mobile phones and operating systems, to develop web projects and to bring the most useful tutorials and advice. I like to "play" on the iPhone, MacBook Pro, iPad, AirPort Extreme and on operating systems macOS, iOS, Android and Windows.
