The AirTag is a small, circular tag that you can attach to your keys, bag, or any other item you want to keep track of. It uses Bluetooth technology to communicate with your iPhone, iPad, or iPod touch, and can help you locate a lost item by showing its location on a map in the Find My app. You can also set up notifications so that you’ll be alerted when an AirTag arrives at or leaves a location, such as your home or office. The AirTag is made by Apple and was introduced on April 20, 2021.
The AirTag uses Bluetooth technology to communicate with your iPhone, iPad, or iPod touch. It connects to these devices using Bluetooth Low Energy (BLE), which is a wireless networking protocol that is designed to be energy-efficient and allow devices to communicate with each other over short distances. The AirTag also uses other technologies, such as GPS and cellular data, to help determine its location and provide accurate location information to the Find My app. It’s worth noting that the AirTag does not have a built-in GPS receiver, so it relies on other devices to help determine its location.
