Apple AirTag

Apple AirTag is a small, coin-shaped device that can be attached to personal items like keys or wallets, allowing them to be located using the "Find My" app on an iPhone, iPad, or Mac. AirTag uses Bluetooth technology to communicate with nearby Apple devices, which then relay the item's location to the user. AirTag also includes a built-in speaker that can play a sound to help locate the item, as well as a removable battery that can last for up to a year.
