AirTags, Apple Inc's (NASDAQ:AAPL) tiny Bluetooth companions, are not only useful, but they’re also affordable. At $29 per beacon, or $99 for four, it’s easy to buy them — and hard to lose them.
How AirTags Work: According to the website, the AirTag sends out a secure Bluetooth signal that can be detected by nearby devices in the Find My network. These devices send the location of the AirTag to iCloud and the user can then go to the Find My app and see it on a map.
