It’s a disc-shaped tracking gadget that can be attached to items like house keys to help you find them. But inside, the story gets far more interesting. The AirTag, which Apple introduced last week, is one of the first consumer electronics to support a new wireless technology, ultrawideband, which lets you detect precise proximity between objects. Using ultrawideband, your iPhone can sense whether an AirTag is an inch or dozens of feet away from it. It’s so accurate that its app will even show an arrow pointing you in the direction of the AirTag.
