I see a market for a purely "local" version of AirTag, consisting of the Bluetooth component only, for locating objects inside the home or office. Could such a stripped-down version be implementable as a stick-on device small enough to be attached to the eyeglasses, remotes, Apple Pencils, and other small objects that are always getting lost indoors? Could the battery be built-in and rechargeable with a MagSafe?
