 These little trackers, I think they call them AirTags, made by Apple. And you can put them in your wallet or, you know, in your briefcase or your purse or wherever, and if you lose it, you can find it. So I misplaced my wallet. So I pull out that Find My Wallet, you know, and I'm looking, and finally I realize it's like one foot from me, because it was under my backpack, I think, which is kind of embarrassing, but it worked.
