I wonder what model they used. I don’t think I’ve seen one of those trackers that could be hidden in a postcard

If this thing is like an Apple AirTag or Milwaukee One-Key - there's another leak somewhere on that ship! Bluetooth isn't strong enough to reach anywhere from sea, and they don't have GPS or satellite communications built in. Which means they're allowing iPhones and/or Android devices that are doing the communications for the bluetooth dongle - and have access to GPS. Seems a much bigger issue than adding some additional mail sorting equipment.
