While the majority of smart luggage is still on the horizon, you can buy a LugLoc today for $70. Using a combination of GSM cellular network connectivity and Bluetooth LE, as well as a mobile app for Android and iOS, LugLoc slips into your bag and promises to help track your luggage. The first 15 days, or "traces," are free; after that, it's pay per use, with no subscription required. LugLoc has its skeptics, however. From a TripAdvisor user: "As we all know, it's very hard to get a good signal on either GPS or mobile/cellphone type devices when they are underground or surrounded by lots of concrete and steel. Oh, wait, I've just described the baggage sorting area of an airport terminal."
That's just one review, but the writer has a point. However, LugLoc says its product does not require GPS, only a GSM network connection, which "exists on every underground tunnel from every airport around the world, since that system is used by airlines to communicate with their personnel," according to the company.
