There have been more than a few efforts at smart luggage, but this is one you're likely going to notice. Samsung and Samsonite (appropriately enough) are teaming up to develop smart bags that will likely be easier to buy and more accessible. They should include include loads of location and mobile notification features, such as GPS tracking, anti-tampering alerts and warnings when you wander away. However, that's just the start. Samsonite is working with airlines on baggage that checks itself in -- drop them off and they'd tell the airport about your airline, the weight and your destination. Also, Samsung is experimenting with self-propelled luggage that follows you around the airport. That last technology is still too cumbersome to be practical (the engine takes up a third of the size), but the days of having to lug (and worry about) your belongings across the airport may soon be over.
