Luggage

Lost your luggage? No problem. The TrakDot is a 3-inch tracker you place in your bag. At takeoff, the TrakDot senses the plane's acceleration and goes into auto standby. Then, when you land, it senses the braking, connects to a cell network, and sends you a text. You'll learn the exact airport location. It runs on two AA batteries and works with any carrier.
