"Trakdot™ Luggage is constantly monitoring the cellular network to determine it's city location. When you fly, Trakdot™ Luggage knows and goes to sleep. Upon arriving at your destination, Trakdot™ Luggage wakes up and reports it's new location. Depending on your preferences, a text-message or email is sent to you confirming that your luggage has arrived with you."
TrakDot comes out in March 2013 for $49.95 plus activation and service fees.
