Methods and systems for GPS-enabled baggage tags

An electronic baggage tag, the tag comprising:

• a microcontroller, a memory, a GPS module, a power source, a communications component, and a plurality of sensors, wherein at least one of the plurality of sensors is a vibration sensor;
• wherein the tag is configured to:
• receive an initial itinerary via the communications component while the tag is in a first mode, the initial itinerary stored in the memory;
• detect stimuli using the plurality of sensors;
• enter a second mode when a first type of sequence of stimuli is detected using the plurality of sensors, wherein the tag does not receive or transmit GPS data or communications while in the second mode except for receiving updated itinerary data;
• exit the second mode when a second type of sequence of stimuli is detected using the plurality of sensors;
• return to the first mode from the second mode when vibrations are detected that match a specific vibration profile;
• download a plurality of vibration profiles from a remote server;
• and
• store the plurality of vibration profiles in the memory.
