Going home during the Chinese New Year, in addition to the cumbersome purchase of tickets, the tiredness of the journey, what are you most worried about? For many students who want to travel long distances, I am afraid there is nothing more worrying about the safety of checked baggage. Today's violent transport companies are endless. If you can't carry them with you, how can you ensure the safety of your luggage?

The British company Cambridge Consultants thought of a good way to label the luggage with an electronic tag and let it record its own "journey" and report the owner at any time in case of danger. The name of this electronic tag is called DropTag.

DropTag is actually a collection of simple, low-cost sensors and Bluetooth communication units. Data collected by sensors such as gyroscopes, temperature, acceleration, humidity, etc., DropTag can record what happened to your package during transportation. If your baggage is abused by the shipping company, it will immediately connect to your phone via Bluetooth. Alert the owner.

Cambridge Consultants has developed a mobile app to manage this data and provide a valuable reference report after the shipment. DropTag's maximum communication distance is 50 meters, which is a conservative number for Bluetooth 4.0 with a theoretical transmission distance of more than 100 meters.

There is no more details on the DropTag e-label. Cambridge Consultants will show it at the Hannover Messe in Germany on April 8th, and we will analyze it for you.
