"The Port of Duisburg (Duisport), the world’s largest inland port, located near the confluence of Germany’s Rhine and Ruhr rivers, has developed what it calls a Rivergate, through which the ID of each container being loaded on, or unloaded from, a vessel is digitally recorded and compared with the ship’s loading list within seconds. The system also records the condition of each container, including the integrity of the customs seal, as it is handled." See the original at Splash247.
