Abstract: Method, container corner lock and system for fastening a first container corner casting of a first container and a corresponding second container corner casting of a second container. The first container is stacked on the second container. The container corner lock includes: a first protruding part; including a first locking for fixing the first protruding part into the first recess; a second protruding part, including a second locking for fixing the second protruding part into the second recess; an electric motor configured to block or unblock the movement of at least one of the locking means; a first wireless transceiver; a processing circuit configured to receive the signal from the wireless transceiver and generate a command for operating the electric motor and a second wireless transceiver or transponder with a shorter range than said first wireless transceiver.
