Abstract: The objective of the present invention is to provide a device for electronically sealing a container using proximity wireless communication for controlling the sealing of a container door from a remote distance by applying a proximity wireless communication technique to the device for electronically sealing a container, so that unlocking a container becomes more convenient, rapid, and safer, and to provide a system and a method for operating the device for electronically sealing a container.

Abstract: A device for sealing a container door are configured for the sake of a container security in such a way that the device for sealing a container door is installed at a locking device of a container door so as to detect if the container door is forcibly opened or closed by an unauthorized person during a container transportation from a freight-loaded place to a freight-unloaded place, and a result of such a detection is wirelessly transmitted to a container security system. The device for sealing a container door includes a main body, a locking member, a fixing unit, a stopper unit, a seal-release authentication unit, a holding unit, a seal-sensing unit, a LED state display unit, a battery, and a control board.
