DEVICE FOR ELECTRONICALLY SEALING CONTAINER USING PROXIMITY WIRELESS COMMUNICATION, AND SYSTEM AND METHOD FOR OPERATING SAME

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. The device for electronically sealing a container is coupled to a keychain outside of the container, so that whether the container door is open or closed can be checked in real time, and various types of information related to the container can be relayed, in real time, to a shipper or persons associated with tracking the container, thereby fundamentally eliminating the possibility of illegal opening and closing of container doors associated with existing container-locking devices, and also allowing convenient, rapid, and safe unlocking of container doors.
