Following their agreement late last year with Sweden-based All Set Marine Security, General Electric Infrastructure Security has now begun field-testing the CommerceGuard‘, a palm-sized wireless container security device (CSD). Consisting of the CSD, wireless readers, and the CommerceGuard Information Network, the equipment controls authorized access to containers and monitors for signs of intrusion. The CSD is armed with a unique identifier code using a handheld wireless device and in conjunction with fixed wireless readers at ports, one is able to indicate where and when a container has been opened since it was originally sealed. Customs officials are also able to arm and disarm the cargo for inspection using another handheld device. No tools special tools are needed as the CSD fastens easily to the door jamb inside any standard maritime container.
