ZOCA Container Security BV has developed an innovative approach to preventing unauthorized opening of shipping containers, a serious problem in today’s shipping industry. The ZOCA approach taps Iridium satellite data links to control the containers’ locking devices remotely. The ZOCA system consists of a strong mechanical tamper-proof lock, which can only be operated with a ZOCA handheld mobile device. In order to lock or unlock the container, the handheld instrument must be plugged into a connection on the outside of the container. The control unit sends a security code for the lock to a central computer at ZOCA’s global processing center through Iridium’s constellation of 66 low-earth orbiting satellites. The central computer confirms the correct security code.
