GAO Report Says Cargo Container Security Technology Still Work in Progress
- The Container Security Device (CSD), to detect the opening or removal of container doors. - The Marine Asset Tag Tracking System (MATTS), to track containers.
- The Advanced Container Security Device (ACSD), intended to detect intrusion on all six sides of a container.
- A lightweight container with a built-in sensor grid known as the Hybrid Composite Container. The latter two have yet to complete laboratory evaluations and aren't scheduled for completion until 2012 due to technological challenges, the report said.
