The Problem

A strong locking bar or other form of barrier device can make overt break-ins to cargo containers difficult. But all conventional seals on the market are absolutely ineffective against covert break-ins – break-ins secretively perpetrated by people entrusted with the care and transportation of the container.

Whether the seal is made of the hardest steel or possesses the most sophisticated electronics, they are equally ineffective against covert break-ins for one simple reason: Conventional seals do not seal the container; they seal the container's handle to its door. As a result, when someone skilled in the technique of seal circumvention completes their break-in and cover-up, the seal can appear intact and unmolested even after a door has been opened and closed again.
