GE's security business (www.ge.com ) has completed the first commercial field test of the Tamper Evident Secure Container (TESC), a freight container developed jointly with the world's leading manufacturer of maritime shipping containers, China International Marine Containers Group Ltd. (CIMC).

The TESC, a standard container with an integrated CSD (iCSD) from GE, lets shippers add a unique, encrypted code after it is closed with a traditional bolt seal. As the container passes within range of the global wireless reader infrastructure, the iCSD tells logistics and customs officials where the container is located, when it arrived, and if unauthorized personnel opened it en route.

Container security expert Unisys tested the system under more than 15 different security breach attempts in China, Hong Kong, and the U.S. Unisys says embedding the container security device (CSD) within the container "enhances both the security and financial viability of this solution. We've tested many container security technologies and the CSD is the current gold standard." GE also offers CSDs that can be installed in less than a minute to retrofit existing containers.
