i think maybe the gatekeeper term amex uses is more specifc to the Porter example with containers.

from Oct 29 2007 ann.

"The TZ Group will design and integrate Intevia technology into a CSD product, named “GateKeeper” that will provide a high security seal with authorized electronic access for the intermodal freight transport market.
The GateKeeper enabled with Intevia®technology will provide a new level of physical security. The device is keyless and easily attaches to the lock bars of any ISO container. Secure authorized access is achieved with TZ proprietary software downloaded to a (COTS) commercial off the shelf cell phone and a secure access code".

whereas the Intevia Enterprise entails a greater range and capacity of uses with internet connections etc.

exciting times move nearer.
