Drug traffickers hack shipping containers

I met some interesting guy when having a coffee outside, who showed me some stuff he develops at his company.. holy shit, it was unlike anything I had ever imagined that shipping container technology was close to.

He sold something like google-glass, connected to remotely controlled electronic lock-systems for shipping containers. Those also allowed to visually track where a container is and if the lock is open/closed etc. A guy could run around, check containers and unlock containers, all by done by looking through the glasses and talking through radio.
