RFID + GPS = WOW

It's possible I'm in the weeds about some of this stuff, but this sounds great. It's an implementation (done for a major bank that won't be named) that uses a combination of RFID tags on materials carried by trucks and GPS. As I understand it, there's a satellite module in the truck that sends up the local sensor data from the truck itself and the stuff on board.

The technology allows Eagle Global Logistics to securely transport everything from one tape backup of sensitive customer credit card data or two pallets of mortgage records.
The ARGO Tracker application uses a module in the truck that provides satellite communication, sending alerts to the call center when pre-determined thresholds are crossed. Attached to the module are sensors that monitor the truck's speed and location.
The tracking device also "acts as a hub or an edge router to collect other data and send it back to the data center," said Mike Hammons, chief executive officer at ARGO Tracker. "The module talks to all the tags and sends the information back over an encrypted connection."
Radio frequency identification (RFID) tags on the cargo doors, when opened, trigger a text message. "Any time the truck's speed is reduced to less than 10 miles per hour for less than a minute it sends an alarm to the dispatch center," Hindes said. "Our response time to any incident is less than 90 seconds."
