Photos: At Accenture, RFID and sensors are on track

Not just a toy for children, these trains have RFID tags in each carriage that send signals to "reading points." A mesh network based on the ZigBee wireless specification handles communications between the wagons so that the cargo can be monitored. Sensors that monitor the status of the cargo can be embedded on the Zigbee board.

"If you are transporting sensitive materials, you can monitor the temperature," Hasson said. "Some plastics tend to fuse at a certain temperature and cannot be melted again. That can be catastrophic," he added.
