"What can be done with high-value items is to place them within 100m of a station, and the reader can continue to ping [the tag] to verify that item's still at that location," McInerney said.
Another possibility being investigated is using RFID sensors to detect unauthorised breaches of ordinance containers.
Sensors could monitor a number of details such as the temperature or light levels inside the container. A significant change of either measure would raise an alarm.
By 2010, Gartner forecasts worldwide RFID spending to surpass $US3 billion.
Gartner analyst, Jeff Woods, said organizations should not think of RFID tags as simply a replacement for bar codes as the technology is proving it isn't just for the supply chain anymore.
According to ABI Research undertaken in June this year, the technology is also being applied to asset management, security access control and specialized inventory management.
