Apart from inventory control, RFID can be used to prevent international crime (AIM, 2006). In 2004, there were more than 20 million freight containers circulating throughout the world. Countries such as the United States received 7 million containers per year but only about 5 percent of them were physically inspected (Flynn, 2006). While commercial ﬁrms are often concerned with missing items in the containers when their customers open them, national security is more concerned about having unwanted items in the containers. Unchecked containers could harbor illegal immigrants or even terrorists (Sopensky, 2005).
The spacious container may also contain hazardous materials or weapons of mass destruction that may pose a threat to the stability of a nation. RFID tagging allows tracking of container movement prior to arrival. Security officials may use this information to apply appropriate security measures to individual containers upon arrival at the port. RFID technology can also register unscheduled opening and resealing of containers. Thus, if a container stopped at various ports prior to arrival and was opened and resealed in one or more of those ports, security officials may be alerted to this non-normal travel history and inspect the container.
