Abstract
A system and method for establishing a weight related risk profile using RFID technology is provided. While the cargo container is in transit, a RFID reader inside a cargo container polls the contents of the container by reading RFID data from each RFID tagged item and calculate the payload weight. When the truck transporting the cargo container passes a weigh station, or a high-speed scale embedded in the road, a payload weight is measured by a scale. A risk factor is assessed by comparing the estimated weight by the RFID reader with the measured weight by the scale. According to one aspect of the invention, the RFID based polling system has the ability to map the weight and location for each tagged item and estimate a container weight distribution. The estimated weight distribution is compared with the weight distribution measured by the scale to determine potential anomalies.
