Method for establishing a risk profile using RFID tags
First Claim
1. A system for a monitoring cargo container which is capable of transport by a vehicle and which is available to be weighed via a scale, the system comprising:
- a RFID reader that scans contents of the cargo container for RFID data regarding RFID tagged items in the cargo container;
a processor that is configured to estimate a payload weight of the cargo container according to the RFID data, wherein the processor is further configured to compare the payload weight measured by the scale with the payload weight determined from the RFID data, and for determining a risk factor according to a comparison of the two weights; and
a communication device, wherein the communication device signals an alert when the risk factor is high.

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.
