ABSTRACT:
An RFID weight-based security method with container compensation which compares total weights. The security method includes receiving item identification information from RFID labels affixed to items in a container, obtaining a reference container weight, obtaining reference item weights using the item identification information, obtaining a combined weight of the items and the container from a scale, comparing the combined weight with the sum of the reference container weight and the reference item weights, and processing payment for the items if the combined weight is within a predetermined threshold of the sum of the reference container weight and the reference item weights.
