ABSTRACT:
A method and system is disclosed for enabling quantities of bulk-type products to be determined using RFID tags that can also be used to determine the existence of product or packaging containing RFID tags. Packaging and/or containers for the bulk products are configured so that the RFID tags contained thereon provide an indication of an approximate relative quantity of the bulk material. More specifically, the position and/or shielded or unshielded state of RFID tags are utilized to identify a quantity of the bulk-type material.
