Abstract
A method and apparatus to ennumerate an aggregate of a stored product. An RFID tag attached to a product is interrogated to determine the product'"'"'s identity which implies the product'"'"'s unit weight. A gross weight of the stored product is determined by load sensors associated with the platform or container holding the product to be enumerated. A unit quanity of the stored product is determined from the product'"'"'s unit weight and the gross weight of the stored product.
