Abstract
There is disclosed method of shipment verification and/or tamper detection, wherein a purchaser generates an ordering document such as a purchase order RFID-encoded with data identifying items on the order. The supplier gathers the items into a package or packages for the shipment and RFID encodes the shipment with both data relating to the items ordered and to the shipping package weight. When the shipment arrives at the customer's location, the customer decodes the RFID package transponder and compares the items ordered with the items received and/or compares the decoded shipping package weight with the actual weight of the shipment and if there is an unallowable discrepancy in either or both, the customer is on notice that the shipment may be erroneous.
