Patent number: 9483748Abstract: Electronic Product Codes (EPCs) can be read from RFID labels and tags to verify shipments. The EPCs are decoded to Global Trade Item Numbers (GTINs), which are then matched to GTINs of products on a shipping list. If all of the decoded GTINs match and there are no GTINs in the shipment list that are left unmatched, then shipment verification is successful. If some of the decoded GTINs fail to match, the verification process fails with extra, unexpected products. If some of the GTINs in the shipping list are left unmatched, the verification process fails with the missing products.Type: GrantFiled: October 8, 2008Date of Patent: November 1, 2016Inventors: Qiming Huang, Christopher Rusnak
