A device for nullifying an exception RFID tag associated with a product or package includes a label with a replacement RFID tag configured thereon. The label is configured for placement on a package or product adjacent to the exception RFID tag. An electromagnetic shield is configured on the label and has a size and configuration so as to extend over the exception RFID tag when the label is placed adjacent thereto so as to disable subsequent reading of the exception RFID tag.
