A system verifying an item in a package comprises a package producer and a verifier. The package producer produces a package with a label, wherein the package includes an item each with one or more selected tag identifiers that are placed in a location on the item. The verifier verifies the item using 1) the one or more selected tag identifiers as detected using a spectral measurement or 2) a location or a shape of the one or more selected tag identifiers on the item, and 3) the label as read using a label reader.
