摘要: Identification tags are secured to parcels moving upon a conveyor belt. The identification each contain transponder circuit in electrical communication with antenna. contains unique digital code containing data relating the parcel. When tag is located beneath parcel, at least one reader positioned belt alignment selected aperture extending through the. One or more apertures antenna provide generates signal presence of an tag, which transmitted on tag. energizes sends via back from circuit, where analyzed identify contents
