    • Identification tags (22) are secured to objects (20) moving upon a transport band (16). The identification tags (22) each contain a transponder circuit (32) in electrical communication with transponder antennae (30, 31). The transponder circuit (32) contains a unique digital code containing data relating to the object (20). When the identification tag (22) is located beneath the object (20), at least one reader antenna (25) is positioned beneath the transport band (16) and in alignment with a selected aperture (34) extending through a support plate (12). One or more apertures (34) in alignment with the reader antenna (25) provide capacitive coupling between the transponder antennae (30, 31) and the reader antenna (25). The reader circuit (28) generates a signal in the presence of an identification tag (22), which is transmitted to the transponder antenna (30) located on the identification tag (22). The signal energizes the transponder circuit (32), which sends a transponder signal via the transponder antenna (30) back to the reader antenna (25). The reader circuit (28) demodulates the transponder signal to identify the data.

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

    • A hand-held dual reading head including a hand-held housing having a light transmissive window at one end thereof; and containing an actuatable bar-code reader, which produces a light beam which exits the housing via the window and detects light from the beam reflected from a bar code tag to generate a first electrical signal corresponding to bar code data read from the tag. The housing also contains an actuatable radio frequency tag reader which includes a transmit/receive coil mounted adjacent the one end of the housing containing the window, for producing a radio frequency signal of a first frequency to energize a radio frequency transponder-type identification tag and for receiving an identifying signal of a second frequency transmitted by an energized radio frequency identification tag to provide a second electrical output signal corresponding to the tag identifying signal, preferably in the same signal format as the bar-code data. The reading head has a common signal output connected to receive the first and second electrical signals, and a manually actuatable switch arrangement mounted on the housing for selectively actuating one of the bar-code tag reader and the radio frequency tag reader depending on the type tag to be read. Preferably, the housing is gun-shaped and the switch arrangement is a trigger-like normally OFF switch with two ON positions, one for each of the readers.
