Devices and methods are provided for wireless communication with a target, such as an optical disc or an electronic device. The devices include an integrated processor and an antenna that are connected to the target, which enable a wireless communication with an associated reader or scanning system. The integrated circuit may be embedded in the target attached to the surface of the target, or in a label attached to the target. In a similar manner, the antenna may be embedded in the target, attached to the surface of the target, or in a label attached to the target. Interconnection lines may be used connect the integrated processor to the antenna, and may include a feedthrough arrangement for passing electrical signals between the surface and the interior of the target. A demodulator may also be positioned adjacent or on the antenna, allowing a long lead line to pass demodulated data to the integrated circuit. In one example, the antenna is positioned in or on a case that holds the target, with lead lines connecting the antenna to the target's integrated circuit. One, two, or three antennas may be used, with the multi-antenna arrangements preferably arranging the antennas orthogonally.
