Methods and apparatuses for assembling and implementing optically machine readable radio frequency identification (RFID) tags are described. An RFID tag comprises a substrate, an electrical circuit mounted on the substrate, and an antenna that is configured to be machine readable. For example, the antenna may include a plurality of electrically conductive substantially rectangular bars formed on a first surface of the substrate. Bars of the plurality of electrically conductive substantially rectangular bars are positioned in parallel with each other and are configured to be an optically machine readable symbol. Bars of the plurality of electrically conductive substantially rectangular bars form at least one antenna. The electrical circuit is electrically coupled to the plurality of electrically conductive substantially rectangular bars. Alternatively, a plurality of patches are formed on the first surface of the substrate to form a two-dimensional optically machine readable symbol.
