This International Standard specifies methodologies to be used for the conformance of rewritable hybrid media data carriers, which combine RFID tag technology with linear and/or two-dimensional bar code symbologies that are written to an erasable substrate. Three main product configuration types are addressed within this International Standard:. Rewritable Media, which supports the rewriting of linear or two-dimensional symbols;. Rewritable Hybrid Media, which integrates the Rewritable Media with an RFID tag;. Rewritable Media combined with RFID technology that are physically separate data carriers but stillrequire their data encoding processes to be integr
