G06K19/0675 - CPC Classification

Classification description:

Record carriers for use with machines and with at least a part designed to carry digital markings characterised by the kind of the digital marking, e.g. shape, nature, code; Record carriers with conductive marks, printed circuits or semiconductor circuit elements, e.g. credit or identity cards also with resonating or responding marks without active components with resonating marks the resonating marks being of the surface acoustic wave [SAW] kind
