AbstractProvision is made for identifying tools used in an automated machine tool system. A module or transponder is mounted to the tool and interrogated by a transceiver which, in the preferred embodiments, has read/write capabilities. The transponder uses energy from the transmitted signal to power itself and send information stored in its memory back to the transceiver. In one embodiment, electromagnetic energy is transmitted from the transceiver to the transponder while the transponder to transceiver communication link is provided by way of capacitive coupling.
