Abstract
Systems for switchable RFID tags responsive to an environmental sensor are provided. In one embodiment, a system includes a RFID tag having an antenna and an integrated circuit electrically coupled to the antenna, a plurality of sensor devices electrically coupled to the integrated circuit, and an electrical connection between the integrated circuit and the plurality of sensor devices. The integrated circuit is configured to sense whether each of the plurality of sensor device is in a conductive state or in a non-conductive state, and produce a different output based on the state of the each of the plurality of sensor devices. The output is adapted to be transmitted through the antenna to a reader.
