Abstract
Systems for switchable RFID tags responsive to an environmental sensor are provided. In one embodiment, the system includes a primary RFID tag and a secondary RFID tag, and a switch being associated with the primary RFID tag and the secondary RFID tag in a manner that the primary RFID tag and the secondary RFID tag are not activated at the same time. Each RFID tag may include an integrated circuit and an antenna. The system may also include at least two first electrical terminals electrically connecting the primary RFID tag to the switch, and at least two second electrical terminals electrically connecting the secondary RFID tag to the switch.
