Abstract:
Systems and methods are provided for using a rechargeable electronic sign label. Exemplary embodiments include an electronic sign label electrically coupled to a capacitor and an RFID tag. One or more RFID readers are in communication with the RFID tag. The RFID tag is configured to determine when the charge of the capacitor is below a threshold value, and in response transmit a message to the RFID readers. At least one RFID reader transmits a signal to the RFID tag that includes an instructions to charge the capacitor. An antenna of the RFID tag may be electrically coupled to the capacitor to allow the capacitor to charge based on the energy collected by the RFID tag antenna.
