ABSTRACT:
A closure includes a closing member for sealing an opening of a pressurized container. The closing member may include a passive electronic sensor coupled thereto that includes a status register that may be readable by, for example, a RFID reader. The status register is responsive to a pressure change in the pressurized container caused by an insertion of the closing member into the opening or an extraction of the closing member from the opening. The status value in the status register indicates whether the pressurized container has been tampered with. An identification register may include a pressurized container identification encrypted with the private key of the manufacturer, which can be decrypted for comparing to identification on the pressurized container to identify tampering.
