Abstract: A method includes providing a power supply package (PSP) that includes a power supply, an RFID tag, and a power switch, where a control terminal of the power switch is coupled to an output terminal of the RFID tag, and load path terminals of the power switch are coupled between an output terminal of the PSP and a first terminal of the power supply, where a control register of the RFID tag is pre-programmed with a first value such that the RFID tag is configured to generate a first control signal that turns off the power switch; receiving, by the RFID tag, a second value for the control register of the RFID tag; and writing, by the RFID tag, the second value to the control register of the RFID tag such that the RFID tag is configured to generate a second control signal that turns on the power switch.
