Abstract: The present disclosure provides methods and apparatuses for loading program data on to an unpowered electronic device, such as an RFID tag that includes volatile memory. Initially, the tag is unpowered. Thus, the volatile memory in the tag will not have any stored data. In order to load data into the memory of the tag, a reader can power the tag wirelessly. The reader includes an antenna configured to transmit electromagnetic radiation and receive backscatter electromagnetic radiation. The reader also includes a processing unit. The processing unit is configured to analyze the backscatter electromagnetic radiation. The processing unit may analyze the backscatter radiation to determine a supply voltage induced in the tag. In response to the induced voltage being greater than a threshold, the processing unit may alter the transmitted electromagnetic radiation to communicate tag data.
