A method for implementing a software-based (SB) radio frequency identification (RFID) tag is disclosed. The method comprises storing first RFID identity data in a memory of the SB RFID tag, storing second RFID identity data in the memory of the SB RFID tag; and receiving via an antenna coupled to the SB RFID tag an RFID interrogation signal from an RFID reader and, in response determining by a processor of the SB RFID tag a status of an RFID identity selection criterion, selecting one of the first RFID identity data and the second RFID identity data, based on the status of the RFID identity selection criterion; and sending the selected one of the first RFID identity data and the second RFID identity data to the RFID reader via an antenna coupled to the SB RFID tag.
