Abstract

Several RFID Standards allow RFID Tags to be ‘killed’ using a specialised command code. ‘Killed’ RFID Tags should be irrevocably deactivated. In actuality, when a valid kill command is sent to a tag four sections of the tags management data are zeroed causing the tag to enter a ‘fault state’ and thus be ignored by RFID readers. Through the reinitialisation of these four sections to valid values it was discovered that a tag could be resurrected and function normally.
