With the increasing usage of RFID systems and their potential in a range of common applications especially medical related fields, it is important to investigate the weaknesses of the technology and the potential risks that accompany them. Current RFID standards allow for the use of a KILL command to enable users to effectively switch a tag off. However, it has been demonstrated that this method may be reversed and allow for the recovery of sensitive information as well as allowing a possible avenue for attack. Thus while the concept of a command to destroy an RFID tag is required the current implementation is ineffective.
