Radio Frequency IDentification, a non-contact data storage and access technology which reads or writes information in RFID tags by receiving radio frequency signals through RFID readers. RFID tags can signal their existence, uniqueness, locality and other user-preferred information through wireless information transfer via radio waves. This paper describes the technical fundamentals of RFID systems and the associated standards. Specifically, it addresses the security and privacy aspects of this relatively new and heterogeneous radio technology. It relates the security requirements, threats and the implemented mechanisms. Then the current security and privacy proposals and their enhancements are presented.
