Security in RFID Systems

Increasing adoption of Radio Frequency Identification (RFID) technology opens a new frontier for data threats and data security measures. Broadly speaking, RFID includes a full spectrum of wireless devices of varying capabilities, power, and sophistication-including ExxonMobil SpeedPasses, vehicle immobilizers, Electronic Product Code (EPC) tags, and more. RFID tags are small, wireless devices that emit unique identifiers upon interrogation by RFID readers, which emit powerful electromagnetic fields and "read" tag information.
