Security on RFID technology

RFID (Radio Frequency Identification) systems are emerging as one of the most pervasive computing technologies in history due to their low cost and their broad applicability. Latest technologies have brought costs down and standards are being developed. Actually, RFID is mostly used as a medium for numerous tasks including managing supply chains, tracking livestock, preventing counterfeiting, controlling building access, and supporting automated checkout. The use of RFID is limited by security concerns and delays in standardization. This paper presents some research done on RFID, the RFID applications and RFID data security.
