The purpose of this paper is to review RFID systems and its various components infrastructure. The components and features are still under research and being integrated in existing systems to create a marketable and potential new system. To achieve higher performance; low cost, low power RFID tag with efficient anti-collision technique which provides a large throughput and flexible security mechanism is required.
