UHF-HF RFID integrated tag for moving vehicle identification

Radio Frequency Identification (RFID) is an emerging technology which finds useful applications in many practical areas such as automatic identification and object tracking, supply chain integration, security access to controlled areas, health care and bio-engineering [1]. Due to high flexibility of the RFID systems, in addition to the typical applications mentioned above there is a growing interest in non conventional applications such as the identification of moving vehicles for road-toll and access control purposes.
