Radio FREQUENCY identification (RFID) is a rapidly developing technology which uses RF signals for automatic identification of objects. Although the first paper on modulated backscatter (basic principle of passive RFID) was published in 1948 [1] it took considerable amount of time before the technology advanced to current level [2]. Now RFID finds many applications in various areas such as electronic toll collection, asset identification, retail item management, access control, animal tracking, and vehicle security [3]. Several standards of RFID systems are currently in use (ISO, Class 0, Class 1, and Gen 2).
