Performance development of a high-speed automatic object identification using passive RFID technology

The operation of an RFID (radio frequency identification) system in fast identification applications is researched and analysed in this paper. The identification velocities are measured with two applicable measurement systems. In addition, a method to achieve faster identification velocities is presented and analysed. Measurements are based on MIT (Massachusetts Institute of Technology) auto-ID Lab´s Class I passive RFID system specification. The results indicate that single object identification is achievable up to velocities of 40km/h. Multiple object identification accuracy depends on the number of objects. The method presented in this paper enables the velocity of moving objects to be increased together with improvement of the effectiveness of the application identification process. The goal of the research is to find the achievable identification velocities of a passive RFID system and in addition, a method to achieve faster moving object velocities and further assist several high-speed identification application areas.
