Abstract: In this paper, the performances of radio frequency identification (RFID) and electronic product code ™ (EPC) Class1 Gen2 devices applied to commercial products are measured and analysed. In particular, a methodological approach is developed in order to measure the performance of the RFID system under item-level tagging in three different scenarios: (i) static case test, (ii) conveyor case test and (iii) pallet test. The tests assess the performance of RFID systems by means of commercial products, in a real production environment under typical working conditions. The combined influence of different parameters has been investigated. Results show that the RFID technology has reached a satisfactory level of reliability, which allows its infield application.
