Radio Frequency Identification (RFID) technology enables detection and recognition of objects associated to univocal identification codes. A typical RFID system comprises an RFID reader linked to one or several antennas that interrogate the tags within its detection range. A dedicated computer application manages the data logging and processing. Several frequency bands are assigned to RFID, from HF up to microwaves. At present, the UHF RFID tags are preferred for a wide range of applications because its unit cost is the lowest. The usable UHF band ranges from 860MHz to 960MHz, allocated in three different intervals for different world regions by the International Telecommunications Union (ITU).
