Abstract: Provided is a system for identification of an item, wherein the system includes a conveyor belt, a positioning device and a reader operable to receive at least one reading, wherein the positioning-device is configured to retrieve a first position of the item) at a first time instant before the first antenna and a second position of the item at a second time instant after the first antenna, the first and second time instants defining a time window, wherein the reader is configured to extract from each reading retrieved by the first antenna a measurement of the phase of the signal transmitted by the tag and perform a data processing of the phase measurements, whereby the identification of the item is accomplished.
