    摘要: A method and system for identification of an item is provided, wherein the system includes a conveyor belt, a positioning device and a reader operable to receive at least one reading at at least one first antenna from at least one tag attached to the item, the first antenna being adapted to be arranged at a read point along the conveyor belt, 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 (6) of the phase of the signal transmitted by the tag (5) and perform a data processing of the phase measurements whereby the identification of the item (2) is accomplished.
