Abstract (en)
[origin: WO0209022A1] There is described a multiple tag interrogation system (10) for simultaneously interrogating a plurality of tags (200, 210, 220) each including at least two interrogatable features (600, 610, 620) the system (10) comprising a receiving region (50) for receiving the tags (200, 210, 220), interrogating means (100, 110, 150, 160, 170) for interrogating the tags (200, 210, 220) and processing means (40) to determine at least information carried by the said at least two interrogatable features (600, 610, 620) of each tag and spatial position characteristics of the said at least two interrogatable features (600, 610, 620) therein and to identify the information carried by individual tags (200, 210 220) on the basis of the spatial characteristics of the interrogatable features (600, 610, 620). The invention also includes the method of multiple tag interrogation.
