<p>The invention relates to a system for sensing an RFID tag (2a) allocated to at least one scanning position (Pij) comprising RF sensors (1A-1H), at least one which RF sensors (1A-1H) is in a detection state for detecting the RFID tag (2a) within sensing regions while the other RF sensors (1A-1H) are in a passive state, which sensing regions are arranged such that each of the sensing regions covers at least one scanning position (Pij), wherein the RF sensor (1A-1H) in the detection state transmits a first RF signal at a first frequency and the other RF sensors (1A-1H) in the passive state are resonating at a second frequency that is different from the first frequency. In this way the cross-talk or mutual influence between the RF sensor (1A-1H) that is in the active state and the RF sensor or sensors (1A-1H) that are in the passive state is substantially reduced.</p> |
