<p>The invention concerns a method comprising the following steps: transmitting in the form of a query (14) a signal with a first set of antennae of the vehicle towards the badge, optionally a reply (16) from the badge to said first query, transmitting in the form of a query a signal (18) with a second set of antennae of the vehicle to the badge, optionally a reply (20) from said badge to said second query. In case of reply (16) from the badge to the first query (14), the badge stores for a predetermined time interval the fact that it has replied to the signal transmitted by an antenna of the first set. The possible reply (20) made to the second query (18) includes, as the case may be, an information indicating that a reply has already been transmitted in response to a query from the first set of antennae.</p> |
