Abstract
The invention relates to a near-field communication surface intended to communicate with at least one electronic tag. The surface comprises a plurality of antennas, each antenna having a position along an axis, a circuit for reading electronic tags that is connected to said antennas in order to supply them with power and communicate with said electronic tag, and a processing unit controlling the antennas and the circuit for reading electronic tags. The processing unit is configured to activate just one antenna at a time and the reading circuit in order to communicate with said at least one electronic tag, and to locate a position of the electronic tag along the axis according to a number of responses or to a response time from the electronic tag. The invention also relates to the locating method.
