The rack (100) comprises: on at least one wall (105), at least one antenna (110) comprising at least two coplanar loops through at least one of which current flows in the clockwise direction and, simultaneously, through at least one other loop, the current flows in the anticlockwise direction, a signal generation circuit (115) to generate signals transmitted by each said antenna, to generate an electromagnetic field, and a circuit (115) for reception of signals modulating said magnetic field. Preferably, the rack comprises products equipped with electronic tags and paper labels, said electronic tags positioned on one side of the product opposite another side of the product bearing a paper label. Preferably, the rack comprises at least one opening, the circuit for generation of signals transmitted by the antennae being slaved to closure of said opening to read the electronic tags after at least one time interval predetermined according to the time of said closure.
