<p>The invention concerns a device for displaying prices electronically on shelves (1). To improve the operating safety, and to reduce the radiated field strengths, it is proposed that the transmitting elements (6) near the display units (4) are moved to the edges of the shelves (1), that the components (13) of the display units (4) receive the energy which is radiated by the transmitting elements (6) inductively, and that the control transmitter (3) applies an alternating current to the transmitting elements (6) in the pauses (26) between the data packets (25), and charges the current sources (15) of the display units (4). <IMAGE></p> |
