Abstract (en)
[origin: WO2021129932A1] A method for operating an electronic shelf labelling system (1), the system having shelf labels (203) secured on shelf edge strips (3), wherein: the shelf labels can be contactlessly supplied with energy, the shelf edge strips have a supply device (21) for contactlessly supplying energy to the shelf labels secured on same, and the shelf edge strip has at least one conductor loop (L), the conductor loop being a component of the supply device of the shelf edge strip, and the conductor loop is used to emit a signal, which can be produced by the supply device, for the purpose of the aforementioned supply of energy to shelf labels positioned correspondingly relative to the conductor loop on the shelf edge strip; and, according to the method, the aforementioned signal is produced by means of the supply device and is emitted via the conductor loop, and the shelf label positioned correspondingly relative to said conductor loop stores electrical energy, which is transferred from the supply device to the shelf label by means of the signal, in a rechargeable long-term energy storage device and uses it for operation outside of the period of the presence of the signal.
