Claim 3:
4. An electronic shelf label system (1), comprising:
shelf edge strips (3) and one or more shelf labels (201-211) fastened thereto, wherein the one or more shelf labels (201-211) are designed such that they can be supplied with energy in a contactless manner, and wherein each shelf edge strips (3) comprises a supply device (401-403) for contactlessly supplying energy to the one or more shelf labels (201-211) fastened to it and each of the shelf edge strips (3) comprises at least one conductor loop (L), wherein the conductor loop (L), which is a constituent of the supply device (401-403) of the shelf edge strip (3), is used for emitting a signal, which can be generated by the supply device (401-403) during a time period when the signal is present, for the purpose of the said supply of energy to the one or more shelf labels (201-211) positioned on the shelf edge strip (3) in a manner corresponding to the conductor loop (L);
wherein the one or more shelf labels (201-211) comprise a rechargeable long-term energy storage device (13H);
wherein the one or more shelf labels (201-211) are designed for storing the err transmitted to them from the supply device (401-403), with the aid of the signal in the long-term err storage device (13H), and also for using the err stored in the long-term err storage device (13H), for their operation outside of the time period where the signal is present;
wherein at least one of the one or more shelf labels (201-211) comprises at least one electric data collection consumer (13A-13E), which causes electrical power consumption outside of the time period where the signal is present, and the at least one of the one or more shelf labels (201-211), which comprises such a data collection consumer, covers the power consumption of the data collection consumer of the at least one of the one or more shelf labels (201-211), outside of the time period where the signal is present, with the aid of the electrical energy stored in the long-term energy storage device (13H);
wherein in addition to emitting the signal for the purpose of energy supply, the supply devices (401-403) are designed to set up communication with one or more shelf labels (201-211) with the aid of the signal, and each of the one or more shelf labels (201-211) is designed to analyze the signal and check, during the time period when the signal is present, whether the respective at least one of the one or more shelf labels (201-211) is selected for communication with the supply device (401-403);
wherein each of the one or more shelf labels (201-211) is further designed for first establishing its electrical supply with the aid of the signal when the signal occurs, and for subsequently analyzing the signal and checking whether it is selected for communication with the supply device (401-403), and
wherein the data collecting consumer (13A-13E) is designed to generate and to store data (D) outside of the time period when the signal is present and wherein the at least one of the one or more shelf labels (201-211) comprises electronics, which are designed such that the data (D) stored by the consumer (13A-13E) are available for them during the time period when the signal is present and that these data (D) can be transmitted to the supply device (401-403) during communication with the supply device (401-403).
