Whether utilised in the food sector, fashion and footwear stores or pharmacies, electronic shelf labels are found in every retail branch and segment. Electronic shelf labels are no longer used just to display prices. Today they play a more enhanced role, providing employees and customers alike with diverse information. They save time in the purchase decision and contribute to an improved shopping experience. The electronic shelf labels clip securely into place on the selected display system. Connected to the power supply in the concealed 3V rail, they do not require any batteries. There are no limits to the available options, enabling the display of product descriptions, graphics, photos, QR codes and barcodes alongside the price. Different apps can be connected with ESLs. This makes it possible to find a product quicker. The product in question is selected in the app and the LED lamp on the ESL lights up immediately.
