Digital Shelf Label (DSL) is an advanced electronic labeling solution designed for the retail industry. It provides many practical functions and is a perfect replacement for traditional paper price tags. First, DSL enables real-time price updates. By connecting with the retail management system, businesses can easily update product prices and promotional information, which is instantly reflected on the label. This eliminates the hassle of manually changing price tags and avoids price confusion caused by human error. Secondly, DSL provides more display space for displaying additional product information. Merchants can display detailed information such as brand, model, origin, etc., so that consumers can understand products more clearly, so that they can make more accurate choices when shopping. Additionally, DSL offers a personalized shopping experience. According to consumers’ preferences, it can display customized promotions or coupons to stimulate their desire to buy. In addition, DSL also contributes to environmental sustainability. Since it is reusable and does not require paper labels, it reduces paper waste and is more environmentally friendly. In conclusion, DSL is an innovative tool for the retail industry, providing fast, convenient, personalized and environmentally friendly labeling solutions. It improves the operational efficiency of enterprises and improves the shopping experience of consumers.
