4.2-inch Black, White, Red, and Yellow Four-Color Display with Bluetooth and Customization Support

Our electronic shelf labels are different from those of our competitors, as we have endowed them with new functions and value.

No longer just a simple price tag in supermarkets, it now doubles as an advertising POP machine. By utilizing the screen's blinking effect, it grabs customers' attention. What’s more, it allows you to edit advertising messages online. Unlike traditional POP machines that can only display fixed messages, now you have the freedom to display whatever you want. This is a revolutionary step in electronic shelf labels.

With our API interface provided to third parties, it can integrate with any application system. Take advantage of our years of hardware expertise to ensure seamless integration with your system. In fact, electronic shelf labels are no longer just price tags.

Take this 4.2-inch electronic shelf label as an example. Equipped with monochrome, tri-color, or four-color e-paper display, its vivid colors can adapt to any retail scenario. It supports text, promotional messages, QR codes, or barcodes, and is reusable without the need for paper. It can also be applied in various scenarios beyond retail, such as logistics management. Here’s an example scenario: Imagine every city’s marathon finish line equipped with a base station. As marathon enthusiasts wearing this card approach the finish, the content on the card gets updated, displaying your personal information and race results. You can then upload this image to a mobile app, turning it into a fun conversation piece with your friends. Wouldn't this make for an unforgettable marathon experience? If you're looking to create something similar, please contact us — we have ready-made solutions available.
