Description

		2.9-Inch E-Paper Price Tag with Tri-Color or Four-Color Display, Bluetooth, and Customization Support
		Our electronic shelf labels redefine the role of traditional price tags. Beyond just displaying prices, they double as dynamic advertising POP machines. With a blinking effect to grab attention and the ability to edit messages online, they offer unmatched flexibility compared to fixed-message POP displays. Seamlessly integrating with any system via our robust API, these labels adapt to diverse needs. The 2.9-inch e-paper display, available in monochrome, tri-color, or four-color options, delivers vivid visuals for text, promotions, QR codes, and barcodes. Reusable and paper-free, they excel not only in retail but also in logistics and other industries.
