This 2.7" passive NFC-powered e-paper module is designed for low-power, cable-free display applications. It harvests energy directly from an NFC reader or compatible smartphone, eliminating the need for batteries or external power supplies. Update screen content wirelessly via NFC. Simply hold an NFC-enabled device near the module to refresh images, text, QR codes, prices, or tags. No physical connection is required, making deployment and maintenance simple and efficient. The passive e-paper display consumes ultra-low power and only requires energy during content refresh. Once updated, the image remains on the screen without continuous power, enabling long-term, maintenance-free usage in various environments. Perfect for electronic shelf labels, price tags, product information cards, logistics labels, conference badges, and smart signage. The 2.7 inch size offers a clear, readable display area while remaining compact and easy to mount.
