Electronic Shelf Label (ESL) — Digital Wireless Price Tag, Multi-Size Series

This electronic shelf label (ESL) series replaces paper price tags in retail stores. Each tag uses an e-ink screen that stays visible without backlight and consumes power only when refreshing, so the battery lasts for years. Price, promotion, unit and barcode/QR information are updated wirelessly from the backend system, letting staff change prices on hundreds of shelves at once instead of reprinting paper labels. The multi-size lineup, black/white and color promo versions fit wine shelves, fresh-food sections and general merchandise, reducing labor cost and eliminating outdated-price errors for faster, cleaner store operation.
