When selecting digital price tags (ESLs) for fruit, prioritize IP67-rated waterproof and dustproof designs, as fruit sections often involve moisture, misting systems, or juice leakage. Ensure the display uses E-ink technology for high visibility under bright supermarket lighting and a wide viewing angle (up to 180 degrees) so customers can see prices from any direction. Additionally, look for tags that support multi-color displays (Black/White/Red/Yellow) to highlight promotions or organic certifications effectively.
