⚠️

IMPORTANT: Reader & APP Compatibility – Do Not Mix
DMN029AB / DMN029AW series labels must be used with the dedicated DMN‑series APP. Using GDN‑series firmware or readers will cause communication errors and refresh failures.

📌 Software & Firmware: Use the APP version specified on your product page. DMN / GDN apps are NOT interchangeable.

📱 NFC Usage Note: For optimal performance, avoid placing the badge directly on metal surfaces, as metal may block or weaken the NFC signal.
