Relay helps you work with NFC tags confidently. Before writing, the app checks whether the tag is writable and whether the payload fits. If something cannot be written, Relay shows a clear reason instead of failing silently.

Use Relay to create smart desk tags, guest Wi-Fi tags, event links, product information tags, contact cards, automation launch tags, and other quick tap actions.

Tap a tag. Read what is inside. Write what you need.
