NFC tags on hives

On the hive card, under “Identification”, look for the “RFID tag” heading, tap “Scan tag” and hold the phone against the tag. The app links it to this hive and shows “Tag attached successfully”. “Rescan” and “Remove tag” change or clear the link.

After that, holding the phone against the hive is enough to open its card. It works even when the app is closed: the tag launches it and goes straight to the right hive.
