- you can now use the chat interface to see and add messages to be written
- tap the phone to the sticker again to write new messages to the nfc
to setup a new messageboard on a passive nfc device:

- ensure phone has NFC and is enabled
- visit the webapp https://in05-network.github.io/msgboard/
- click button (if present) and approve enable nfc permission
- touch phone to nfc. nfc must be away from other nfcs, must be flat, etc
