How to use NFC cards for logging into Nostr, and for giving out to grow your Nostr personal network.
Discussion
You can store and share VCards the same way, and e.g. Android will automatically offer to create a new contact in your address book when scanning that. I think maybe we should agree on a standard field for adding npubs to VCF?
Great idea. I don't think wide agreement is necessary. You should propose one!
