The new user cases with LN are amazing, thanks for sharing.

Amazing
what happens when someone creates an invoice and brings near the ring unexpectedly? the invoice gets paid?
Yes, it gets paid. You can set invoice limits (e.g. max 1000 sats), time limits (wait 10 minutes before allowing next payment) or maybe in future some smarter solution.
E.g. it would be cool if it only allows you to pay to your allow list of businesses. And maybe that Allowlist could be based on Nostr business profiles that you and your friends follow. So the invoice would just need to include npub and then the rest can be handled in your app.
I guess what I'm saying is that this is solvable and super cool 😎
So an NFC enabled app can ask your ring to receive sats and the ring signs? And you holding your phone normally is enough for any background app to do that? What can you do if you bleed 2000 sat every odd hour? How long until you really it's actually one of those 500 apps on your phone? And once you have your phone under control, how long until door-knobs bleed sats?
I mean it's cool and sure, you can set limits but if you set those limits too high and many people use such a device, bleeding will happen everywhere. If you set the limits too low, there goes your convenience.
I see people posting things like this and I can’t get my umbrel to reliably stay connected or running for longer than a day
Ok, wow, this is rad.
This is sweet. Can it be used for 2FA like a yubikey or is it wallet specific?
