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.
