it would be nice if someone could send a message (on nostr?) to me and I could go to any location that offers the ability to look up those messages by entering some data (12 words?)

maybe I could go to a "nostr message ATM" that lets me quickly receive any potential important messages that I missed while away from home, without having to bring my phone with me, and it debits from my Primal/etc account

obviously there would need to be a way to ensure that "ATM" doesn't use location data tied to the nostr ID

I'm sure someone could think of a better way to do this without tracking
