Thanks! Yeah, I think in the case of the QR code for the street performer, he's just best off with a lightning address, right? I've actually sold a handful of cds after shows with lightning address just because I can verify in person. Here, I'm focusing more on paywall specifically for something downloadable. I might be hearing your suggestion wrong though.

And yeah, I totally agree that it'd be great if I could keep this all self contained. That would lower the barrier to entry astronomically. I had a friend already who put in his blink account ID instead of wallet ID on the wallet linking page. However, I'm still afraid building a whole wallet is too risky for someone at my level of technical knowledge...at least for now...
