Lots of countries around Brazil are taking pix. Argentina, Uruguay, Paraguay.

And you can totally expand the idea. The fact that you need national id for pix doesn’t mean the idea “doesn’t scale.” It means the current implementation of it is not focused on use by visitors.

I really don’t understand what you’re getting at, it seems like a pretty narrow view of the possibilities.

Meanwhile US citizens are using paper (cash and cheques) for lots of transactions. Or one of the big credit card corporations.
