(I haven't tried PIX so not sure) but UPI is really great too and I think that Pix is similar to UPI and UPI was launched by India nearly 4 years ago than brazil.

Anyways, one of the things that I am interested about in payment systems is say creating cross-payments between Pix,UPI and Wero.

UPI is already there for a few countries and there are more trials which are happening and my brother was a bit involved in trying to add UPI to london. (I think it was some efforts by his college perhaps, I am not sure completely.)

For India, the largest points are remittances and for other nations, it gives a really well built payment system and integrates it to more economies.

UPI is accepted in seven countries: Bhutan, France, Mauritius, Nepal, Singapore, Sri Lanka, and the United Arab Emirates (UAE).
