Brazil's government-run payments system has become dominant

I've been living in Brazil for the last 20 years.

Pix revolutionised the way we transact in Brazil. I've used Pix to pay for things that cost only cents, and I have a friend who bought her house using Pix. The system just works for any transfer amount. And it's so easy to use.

Its speed is truly baffling, and so is its reliability. Never have I failed to make a Pix payment because of downtime. I never cease to be amazed by how fast money arrives in my Brazilian account when I make a withdrawal directly from my EUR wallet on Wise. I receive a push notification from my Brazilian bank before Wise finishes running the animation of confirmation of withdrawal. It's like magic.

And it's so widespread that nowadays I don't even question whether someone accepts Pix. When I get in a taxi, no matter how old the driver is, it's certain that they take (and prefer) Pix.

I've even had homeless people ask me for Pix instead of change on multiple occasions.

Cryptocurrencies don't stand a chance.

The world needs to implement Pix. I truly believe that is a system which can replace SWIFT with just a intermediary, with a virtual currency that exchange rate between the 2 countries in the operation, this way the world can have a freedom outside dollar and really fast transactions.

Europe has SEPA payments. They are very fast and reliable, and separate from Swift.

I have only come across SEPA as a means of making transfers between bank accounts. Can it be used for payments too (e.g. instead of a credit card)?

It is also single currency - Euro only, right? Swift is global.

Dealing with many currencies and laws (e.g. countries with capital controls) is very complex.
