Brazil ended with a third system: Pix. It boils down to the following:
The "key" in question can be your cell phone number, physical/juridical person registre number, e-mail, or even a random number. You can have up to five of them.
Regarding dynamic codes, it's also possible to generate a key or QR code that applies to a single transaction. Then the value to be paid is already included.
Frankly the system surprised me. It's actually good and practical; and that's coming from someone who's highly suspicious of anything coming from the federal government, and who hates cell phones. [insert old man screaming at clouds meme]
This sounds very reasonable and not unlike payment apps I use, like Tikkie or Klarna
Brazil's PIX is revolutionary, really. It's instant 24/7 transfers that don't depend on which bank you're using and does not need a third party app. Pretty much if you have a bank account, you already have PIX.
