>And also, why Master and Visa haven’t came with a solution where they integrate with all of that and innovate?

There are a lot of people who integrate with them. The issue is that anyone who does so must comply with the PCIDSS. Most hobbyists cant stretch that far and use intermediaries.

>This idea that all they do should be de facto standard for the whole world is so démodé.

I dont know what Brazil's issues were, but Visa and Mastercard show up, they integrate with terminal providers directly and indirectly, and they bring a battle tested data security standard with them. Compared to other industries they are basically self regulating, and in some countries they adopt the PCI DSS into law.
