From wikipedia:

Pix is an instant payment platform created and managed by the monetary authority of Brazil, the Central Bank of Brazil (BCB).[1] It enables instantaneous payments and transfers in Brazilian real, even outside banking hours or on weekends, with no fees.

Pix was announced in February 2019 and became fully operational on 16 November 2020. It rapidly became the main payment system in the country; by July 2024, Pix transactions had reached almost R$2.5 trillion per month, with more than 70% of the country (over 150 million people) actively using it.

It seems like it is not available outside Brazil and their currency, but is wildly successful (70% adoption in 4 years) and anecdotally on other forum discussions I've heard the people like it.

Also from the article itself

"Pix reached 63.8 billion transactions in 2024 — a 52% increase from the previous year, according to a recent survey by the Brazilian Federation of Banks. Pix overtook debit card transactions in January 2022 and credit cards in February 2022; it now dwarfs transactions via credit cards, debit cards, bank slips, wire transfers, prepaid cards, and checks combined."

It seems like a smashing success, and maybe Visa and Mastercard are trying to pressure the government of the USA to get them back on their rails (that they collect fees on for usage.)
