Re:Brazil's Pix Payment System Faces Pressure from Visa and Mastercard
on Friday May 08, 2026 @09:46AM (#48063082)
Other countries adopting it is already happening. I live in Bolivia, and a few events made QR payment systems widely used across the country. I have family in Peru, and it is a similar case with Yape, another QR payment system. In Bolivia, fintech companies also offer integration with Pix in Brazil without the need for a CPF to send and receive payments. Since we are neighbors, this is very handy.

Re:Ask HN: Do you search for podcasts episodes based on a topic?
on Thursday February 14, 2019 @12:26PM (#19163754)
Hi
I sort of do the same, when I read a book I usually look for podcast interviews or book reviews about the book, and as a software engineer when I want to pick up a technology to learn before start following tutorials I look for podcast about the particular technology this is great because people is forced to describe the technology(framework/library/utility) in speaking words.
