As a note, this is slightly incorrect:

> The Indian model is inspiring others. Brazil’s Pix, which facilitates bank-to-bank payments with a small fee, was launched in November 2020. It now accounts for some 30% of Brazil’s electronic payments (credit and debit cards take up around 20% each)

In fact, Pix is free, which is the main reason why the Brazilian population adopted it so widely and so quickly. Before Pix, you'd always have to pay a significant fee to make bank transfers, and they could end up taking a whole day to go through.
