What is Banco Central do Brasil?
In short
Brazil's central bank, the authority that authorises and supervises the banks and payment firms behind the cards in this comparison.
Banco Central do Brasil is Brazil's central bank, the authority that authorises and supervises banks and payment institutions in the country. It is the regulator recorded against FinanZero, Meliuz, Neon and PagBank, which matters when you compare card accounts because a register entry shows who is allowed to hold and move your money. Before you apply for a prepaid or debit account with a Brazilian provider, check that the company appears under this authority and keep the register details with your own records. A name you recognise beats a fee you cannot check.
