Are credit cards widely accepted and safe to use locally? Are ATMs common and do you recommend using them? Are they safe to use?
Credit cards are very commonly used; even delivery guys come with their card reader. You generally want to use an ATM associated with a known bank, and ATMs inside gas stations are generally OK if they're tied to a known bank. If you don't recognize the bank, don't use it. - Aug 2020

Banco de Brasil and HSBC seem to work fine. Most restaurants and stores take international credit cards as well. There have been some cases of consulate workers having numbers stolen. - Jan 2011
