Currency and Banknotes in Brazil: real experience from chats

Russian 'Mir' cards are not accepted in Brazil, nor are Russian cards generally accepted in countries like Kazakhstan. While credit/debit cards are widely used, carrying some cash is advisable for smaller purchases or in places where cards might not be accepted. Exchanging currency at the airport often yields unfavorable rates; local exchange bureaus ('cambio') may offer better rates but operate primarily on weekdays. Uber is noted as a cost-effective option for transportation compared to other services, which can be as expensive as in Moscow or higher.

When exchanging USD, newer bills (blue series) fetch a better rate than older green ones. Near Foz do Iguaçu, crossing to Paraguay (Shopping Paris) often provides better exchange rates.

Use local 'Cambio' offices in the city for better rates. When bringing USD, prioritize 'blue' 100-dollar bills (new series); older bills may be subject to a discount of up to 20% at exchange points.

Advises exchanging currency in the city or, preferably, purchasing Brazilian Reals in Russia before departure for a better rate. Mentions a specific exchange office in St. Petersburg (Ligovsky Prospekt) where Reals were available.
