Logistics: Apps and Documents: how it works in Brazil — first-hand

Uber payments can be cash-based, but be aware of potential fare adjustments or outstanding charges. In Rio Airport, 99 pickups are on the 2nd floor, while Uber is a short walk from the exit. 2. SIM Cards: SIM cards can be purchased without a CPF at RioSul mall (around 70 BRL), typically at newsstands. 3. Currency Exchange: Airport exchange rates are unfavorable (approx. 3.6 BRL/USD); ATM withdrawals offer better rates (approx. 4.2 BRL/USD with fees). 4. Safety: Areas like Copacabana, Ipanema, and downtown Rio are generally considered safe, even in the evening, provided basic vigilance is maintained and phones are put away promptly after use. 5. Guided Tours: Hiring a guide is recommended for experiences like favela tours or helicopter rides. 6. Food: Explore exotic fruits at São Paulo's Municipal Market. 7. Iguazu Falls: Visit the bird park; a day is sufficient for the Argentinian side, but note the last train schedule to 'Devil's Throat'.

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.

A CPF (Cadastro de Pessoas Físicas), Brazil's individual taxpayer registry identification, is often not critical for short tourist trips (e.g., 2-3 weeks) if no extensive travel within the country is planned and the individual is not engaging in specific financial transactions requiring it. eSIM services (e.g., Airalo) are a viable alternative to purchasing a local physical SIM card for connectivity.

Uber operates effectively; ensure you have a non-Russian version of the app downloaded. Brazilian Reals (BRL) are universally accepted. Non-Russian bank cards (e.g., Kazakh Mastercard) are also accepted for payments. For cash, USD is highly recommended for exchange, though EUR can also be easily converted. Russian-speaking tour guides, including those with vehicles, are widely available.

Aggregator services cost around 3500 RUR. Airport currency exchange rates are poor (e.g., 3.6 BRL/USD). Taxi drivers might offer better informal rates (e.g., 4.7-5.0 BRL/USD). The best exchange rates (5.1+ BRL/USD) are typically found in the city during weekdays.

For transportation, it is recommended to use ride-sharing applications such as Uber or 99 (formerly 99Taxis) for convenient and safe travel.
