CurrencyBrazil's unit of currency is the Real, abbreviated BRL, or just R$. Coins are R$0. 05, R$0. 10, R$0. 25, R$0. 50 and R$1. Bills come in the following denominations: R$2 , R$5 , R$10, R$20, R$ 50 and $100. Foreign currency such as US Dollars or Euros can be exchanged major airports and luxury hotels (bad rates), exchange bureaus and major branches of Banco do Brasil (no other banks), where you need your passport and your immigration form.
Large branches of Banco do Brasil (no withdrawal fees for credit cards) usually have one, and most all Bradesco, Citibank, BankBoston and HSBC machines will work. Banco 24 Horas is a network of ATMs (and also Santander Banks) which accept foreign cards (charging R$ 10 per withdrawal). Withdrawal limits are usually R$ 600 (Bradesco) or R$ 1000 (BB, HSBC, B24H), per transaction, and in any case R$ 1000 per day.
In smaller towns, it is possible that there is no ATM that accepts foreign cards. You should therefore always carry sufficient cash. Travellers' checks can be hard to cash anywhere that does not offer currency exchange.
Be careful using credit cards in Brazil. A safer option is to use cash.
TippingGenerally, Tipping is not compulsory, around 10 % service charges are added to bills at the end. You may choose to ignore it, although is considered extremely rude to do it. In some tourist areas you might be tried for extra tip. Just remember that you will look like a complete sucker if you exaggerate, and stingy and disrespectful if you don't tip. 5-10 Reais are considered good tips.
However, taxi drivers round up the fare as a tip for their services.
