Currency: The currency in Peru is the Nuevo sol (‘new sun’) and comes in bills of S10, S20, S50, S100 and (rarely) S200 and is divided into 100 céntimos, with copper-coloured coins of S0.05, S0.10 and S0.20, and silver-coloured S0.50 and S1 coins. There are also bimetallic S2 and S5 coins with a copper-coloured centre inside a silver-coloured ring.
When receiving local currency, always ask for small bills (billetes pequeñas), as larger bills are hard to change in small towns or for small purchases. The best places to exchange money are casas de cambio (foreign-exchange bureaux). Most tourist orientated businesses accept US dollars, although the Euro is being increasingly accepted. Other hard currencies can be exchanged, but usually with difficulty and only in major cities and tourist centres.
All foreign currencies must be in flawless condition and do not accept torn money, as it will likely not be accepted by Peruvians. It is best not to change money on the street as counterfeits are a problem.
Credit cards: The most widely accepted cards are Visa and MasterCard. ATMs are available in big cities, upmarket hotels, and tourist areas.
Tipping: In restaurants, an 18% service charge is included in the bill if you are paying by credit card. If you are paying in cash, there is no fee; tip 5%- 10%.
