The standard business hours are from 9 A.M to 6 P.M. Banks are open from 10 A.M to 4 P.M. Shopping centres are usually open from 10 A.M to 10 P.M, Monday through to Saturday; and on Sundays from 2 P.M to 6 P.M. Pubs and restaurants have flexible hours.

At immigration, non-Brazilian nationals must have their passport, visa (if required) and any other immigration formalities checked. You are advised to contact the embassy in your country to check visa requirements and visa fees. Passports valid for at least six months from date of entry required. Like most airports, in Brazil there are different lines for national passport holders and foreign visitors.

Foreign passport holders should make sure they get their passports stamped and that they retain half of the immigration form they fill in on arrival. Visitors who miss getting their passport stamped or who lose the form will have to get clearance from the Federal Police to leave the country and may have to pay a fine.

In São Paulo, the current is 127 volts (60 cycles) but many of the larger hotels also offer 220 volts. If in doubt, check with the front desk of the hotel or the owner of the house or apartment. Transformers to boost the current from 110 volts to 220 volts are available in most electrical supply
stores.

The Brazilian monetary unit is the real (R$) (plural, reais). There are 100 centavos to the real.

Most major international credit cards are accepted in Brazil. Credit card receipts from stores and restaurants will be priced in reais although you will be billed in the currency of your own country, the official exchange rate having been taken into consideration.

The official exchange rate is published daily in the newspapers and can also be obtained at Brazil’s Central Bank website

The US dollar is by far the most widely accepted foreign currency in Brazil.
There is also an extensive network of ATMs at which some foreign cash cards can be used, although you should check with your bank before departure that your card can be used overseas.

The Santander website offers a list of agencies where money can be exchanged.

Most hotels in Brazil offer web access and there are cyber-cafes in many of the main shopping centres.

Phone cards are sold in pubs and newsstands. For long-distance calls, dial zero + telephone operator number + city code + telephone number. To make international calls, dial zero + telephone operator number + country code + city code + telephone number.

In this non-stop city 24-hour services include much more than chemists and locksmiths. Many supermarkets, flower shops and even fitness centres and convenience stores are also open. The following website (in Portuguese) provides a list of some of these 24-hour establishments:

The conference fee does not cover insurance. The organisers recommend that participants take out insurance in their home country to cover pre-journey cancellation for personal reasons and necessary insurance to cover accidents, medical expenses and loss of personal belongings during the visit.

You are advised to contact the embassy in your country to check if special vaccination is needed depending on the area you plan to visit.

Tipping in Brazil is typically not expected nor given. Obviously, if someone provides a typically good or special service, you might consider a bit extra. 

At almost all restaurants and bars, a standard "Serviço" service fee of 10% is included as a line item at the end of the "conta" or bill.  It is not expected to surpass this amount. It is always clearly identified this fee is not obligatory, but it is hardly expected you pay it.

The organisers cannot accept any liability for damages and/or losses of any kind which may be incurred by the conference participants or by any persons accompanying them, both during the official activities and the excursions. Participants take part in all tours and events at their own responsibility
