Peso (ARS; symbol AR$) = 100 centavos. Peso notes are in denominations of AR$500, 100, 50, 20, 10, 5 and 2. Coins are in denominations of AR$2 and 1, and in 50, 25, 10, 5 and 1 centavos.
US Dollars are accepted in some hotels and tourist centres. Prices in US Dollars are typically marked with US$ to avoid confusion, but sometimes both peso and dollar prices are both preceded by just $, so check if unsure.
Most major credit cards are accepted, but not as widely as in the US or Europe; even some major hotels do not have credit card facilities.
ATMs are available in most cities and have options in English, but it is still best to carry alternative forms of payment as daily withdrawal limits are low and machines don't always work. During national holidays ATMs can run out so it is wise to withdraw in advance.
Foreign tourists who are not resident in Argentina can no longer pay for tourism-related services (air tickets, bus travel, hotel rooms, all-inclusive tours etc) in Pesos. These services must be paid for with foreign credit and bank cards, money transfers (in foreign currencies) from abroad, in cash with foreign money (eg US Dollars) or with cheques from foreign accounts.
It is advised to bring traveller's cheques in US Dollars; these can be exchanged at banks, bureaux de change and some hotels. However, it is often difficult to exchange these in the smaller towns.
Visitors to Argentina can import up to US$10,000 or its equivalent without having to declare. The export of foreign currency for amounts higher than US$10,000 or its equivalent in other currencies is prohibited. Minors aged between 16 and 21 years old can exit Argentina with a maximum of US$2,000 or its equivalent in other currencies, and minors under 16 years old with a maximum amount of US$1,000 or its equivalent in other currencies.
Foreign currencies can be exchanged in banks and authorised cambios (bureaux de change), which are available in all major cities. Visitors should be aware that due to the instability of the peso, there is a large 'blue' market for dollars, which provides a much more favourable exchange rate of exchange. Whilst it is illegal to exchange currency in from these unauthorised money lenders, the practice is so common so as to make the black market rate the de facto rate.
