The unit of currency is the Tanzanian shilling (Tsh) and there are no smaller denominations. It’s best to carry as little cash as possible when travelling to avoid further inconvenience if anything should be lost or stolen.
That said, major currencies (like the US Dollar, the English Pound, and the Euro) are easily changed in large towns, although US Dollars are sometimes preferred.
Forex bureaux offer faster service than banks and although the exchange rates are only nominally different, the bureaux usually offer a better rate on travellers’ cheques. Standard Chartered banks around the country have ATM machines that allow you to withdraw cash from your VISA card and Barclay’s Bank ATMs allow you to withdraw on both VISA and MasterCard accounts. Credit cards are accepted only at major lodges, hotels, and travel agents.
