In Tanzania the currency is the Tanzanian shilling. In Kenya, the currency is (you guessed it) the Kenyan shilling. You can find the current exchange rates here for the Tanzanian shilling and the Kenyan shilling.  But don't worry, almost anyone will take US dollars if you need them to.  I've even tipped porters and guides with American Express Travelers Checks when really desperate. tanzanian shilling kenyan shilling

Banks and ATMs

There are banks in the larger cities like Moshi, Arusha, and Dar es Salaam. You can exchange your traveler's checks at banks that have a currency exchange section or at most hotels. But don't expect the same lightning speed you see here in the US. If you want to use an ATM to get Tanzanian shillings, you'll need to have a card that has the VISA symbol. There are 2 ATMs in Moshi, but they only accept VISA. There are about 4 in Arusha, but again they only accept Visa. There is only 1 place that we know of where you can use your MasterCard or American Express to get cash in Arusha (none in Moshi). The "ATM" is actually a person at the Arusha Resort in Arusha and they charge a higher rate. But it's there if you need it.

Credit Cards

Credit cards are accepted at only some of the large hotels and tourist shops, but are not widely used in Tanzania. It's probably best to assume that you won't be able to use your credit card in many places.

A Word on Pickpockets

The people of Tanzania are very friendly and helpful. However, Africa in general is pretty famous for pickpockets and thieves. We recommend you don't carry all of your money, and only have a few small bills in your pocket for buying things like water and snacks. Be assured that if you take out a big wad of money people will notice. Pickpockets have also been known to reach into shirts to try to get money out of money belts, especially on crowded buses.  Don't be paranoid, just aware.
