American Express, Diners Club, MasterCard and Visa are accepted. Credit cards are not usually accepted at petrol stations, so bear this in mind when you visit the ATM. Setting aside an emergency petrol cash fund is a good idea if you’re planning to drive.
Although ATMs can be found in most towns, it’s worth making sure that you’ve got enough cash handy at all times, as towns can be few and far between. Make sure you notify your bank of your travel plans before you go: Namibia is among the countries that trigger an automatic account freeze (fraud protection) if you fail to tell your bank beforehand.
To avoid additional exchange rate charges, take traveller's cheques in US Dollars or South African Rand. In general, you can expect a better exchange rate for traveller’s cheques than for cash.
