The Rwandan franc (RWF) trades against most international currencies at a favourable rate. Major international credit/debit cards (for instance Master and Visa) can be used to draw local currency at 24-hour ATMs in most cities and towns, but not in the national parks. Many vendors do not accept cards, however, so it’s a good idea to carry a few hundred dollars’ worth of hard currency cash as a fall back. The Euro is the most readily accepted hard currency bit US dollars and to a lesser extent British pounds sterling are also widely recognised.
