The unit of currency is the Rwandan franc (RFr). It is divided into 100 centimes. Notes come in RFr100, RFr500, RFr1000, RFr5000 and RFr10,000 denominations. Coins come in RFr10, RFr20 and RFr50.
Tipping is common in the cities these days due to the large international presence. Rwandan salaries are low and a tip of about 10% will be appreciated.
