The exchange rate system has been liberalised and foreign currency is freely available through authorised dealers including banks and Forex Bureaux.
Cash is exchanged at a more preferential rate than are travellers cheques.
Check with your credit card company for detail of merchant acceptability and other services which may be available. The import and export of local currency is limited to amounts which have previously been permitted to be taken out of the country. Unused local currency can be re-exchanged on proof of authorised exchange, and visitors are advised to retain all currency exchange receipts.
