The rial is the official currency of Iran. It is subdivided into 100 dinars, but due to the rial's low purchasing power the dinar is not practically used. While POS terminals are in use in Iran, the country does not participate in any of the major international card networks due to sanctions between it and the United States. Travelers are instead advised to load money onto a local prepaid card account.
The Iranian rial remained relatively stable against the U.S. dollar until late 2011 when it lost two-thirds of its value within two years.

The dinar is the name of the principal currency unit in several countries near the Mediterranean Sea, with a more widespread historical use. The English word "dinar" is the transliteration of the Arabic دينار (dīnār), which was borrowed via the Syriac dīnarā, itself from the Latin dēnārius.
