The Jordanian dinar (JD) is the official currency of Jordan. Piasters are the equivalent of cents/pence and you will often hear people referring to piasters (i.e. 1 dinar is equal to 100 piasters).
Banknote: 1, 5, 10, 20 and 50 dinars.
Coins: 5, 10, 25, 50 piasters.
1 USD = 0.708 JD (JD IS PEGGED TO THE USD)
Best rates are found in banks and exchange shops, although the ones at the borders and airports will add commission.
Travellers' cheques will be charged a commission (around 3–8 JD for all, or sometimes even for each cheque at banks).
Hotels will sometimes charge a lower rate for changing money, so if you can, check with them before heading to the exchange.
Banks are closed Fridays and Saturdays; some exchange offices are open.
