The currency in the United Arab Emirates is called the Dirham and is either abbreviated as AED or DH.
Banknote denominations: 5 AED, 10 AED, 20 AED, 50 AED, 100 AED, 200 AED and 500 AED. There are also the coins 1 dirham, 50 files, 25 files, 10 files, 5 files, and 1 file. The 1, 5, and 10 files are bronze-colored and quite rare in everyday life. The 25 and 50 files and the 1 dirham are silver-colored and often found.
A rough rule of thumb for exchanges: 1 EURO is around 4 DIRHAM, 1 USD is a little less. If you’re traveling here and something costs 100 dirhams, that’s roughly the equivalent of around 25 euros. If you want to tip the taxi driver or the bellhop 5 dirhams, that’s about 1.25 euros.
You can pay with all types of credit or master cards in addition to “cash”. In the malls, in many hotel lobbies, and on the street near banks, there are so-called “ATMs” that are ATMs where you can withdraw cash.
Don’t forget that you often have to have your credit card approved for use abroad by your bank. Otherwise, you will be without a working credit card and have to communicate with your bank from here.
