While the official currency of Dubai (and the UAE) is the Dirham (AED), US Dollars are widely accepted in tourist areas, hotels, and larger retail establishments. However, the exchange rate offered by merchants is typically unfavorable compared to the official peg rate of 3.6725. For the best value, it is recommended to exchange currency at a licensed exchange house or use a debit/credit card with low foreign transaction fees. ATMs across Dubai dispense AED and are widely available in malls, metro stations, and commercial areas.
