Currency exchange is available at the major airports, in hotels, and in area banks. However, few Americans bother to exchange money, since American dollars are widely accepted. Some ATMs in Jamaica don't accept American ATM cards, while others will accept American ATM cards and dispense U.S. dollars. Major credit cards are widely accepted throughout the island, although cash is required at gas stations, in markets, and in many small stores. Discover and Diners Club are accepted at many resorts. The official currency is the Jamaican dollar. At this writing the exchange rate is about J$88 to US$1.
