MONEY

US dollars are the most readily acceptable currency
for buying baht, and travelers checks get a better rate than cash.
British pounds are the next best option.
Banks or legal money changers offer the best rates.

Credit cards are becoming increasingly accepted in quality shops, hotels and restaurants.
Visa/PLUS is the most useful, followed by MasterCard/Cirrus;
American Express cards are not as widely accepted.
ATMs that accept Visa, MasterCard and other credit cards are easily found in the larger cities.
Also, many exchange booths will give you a cash advance on your credit card.
The baht comes in denominations of  20 (green), 50 (blue), 100 (red), 500 (purple) and 1000 (beige) notes.
There  are 100 sàtàang in one baht; coins include 25-sàtàang and 50-sàtàang pieces, and  one, five and 10 baht.
