The Thai unit of currency is the baht, where 1 baht is divided into 100 satang. Notes are in denominations of 1,000 (brown), 500 (purple), 100 (red), 50 (blue), 20 (green) and 10 (brown) baht. Coins consist of 25 satang, 50 satang, 1 baht, 5 baht and 10 baht.
Most major currencies can be changed easily at hotels, tourist shops, all provincial banks, shopping centers and money changers. Rates of exchange at banks or authorised money changers are better than those at hotels and department stores. Travelers leaving Thailand may take out no more than 50,000 baht per person in Thai currency. Most outlets take all major credit cards and ATM machines are readily available, where the exchange rate is automatic. Some carry a sizeable surcharge per withdrawal so check with your credit card company beforehand. Not all ATM machines take all kinds of cards; many will not take Visa or MasterCard, or will take one but not the other. Please ensure that you look for the credit card logos on the ATM signs.
