Samui might be a tropical island, but there is no shortage of ATMs, exchange services and banks. All major credit cards are welcome.
The Thai monetary unit is the Baht. The Baht is broken down in to 100 satang.
Coins used: 1, 5, 10, 25 and 50 Sataang - 1, 2, 5 and 10 Baht.
Notes used: 20, 50, 100, 500 and 1000 Baht.
If you take foreign currency in or out of Thailand and the amount is equal to or greater than US $20,000 it must be declared at Thai Customs.
If taking Thai Baht out of Thailand to neighbouring countries the limit is 500,000 Baht. To other foreign countries the limit is 50,000 Baht.
Major foreign currencies can be exchanged at local banks and exchange counters in Samui. Lesser-known currencies may not be accepted. If you want to bring cash it would be better to bring US dollars. Traveller’s Cheques are a safer option and command a higher exchange rate than cash.
Most exchange counters are open from 7.00 am to 9.00 pm, 7 days a week including public holidays. Banking hours are 8.30 am to 4.00 pm, Monday to Friday, excluding public holidays.

All major credit cards are accepted in tourist areas of Koh Samui. Although we’d advise using cash for day to day living for your own convenience and card security.
