Thai Banks only have offices in Pattaya, but most of them have good international connections.
Banking Hours:
Monday-Friday 9:30 am-3:30 pm. Banks do not close for lunch.
All mayor currencies as well as Credit Cards are accepted, but you need to take your passport with you.
Almost all Thai Banks run Automated Teller Machines (ATMs). Usually the ATMs are accessible around the clock. Most ATMs accept such international connecting systems as Cirrus, Plus, NYCE, Visa and MasterCards.
