Automated Teller Machines (ATM) are plentiful throughout Thailand, and most accept cards of the major international networks (Plus, Cirrus, etc.)  Travelers Checks are generally accepted only at exchanges, and not elsewhere.  (leave them at home and travel with your ATM cards)

Major credit cards such as Visa, Mastercard, are accepted at most hotels, restaurants and major shops.  American Express is excepted in some larger or high end establishments.  Many businesses will charge you anywhere from 3% to 5% to put your purchases on a credit card.  However, larger hotels and shopping malls will honor the card at no extra charge. 

If you on an extended stay in Thailand, you might find it convenient to open a 'SAVINGS' bank account in one of the major Thai banks (Bangkok Bank, Kasikorn Bank, Siam Commercial Bank). You'll only need your passport and 200 baht to pay for the debit card that will be issued within minutes (you can also choose your pin code). You'll be able to take money at any ATM. There will be a small charge (20 baht) when you withdraw from other banks. In addition some cards allow you to pay directly in hotels, restaurants, shops.  You can request an "International debit card" which you will be able to use back home.  No reason to carry alot of money around, as there are ATM's on just about every street corner throughout Thailand.
