Can I use a foreign credit card in Thailand and what are the limits?

You can use foreign credit cards in Thailand, especially at larger vendors who accept them, but small vendors may not. Be aware of foreign transaction fees your card might charge. It's advisable to choose to pay in Thai Baht to avoid unfavorable exchange rates. Your credit limit usually remains the same as in your home country, but you should notify your card issuer of your travel to avoid declined transactions, especially for large purchases.
