What are the financial requirements for entering Thailand as a tourist?

When entering Thailand, tourists may be asked to show proof of funds. While the official rule states that entry via visa exemption requires 10,000 baht, many travelers have reported being asked to show 20,000 baht at the airports like Don Mueang and Suvarnabhumi. Cash is generally required, and while travelers often discuss the acceptance of credit cards or travel money cards, immigration officers typically only accept cash. As a precaution, it's advisable for travelers to carry the required amount in cash to avoid potential denial of entry.
