Do I need to show cash or a bank statement when entering Thailand on a visa-exempt status?

When entering Thailand on a visa-exempt basis, it is generally suggested to carry 20,000 THB in cash (or its equivalent), although many travelers report they are rarely asked to show this amount. Some sources recommend being prepared with the cash just in case, especially when crossing through land borders, while the Certificate of Entry program may have reduced the likelihood of being questioned at airports.
