Do I need to have cash or can I use a bank app to show proof of funds when entering Thailand?

The discussion centers around the necessity of having a specific amount of cash (20,000 baht) upon arrival in Thailand for those seeking visa-exempt entry. Responses indicate that while regulations technically require cash, many travelers report not being asked about their cash availability. Some argue cash is necessary due to potential emergencies, while others share experiences of entering the country without the required amount but having alternative financial means.
