I recently made transfers from my Bangkok Bank account to purchase a car. It appears that with new third-party transfers, there is a qualifying period. My transfers were capped at 500k per day, requiring me to contact the bank daily for each transaction. I completed one transfer one day and another on the day I picked up the car, using my laptop for enhanced security. It's advisable to inquire with your bank before attempting such a transfer. In my experience, the bank only answered specific questions when contacted and did not volunteer information for subsequent steps in the process, which I found quite frustrating and time-consuming, as it seems to operate on a 'need-to-know' basis.
