it only applies to mobile banking transfers. The daily transaction limit for visa/master card payments are not revised yet. I think you can make visa card payments up to 500K per day. The amount differs from bank to bank and types of card.
It is a new regulation. Krungthai is also the same. If you want to make a transaction more than 50K , you will need to visit their branch and transfer money with your passport at a teller. There have been stricter controls and changes in bank policies due to recent scams.
