Went along to buy a new m/c today (Click 160), needed to pay them 62,500.
BKB app said NO. Transferred 12,500 to my other bank TTB, went for 50k transfer, 'You have exceeded your daily limit of 50kbht'. (Promtpay NO, bank transfer NO, transfer to my other bank NO).
Next message, 'Please take your ID card/Passport, and bank book to a BKB branch'
Had to walk to an ATM and get the extra 12,500bht out in cash.
So there you go BKB have already restricted transfers to 50kbht.
