In regards to the transaction limit on a KBank bank savings account. I've just spoken the KBank they confirm the single transaction limit is 50kthb with the total daily limit also 50kthb. He said there is a project at the bank to apply face recognition to the account at which time they will allow higher amounts.

Also if you have a debit card on your account you can make purchases up to 500kthb depending on your credit with the bank, so can make purchases at shops and the like. This seems high to me but I asked him twice. Cash from a ATM is 30kthb a limit of the cash machine. He also said you could make transfers on the card up to 1m. Really?

Not necessarily a visa question but I would imagine you need it, can you get a Thai credit card or are you better off with one from your home country - Australian
