I went to SCB after receiving said message and was told they are still trying to figure out how to handle the facial recognition issue with foreigners. And I was told same as others have mentioned that I can make multiple transactions of 49,XXX per day or call to clear a large transaction. A shame as I preferred to use SCB for my swift transfers and large payments due to the better exchange rates they offered.
On a similar note, I needed to visit the Kashikorn local branch on Friday (was inquiring about a debit card issue I had) and was asked for my bank book, passport and Debit card, the agent processed an update to my account adding facial ID (photo taken with her tablet), gave me an updated bank book and told me from now on I will need to use facial ID as a second security measure when making large transfers. So K bank figured out how to do it, also it seems BBL has as well, I will visit them on Monday to sort this out with BBL.
SCB is behind on this issue, I'm sure they will figure it out soon.
