Thai banks are required by regulation to have facial recognition when transferring over 50k THB in one transaction or cumulative in a day. I believe most banks have shutdown their internet banking as it's not worth it for the low number of users to implement web-based secure facial recognition that don't allow you to feed spoofed video input. One of the bank that I use will send a push notification to their mobile app for you to confirm the transaction.

I believe that previously internet banking, even before mobile banking, will limit the number of transfer recipients you can add per day/month. With the rise of QR payment I could see this limit being regularly hit if you scrape the web-based banking.

Since the Bank of Thailand claims that they technically don't block many things (mobile banking technical requirements seems to also require blocking root, but they never banned internet banking), I wish there's a new bank that try to disrupt the existing players. But the latest "branchless" banking license were only acquired by existing banking groups, so API-first personal banking remain impossible.
