I went in to Bangkok Bank yesterday and and got the face “scan” done, as well as some more details on how it’s going to work.
Apparently starting soon, anyone using the mobile banking app to transfer more than 50,000฿ at a time will have to be verified through the phone’s front facing camera. Amounts less than this are unaffected, as are ATM transfers. People can opt out but they won’t be able to transfer amounts larger than 50,000฿ using the mobile app.
It was done quite quickly at a local branch (a different branch in a different province from where i opened the account), though I am skeptical that the low resolution webcam they used to “scan” my face will provide a clear enough image.
