You must have been living under a rock if you find that bizarre.
I had to attend two banks in person so that they could "scan my face", just because a few of their customers are too dumb to keep their accounts safe and secure.
My phone number has been the same since 15 years, has been registered with my banks since then amd has been registered in my name with my passport since that became a requirement in 2015. Still, ONE of my banks was too inept to match the information and demanded to see a written confirmation from AIS. The other banks didn't, and of course, the data does match.
That's more hassle judt within the last months than I had had in more than a decade before - back then, things JUST WORKED and kept working without intervention.
We're not even done yet, now Kasikorn Bank just managed to roll out the "face scan" for foreigners as well, so I'm looking forward to yet another bank visit which is a complete waste of my time.
