in the UK this is already relatively common for online banking. I asked my bank to raise my daily transfer limit the other day for a property purchase and part of the process was recording a video of myself in their app.
And, of course, as barriers are raised it makes it very difficult for some portion of the population (and less convenient for everyone else). I have to change addresses for an older person at a couple of banks and I'm sure it's going to be a nightmare.
That being said, if instead of "use our custom app you've never seen to record a video" it's "just talk to a person with some standard video chat" then maybe it makes things a whole lot easier? But I don't see that being how it's implemented these days...
Yeah. It's still going to be a barrier for some people but I'm guessing most could get comfortable with it if they were forced to. But getting my dad to do anything that isn't a voice call is pretty much pulling teeth. (Except for using Amazon. I think a lot of things are more don't want to than can't.))
