The person you’re replying to said “hard to consider”, they didn’t say it was “impossible for”. There is an infinity of difference. Presumably banks and paymen

The person you’re replying to said “hard to consider”, they didn’t say it was “impossible for”. There is an infinity of difference. Presumably banks and payments systems aren’t using web technologies (one would hope) to do the actual payments and transfers. They use them as an interface to other systems in other languages. And most of them tend to push you hard to use their apps, bank websites are often subpar.
