I agree, this will become a "killer app" - particularly for
non-London bus companies who don't wish to spend a fortune on the
infrastructure to do a PAYG smartcard

Although some (not many) are using ITSO instead, which has the advantage
that it works when you aren't paying (twirly card) and also supports
season tickets.

when the banks can do it for them.

Who owns and runs the capping system? And that's not just a TfL sort of
capping but bus companies where you buy an "all day" ticket, and then
swipe in with it multiple times during the day.
