I still don't understand how that tells it which of the two valid
cards to use.

If it got an answer from both (with a suitable separation), it could
decide to use the season ticket rather than the PAYG. Doesn't have to
take just the first one, especially just after it had detected a clash.

I suppose, but that still doesn't help in the many cases where there
is no clear reason to prefer one card over another.

If I have two+ contactless credit cards then I really don't care which
of them TfL use, as long as they only use ones I've signed up to my
"capped account" of course.

It seems a poor use of funds to redo the gates when it will only help
sometimes.

I think they've vastly underestimated the number of people with more
than one 'rfid' card. In the near future there are likely to be lots of
people with at least one ITSO card, as well as one Credit Card, even if
they have decided to give up on Oyster.

Like I said, people will get wallets that more or less solve the
problem.

I've already had to do that (perhaps six years ago). How many different
wallets do they want people to have?

And remember that one of the USPs of Oyster was *not* needing to take it
out of your wallet to use.
