If HEX had wanted smartcards it would have introduced them by now as
it's a simple self contained operation. I expect it is far keener to
get TfL's contactless card system installed off the back of Oyster
acceptance. Being able to use bank cards will likely appeal to a
large proportion of their regular users.

I wonder how many foreign-issued bank cards will work with the
contactless system?

If anything the UK is backward compared to the rest of the world on
contactless acceptance,

I was more concerned about contactless issuing, and the risks of
accepting foreign cards whose creditworthiness status can't be
determined in real time.

No ticket purchase and no queues will appeal to business travellers.

As a much travelled businessman (in general terms) I can assure you
that the lack of a paper receipt/ticket to attach to my expenses claim
is a huge disadvantage.

Other systems solve this problem easily, as you've been told before. NS's
system for Chipkaart produces a very nice online expenses claim receipt
(which is specifically valid for Dutch tax purposes in the case of
nominal/registered cards,) which is far more convenient than toting around
bits of paper - the same can be done for contractless cards.

No doubt I'd have to set up accounts [remember to, and have time to] for
every balkanised transport operator I used on a trip.

I see no reason why a printout from the TfL website would be
unacceptable for exes purposes

That's one of the Balkanised systems one would need to register with.
