Might as well just give up then, shut down the transport system, forget
about this modern living lark and go back to hunting on the savannah.
Though I imagine there'd still be one or two persistent voices around
the camp fire complaining long into the night about how things don't
work...
It would be interesting to know what it is about the cards which stops
them working.

Lack of a chain of agreement between TfL, some intermediary, the card
issuer, and the user. It's not a hardware or protocol issue and I think
it unlikely to be a software bug.

That's the sort of agreement I'd expect TfL to have multilaterally with
(eg) Visa on behalf of all the banks that already have agreements with
Visa.

I'd don't know why, years from the start of the project, a patchwork
quilt of bilateral agreements hasn't yet been completed.
