I rather think TfL would garner more complaints than praise
if they paid staff/contractors to go and acquire contactless cards from
every single issuer of the same in every country which issues them or
paid holders of every such card to come to London to test their cards.

They should be able to get "test" cards from all the major issuers (who
are international organisations so a single point of contact for such an
exercise), who have a vested interest in as wide as possible acceptance.

And I doubt they'd get very far by asking for contactless cards, linked
to accounts with funds, to be sent to them for test transactions.

Quite the reverse, I expect the issuers will be testing things like this
too, and it's just part of their [considerable] costs for the
contactless rollout. And in any event the funds successfully taken from
the cards will go straight back to the issuers, as will the unsuccessful
cards.

So I am unclear what you expect or propose that TfL do to provide
better guidance.

Under their noses is a crowd-sourced database of cards-which-work. I
find it hard to believe they aren't using that.

So if they want to know if a particular type of card works, they just
trawl through the 60 million card usages they've had in the last six
months and see if that card is represented within.

In the meantime it seems to me TfL's guidance is the converse of the way
card issuers don't guarantee their contactless cards will be accepted by
every reader in every country.

TfL is hardly "any reader".
