While I haven't expended a lot of brain power on the issue I can't see
how contactless bank cards can be checked by any railway inspector. On
a bus the inspector obtains a print out from the driver's machine and
checks card numbers presented by passengers against the list. Given
you just tap your bank card on a reader on the rail network and there
is no "write" record on the bank card (AFAIK) then what is there to
check? The transaction data all goes to a "black box" for calculation
of fares and caps.

It's possible I have a knowledge gap about the card technology and
cards can be checked in some way that I'm unaware of.

Perhaps you can't tell by interrogating the card but you could log all
contactless cards that passengers claim to be using and then as part of
the overnight processing bill any cards that were checked by an inspector
but hadn't started a journey with a penalty fare.

Although that would leave the system open to abuse by people with pre-paid
cards, assuming they can be used at all and they aren't registered to
an individual.

TfL takes money out of your account later on when it thinks its owed it? I can
see that going down like a bucket of cold sick.

I've just logged onto the Contactless website and there is now a 'Today's
Travel' section that appears new. Could the gates/validators now be
close enough to online and real-time that an inspector could have an
online reader that checks with a central database, provided you aren't
currently in a tunnel?

I don't think the cards can be checked, but in theory an online gripper
could ask the back-office if they've seen any flying pigs delivering
that card number and an associated touch-in recently.

And the reverse, which is accidentally giving the gripper the "wrong"
card and hence creating an unresolved journey when in fact you had
touched in with another of your cards.
