Not in real time as far as I can tell, no. Contactless ticket checks
show on the journey history but take some hours to appear, it seems to
be updated after the event. Gate entry/exits take a few seconds to appear.

I wonder what if anything stops people using duff contactless cards, eg
ones for a closed account or one that was thought lost , cancelled , then
foundi
again? Presumably the only check the gate can do is whether the card is from a
valid bank and account type.

The first time it's used, probably nothing to stop it. Once the charge
"bounces", overnight, it'll probably be added to a local-to-TfL
block-list.

I suppose for TfL the most they can lose is the daily capped fare, but if
contactless starts to be accepted on national rail for longer journeys someone
could in theory fleece a TOC of a few hundred quid.

I wonder if there isn't a list, updated at least daily, of all withdrawn
credit card numbers (that were still in their period of validity)? That
would be small enough to be downloaded to portable devices for offline use.

Isnt't the max for contactless £40, hence that has to be the limit of
liability.

The trader can voluntarily, at their risk, accept them for a greater
sum.

Not very likely though in a National Rail context.

And that's before we've looked at the complexity of national roll-out of
the equivalent of pink route validators, and checking if the traveller
sat in First or Standard,

It seems to go up all the time.

I'm not aware it's increased above £30, a limit set in Sept 2015.

Which is why every informed commentary on the likelihood of a National
Rail contactless post-pay scheme says it's a pipe dream.
