From the back office database. Don't they already access that when checking
contactless these days? Recent Oyster & Contactless developments rely on a
degree of connectivity that was but a dream less than a decade ago.

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.
