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. -- Spud |

Presumably the only check the gate can do is whether the card is from a valid bank and account type. Given the frequency that people get cards cancelled these days due to unauthorised payments etc I assume they must have a refuse list that gets regularly distributed and updated to the gates - if not it's a massive revenue hole. I can imagine though that each card would work once, but for e.g. tube journeys by the time you touch out again it may well have been flagged and fail. Given the price of memory these days, you could easily store a card for each person in the UK in 0.5GB and CPU processing etc is such that it could be rapidly searched if organised correctly. Ok - transmitting it entirely would be tiresome, but presumably you'd only distributed e.g. minutely updates each of which would only be a handful of cards. |

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. -- Spud |

I wonder if there isn't a list, updated at least daily, of all withdrawn credit card numbers (that were still in their period of validity)?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. |

2017, Someone Somewhere remarked: if contactless starts to be accepted on national rail for longer journeys someone could in theory fleece a TOC of a few hundred quid. 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, -- Roland Perry |
